RESUMO
Syncope can have devastating consequences, resulting in injuries, accidents or even death. In our ageing society, the subsequent healthcare usage, such as emergency room presentations, surgeries and hospital admissions, forms a significant and growing socioeconomic burden. Causes of syncope in the older adult include orthostatic hypotension, carotid sinus syndrome, vasovagal syncope, structural cardiac abnormalities, cardiac arrhythmias and conduction abnormalities. As stated in the recently published World Falls Guidelines, syncope in older adults often presents as falls, which is either due to amnesia for loss of consciousness, or pre-syncope leading to a fall, especially in those prone to falls with several other risk-factors for falls present. This difference in presentation can hinder the recognition of syncope. In patients with unexplained falls, or in whom the history comprises red flags for potential syncope, special attention to (pre)syncope is therefore warranted. When syncope is mistaken for other causes of a transient loss of consciousness, such as epileptic seizures, or when syncope presents as falls, patients are often referred to multiple specialists, which may in turn lead to excessive and unnecessary diagnostic testing and costs. Specialist services that are able to provide a comprehensive assessment can improve diagnostic yield and minimise diagnostic testing, thus improving patient satisfaction. Comprehensive assessment also leads to reduced length of hospital stay. Increasingly, geriatricians are involved in the assessment of syncope in the older patient, especially given the overlap with falls. Therefore, awareness of causes of syncope, as well as state-of-the-art assessment and treatment, is of great importance.

PURPOSE: Duplication of chromosome 22q11.2 due to meiotic non-allelic homologous recombination results in a distinct syndrome, chromosome 22q11.2 duplication syndrome that has some overlapping phenotypic features with the corresponding 22q11.2 deletion syndrome. Literature on immunologic aspects of the duplication syndrome is limited. We conducted a retrospective study of 216 patients with this syndrome to better define the key features of the duplication syndrome. METHODS: Single-center retrospective record review was performed. Data regarding demographics, clinical details, and immunological tests were compiled, extracted into a predetermined data collection form, and analyzed. RESULTS: This cohort comprised 113 (52.3%) males and 103 (47.7%) females. The majority (54.6%) of mapped duplications were between low copy repeat regions A-D (LCR22A to -D). Though T cell subsets were relatively preserved, switched memory B cells, immunoglobulins, and specific antibodies were each found to be decreased in a subset of the cohort. One-fifth (17/79, 21.5%) of patients had at least 2 low immunoglobulin values, and panhypogammaglobulinemia was found in 11.7% (9/79) cases. Four children were on regular immunoglobulin replacement therapy. Asthma and eczema were the predominant atopic symptoms in our cohort. CONCLUSION: Significant immunodeficiencies were observed in our cohort, particularly in B cells and antibodies. Our study expands the current clinical understanding and emphasizes the need of immunological studies and multidisciplinary approaches for these patients.

BACKGROUND: Congenital scoliosis(CS) is associated with multiple organs defect, and cardiac abnormalities have been reported commonly associated with CS. Hemivertebra is caused by the failure of vertebral formation, which is a major constitute of CS. Till now, few studies focus on the incidence and interrelationship of hemivertebra and concomitant cardiac abnormalities in congenital scoliosis. We aimed to analyze the cardiac defect in CS patients with or without hemivertebra, and further explore the incidence of cardiac defect between different types of hemivertebra. METHODS: The ultrasonic cardiography (UCG) results of surgically treated congenital scoliosis (CS) patients between 2015 and 2018 were retrospectively analyzed. Patients were divided into hemivertebra group and non-hemivertebra group according to preoperative CT. Patients with hemivertebra was further divided into sub-group by single/multiple or fully/partially/mixed segmented hemivertebra. Demographic information, radiographic data and cardiac abnormalities were statistically compared between groups. RESULTS: A total of 329 patients were analyzed, including 216 patients with hemivertebra and 113 patients without hemivertebra. UCG results were abnormal in 89 cases (27.1%), including 41 males(12.5%) and 48 females(14.6%). Hemivertebra group had comparable incidence of cardiac abnormalities with non-hemivertebra group (p = 0.517). No significant difference in the incidence of UCG abnormalities between single and multiple hemivertebra group (P = 0.246). Binary logistic regression analysis showed that female sex with multiple hemivertebra was a risk factor for abnormal UCG (P = 0.009, OR = 3.449). Cardiac abnormalities was comparable among fully, partially and mixed segmented hemivertebra group(P = 0.264). In abnormal UCG, 33 patients with hemivertebra had non-valvular abnormalities, and 48.5% (16/33) were septal defects. 28 patients had valvular abnormalities, most of them were mitral valve abnormalities, especially mitral valve redundancy, prolapse and insufficiency(82.1%, 23/28). No significant difference between the incidence of non-valvular and valvular abnormalities in patients with hemivertebra (P = 0.581). CONCLUSIONS: The incidence of abnormal UCG results was approximately 28.2% in CS patients with hemivertebra. Female patients with multiple hemivertebra had a higher risk of UCG abnormalities. Mitral valve abnormalities were the most common abnormality of UCG found in CS patients with hemivertebra. TRIAL REGISTRATION: retrospectively registered.

BACKGROUND: In patients with primary mitochondrial disease (MD), screening with electrocardiogram (ECG) and transthoracic echocardiography (TTE) is warranted according to current guidelines as structural cardiac abnormalities are frequent. This study aims to evaluate the cardiac phenotype of a large Dutch cohort of patients with MD and investigates whether ECG alone is sufficient for predicting structural cardiac abnormalities on TTE. METHODS: In this retrospective cohort study, genetically confirmed MD patients >18 years old with an available ECG and TTE were included. Newcastle Mitochondrial Disease Scale for Adults (NMDAS) scores were assessed. ECG's were evaluated for rhythm and conduction disorders, voltage criteria for left ventricular hypertrophy (LVH) and repolarization disorders. Echocardiographic evaluation included left and right ventricular volumes and function, and presence of LVH or concentric remodeling. RESULTS: In total, 200 MD patients were included with a median age of 45 years (IQR; 37-57) of whom 36% were male. Of all MD patients, 35% had abnormalities on ECG and 61% on TTE. Most frequent structural cardiac abnormalities on TTE were: global longitudinal strain > - 18% (54%), concentric remodeling (27%) and left ventricular (LV) ejection fraction <52% (14%). Patients with maternally inherited diabetes and deafness (MIDD) and mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) had the highest prevalence of ECG abnormalities (50% and 47%). TTE abnormalities were most prevalent in patients with MIDD (75%), followed by mitochondrial myopathy (MM) (55%), MELAS (47%) and Mitochondrial Epilepsy and Ragged Red Fibers (MERRF) (47%). MD patients with a high disease severity (NMDAS ≥21) had a higher prevalence of ECG abnormalities (44%, p = 0.039) and structural cardiac abnormalities (72%, p = 0.004) compared to patients with a NMDAS score of 11-20 and ≤ 10 (ECG: 34% and 19%; TTE: 63% and 39%). ECG abnormalities had a positive predictive value of 74% and a negative predictive value of 53% for structural cardiac abnormalities on TTE. CONCLUSION: MD patients frequently have cardiac involvement especially patients with MIDD, MELAS or high NMDAS score. ECG as sole screening parameter is insufficient to detect structural cardiac abnormalities.

Several studies have demonstrated the usefulness of cardiac troponin I (cTn) levels in predicting adverse clinical outcomes of patients with anerusmal subarachnoid hemorrhage (aSAH). However, it remains unclear whether cTn levels can be a useful factor in predicting adverse neurologic and cardiovascular outcomes regarding follow-up duration. The study aimed to evaluate the clinical value of cTn elevation among patients with aSAH. A systematic literature search was performed in PubMed and Cochrane to collect original studies that compared the adverse outcomes in patients with aSAH who had elevated cTn levels and those who did not have elevated cTn levels. Data on patient demographics and outcome measurements (mortality, major disability, delayed cerebral ischemia, cardiac dysfunction, and pulmonary edema) were extracted. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were computed by fitting a random effects model. A total of 4,117 patients with aSAH were included in the meta-analysis. Elevated cTn levels was associated with a higher all-cause mortality (OR 3.64; 95% CI 2.68-4.94; I2 = 22.05%), poor major disability (OR 2.27; 95% CI 1.5-3.37; I2 = 52.07%), delayed cerebral ischemia (OR 2.10; 95% CI 1.46-3.03; I2 = 13.80%), cardiac dysfunction (OR 9.20; 95% CI 4.31-19.60; I2 = 39.89), and pulmonary edema (OR 10.32; 95% CI 5.64-18.90; I2 = 0.00%). Additionally, elevated cTn levels was associated with higher mortality in prospective studies (OR 3.66; 95% CI 2.61-5.14) as well as when compared with studies with short-term and long-term follow-up periods. Patients with aSAH who had elevated cTn levels also tended to experience poor short-term major disability (OR 2.36; 95% CI 1.48-3.76). Among patients with aSAH, elevated cTn levels was associated with higher mortality and adverse neurologic and cardiovascular outcomes. Given its clinical value, cardiac troponin levels may be included in the assessment of patients withs aSAH.

BACKGROUND: Anorexia nervosa affects most organ systems, with 80% suffering from cardiovascular complications. AIMS: To define echocardiographic abnormalities in anorexia nervosa through systematic review and meta-analysis. METHOD: Two reviewers independently assessed eligibility of publications from Medline, EMBASE and Cochrane Database of Systematic Reviews registries. Studies were included if anorexia nervosa was the primary eating disorder and the main clinical association in described cardiac abnormalities. Data was extracted in duplicate and quality-assessed with a modified Newcastle-Ottawa scale. For continuous outcomes we calculated mean and standardised mean difference (SMD), and corresponding 95% confidence interval. For dichotomous outcomes we calculated proportion and corresponding 95% confidence interval. For qualitative data we summarised the studies. RESULTS: We identified 23 eligible studies totalling 960 patients, with a mean age of 17 years and mean body mass index of 15.2 kg/m2. Fourteen studies (469 participants) reported data suitable for meta-analysis. Cardiac abnormalities seen in anorexia nervosa compared with healthy controls were reduced left ventricular mass (SMD 1.82, 95% CI 1.32-2.31, P < 0.001), reduced cardiac output (SMD 1.92, 95% CI 1.38-2.45, P < 0.001), increased E/A ratio (SMD -1.10, 95% CI -1.67 to -0.54, P < 0.001), and increased incidence of pericardial effusions (25% of patients, P < 0.01, 95% CI 17-34%, I2 = 80%). Trends toward improvement were seen with weight restoration. CONCLUSIONS: Patients with anorexia nervosa have structural and functional cardiac changes, identifiable with echocardiography. Further work should determine whether echocardiography can help stratify severity and guide safe patient location, management and effectiveness of nutritional rehabilitation.

BACKGROUND AND PURPOSE: Cardiac involvement is observed in about 80% of subjects with myotonic dystrophy type 1 (DM1) and is mainly characterized by cardiac conduction and/or rhythm abnormalities (CCRAs), possibly leading to sudden cardiac death (SCD). Our objective was to investigate whether the gender difference may influence the cardiac involvement and SCD in DM1. METHODS: We analyzed prevalence and incidence of cardiological abnormalities in males versus females in 151 consecutive DM1 patients over a 35-year follow-up period. RESULTS: Fifty-five patients, 35 males (62.5%) and 20 females (42.5%), developed some type of CCRA during the follow-up period (mean 7.82 ± 6.21 years). CCRA overall, and specifically cardiac conduction abnormalities (CCAs), were significantly more frequent in males than in females (p = 0.043 and p = 0.031, respectively). CCRAs progressed in 16 males (45.7%) and six females (30%). Twenty-four patients, 14 males (25.0%) and 10 females (21.3%), died during the follow-up. Nine of them, six males (10.7%) and three females (6.4%), had SCD. After correction for Muscular Impairment Rating Scale progression, cytosine thymine-guanine expansion, and follow-up duration, a higher prevalence of CCAs was independently associated with male gender (p = 0.039), but independent association with gender was not detected for CCRAs overall, cardiac rhythm abnormalities, and SCD prevalence, even if prevalence was higher in males than females. CONCLUSIONS: The overall risk of occurrence of CCAs in DM1 is significantly higher in males than females regardless of genetic background and disease severity and progression. Moreover, the data also suggest a similar impact for male gender for CCRAs overall, CCAs, and SCD even if not statistically significant.

Transposition of great arteries (TGA) in association with total anomalous Pulmonary venous connection (TAPVC) is a rare anomaly, that is seldom reported in adulthood. While both the conditions are life threatening on their own, in combination they compensate for each other and can often present after weeks or months after birth. Transthoracic Echocardiography (TTE) can reliably diagnose this anomaly. Cardiac MRI can also be used to confirm the diagnosis. We describe a rare combination of TGA and TAPVC in an 18-year-old patient.

BACKGROUND: Cardiovascular disease is the leading cause of morbidity and mortality in children with chronic kidney disease (CKD). We aim to estimate the prevalence of cardiac abnormalities in children up to age 16 years with CKD and their association with various risk factors. METHODS: This cross-sectional observational study was conducted on 107 CKD children. We assessed the systolic and diastolic function using 2D echocardiographic evaluation and M-mode measurements of the left ventricle (LV) indexed for BSA and z-scores were calculated. Results were compared with age, sex, stage of CKD, anaemia, estimated glomerular filtration rate (eGFR) and various laboratory parameters. RESULTS: LV diastolic dysfunction was seen in 88%, followed by increased LV dimensions in 33.6%, LV systolic dysfunction in 16%, right ventricle systolic dysfunction in 11.2% while increased pulmonary artery (PA) systolic pressure was seen in 9.3% of cases. LV dimensions correlated directly with parathormone levels and inversely with eGFR, serum calcium and haemoglobin levels. Left ventricular hypertrophy correlated directly with parathormone while inversely with eGFR, serum calcium and haemoglobin. Ejection fraction directly correlated to eGFR and serum calcium while inversely related to parathormone. Left PA pressure directly correlated with age and inversely with eGFR. Right ventricular systolic function assessed by tricuspid annular plane systolic excursion correlated inversely with haemoglobin. CONCLUSION: LV diastolic dysfunction and increased LV dimensions were the most common cardiac abnormality in children with CKD. LV dimensions correlated directly with parathormone levels and inversely with eGFR, serum calcium and haemoglobin. Diastolic dysfunction positively correlated with serum creatinine and parathormone levels.

Muscular disorders are mainly characterized by progressive skeletal muscle weakness. There are several aspects that can be monitored, which are used to differentiate between the types of muscular disorders, ranging from the targeted muscle up to the mutated gene. An aspect that holds critical importance when managing muscular dystrophies is that most of them exhibit cardiac abnormalities. Therefore, cardiac imaging is an essential part of muscular disorder monitoring and management. In the first section of the review, several cardiac abnormalities are introduced; afterward, different muscular dystrophies' pathogenesis is presented. Not all muscular dystrophies necessarily present cardiac involvement; however, the ones that do are linked with the cardiac abnormalities described in the first section. Moreover, studies from the last 3 years on muscular disorders are presented alongside imaging techniques used to determine cardiac abnormalities.

BACKGROUND: A high prevalence of cardiac abnormalities has been reported in children with human immunodeficiency virus (HIV) taking antiretroviral therapy (ART) in sub-Saharan Africa. We investigated the incidence and progression of cardiac abnormalities among children taking ART in Zimbabwe. METHODS: A prospective cohort study was conducted at a pediatric HIV clinic from 2014 to 2017. Children with HIV aged between 6 and 16 years and taking ART ≥6 months were enrolled. Transthoracic echocardiography was performed at baseline and after 18 months. RESULTS: Of 197 participants recruited at baseline, 175 (89%; 48% female; median age 12 years, interquartile range 10-14 years) were followed up. The incidences of left and right heart abnormalities were 3.52 and 5.64 per 100 person-years, respectively. Stunting was associated with the development of any cardiac abnormality (adjusted odds ratio 2.59, 95% confidence interval 1.03-6.49; P = .043). Right ventricular (RV) dilatation persisted at follow-up in 92% of participants and left ventricular (LV) diastolic dysfunction in 88%. Cardiac abnormalities present at baseline reverted to normal over the follow-up period in 11 (6%). There was an overall increase in mean z scores for LV, left atrium (LA), RV, interventricular septum, and LV posterior wall diameters at 18 months (P < .001). CONCLUSIONS: Despite ART, children with HIV have a high incidence of cardiac abnormalities, with only a minority being transient. Mean z scores for LV, LA, RV, interventricular septum, and LV posterior wall diameters increased over a relatively short follow-up period, suggesting the potential for progression of cardiac abnormalities. Longer follow-up is required to understand the clinical implications of these abnormalities.

Myocardial infarction type 2 (MI type 2) is an elevation of cardiac biomarkers in a physiologically stressful state leading to demand-supply mismatch of oxygen. This type of myocardial infarction is commonly seen in hospitalized patients. Since the introduction of clear definition, diagnostic criteria and International Classification of Disease (ICD) codes, the diagnosis has become increasingly common. There still remains plenty to learn about MI type 2 especially prevention and treatment strategies. Studies have shown that there is increased mortality and morbidity associated with MI type 2 when compared to MI type 1, and there may be benefit in having a multi-disciplinary approach including cardiology when treating such patients. Secondary prevention therapies may also play a role in decreasing adverse events from MI type 2. However, randomized control trials are insufficient, and results of studies are cautiously interpreted. In this article we have assessed the current evidence on MI type 2 and the gap in literature that will potentially be the focus of future analyses.

BACKGROUND: Cardiovascular anomalies are more common in monochorionic twins, especially with twin-twin transfusion, compared to other twin types and to singletons. Because previous studies are based on fetal and neonatal echocardiography, more information is needed to study prevalence of cardiac anomalies in twin miscarriages, stillbirths, and children after the immediate neonatal period. METHODS: With specific attention to cardiac anomalies, we reviewed the medical records of 335 selected liveborn twin pairs from the Marshfield Clinic Twin Cohort (enriched for twin-twin transfusion) and all twins (175 pairs) identified in the Wisconsin Stillbirth Service Program cohort of late miscarriages and stillbirths. RESULTS: Structural cardiac defects occurred in 12% of liveborn monochorionic twin infants and 7.5% of stillborn infants with twin-twin transfusion compared to only 2% of liveborn dizygotic twins and no stillborn dizygotic infants. The most common cardiac lesion in liveborn twins was ventricular septal defect, which was usually isolated and discordant, preferentially affecting the smaller twin in monochorionic pairs. Among stillborn and miscarried monochorionic twins, the most common cardiac lesion was acardia. CONCLUSIONS: Monochorionic twins, particularly those with TTT, are at increased risk for a spectrum of structural cardiac malformations which we suggest may be related to asymmetry of the inner cell mass resulting in a smaller poorly perfused twin. In severe cases, limited cardiac and circulatory development in the affected twin leads to acardia. In less severe cases, the smaller infant has deficient septal growth that sometimes results in ventricular septal defect.

Cardiac abnormalities (echocardiographic wall motion abnormality (WMA), biomarker elevation of cardiac troponin (cTn), B-type natriuretic peptide (BNP), or N-terminal prohormone of B-type natriuretic peptide (NT-proBNP)) frequently occur after subarachnoid hemorrhage (SAH). The clinical significance of cardiac abnormalities after SAH remains controversial. This meta-analysis was performed to assess the association between cardiac abnormalities and patient outcomes, including delayed cerebral ischemia (DCI), poor outcome, and death in SAH patients. PubMed and Embase were searched for observational studies reporting an association between cardiac abnormalities and outcome after SAH that were published before 31 December 2017. We extracted data regarding patient characteristics, cardiac abnormalities, and outcome measurements (DCI, poor outcome, or death). Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Twenty-six studies involving 3917 patients were included in our data analysis. WMA showed significant associations with higher rates of DCI (RR, 2.03; 95% CI, 0.99-4.15), poor outcome (RR, 1.45; 95% CI, 1.08-1.93), and death (RR, 2.54; 95% CI, 1.59-4.05). cTn elevation was associated with an increased risk of DCI (RR, 1.48; 95% CI, 1.23-1.79), poor outcome (RR, 1.85; 95% CI, 1.49-2.30), and death (RR, 2.68; 95% CI, 2.19-3.27). Elevation of BNP or NT-proBNT was significantly associated with higher rates of DCI (RR, 1.87; 95% CI, 1.16-3.02). WMA and elevation of cTn, BNP, and NT-proBNP in SAH patients are associated with an increased risk of DCI, poor outcome, and death after SAH.

PURPOSE: In vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI) is generally regarded as an indication for fetal echocardiography due to a reported increased risk of congenital abnormalities including cardiac anomalies. In this study we evaluated the utility of fetal echocardiography after anatomic survey in an experienced center. METHODS: This was a retrospective case review of in vitro fertilization with intracytoplasmic sperm injection pregnancies who had echocardiography in our institution from January 1996 to October 2010. RESULTS: Records from 85 mothers and 110 fetuses were identified. During anatomic survey, six cardiac anomalies were identified, including four ventricular septal defects, one pulmonary-aortic disproportion, and one post-valvular pulmonary artery dilatation. At fetal echocardiography, two of the four ventricular septal defects were confirmed and an additional three were identified. The most common cardiac anomaly seen in our population of IVF-ICSI pregnancies was ventricular septal defect, which was identified in 3.6% of all cases in the neonatal period. Of ventricular septal defects identified in the prenatal period, 71% resolved before birth. CONCLUSION: In experienced centers, a fetal echocardiography may not be necessary if the 3 vessels tracheal view of the heart is evaluated and the heart is evaluated carefully for a ventricular septal defect.

It is known that calcium-containing phosphate binders are more closely associated with the progression of vascular calcification than non-calcium-containing phosphate binders. In this study, we investigated the effect of the non-calcium-containing phosphate binder, lanthanum carbonate on the progression of coronary artery calcification and cardiovascular abnormalities compared to that of calcium-containing phosphate binder in chronic kidney disease patients during the early period after initiating hemodialysis. This was a randomized open-label study in which patients were divided into the calcium carbonate or lanthanum carbonate group. We evaluated blood samples, coronary artery calcification using high-resolution computed tomography, and cardiac abnormalities using echocardiography prior to and after initiating hemodialysis. Cardiac dimension and systolic function were significantly improved in the lanthanum carbonate group compared to those in the calcium carbonate group. Although statistically significant differences were not observed in all the patients, only among patients with moderate coronary artery calcification, the changes in coronary artery calcification score at 18 months were significantly smaller in the lanthanum carbonate group than those in the calcium carbonate group. The percent change in coronary artery calcification at 18 months was significantly correlated with the serum fibroblast growth factor 23 levels at 18 months (r = 0.245, P < 0.05). This significant correlation was particularly strong in patients with moderate coronary artery calcification (r = 0.593, P < 0.001). Our study suggests that lanthanum carbonate ameliorates cardiac abnormalities, and may slow coronary artery calcification development in patients with moderate coronary artery calcification, during the early period following hemodialysis initiation.

Fetuses of diabetic mothers may have structural or functional cardiac abnormalities which increase morbidity and mortality. Isolated functional abnormalities have been identified in the third trimester. The aim of the present study was to assess fetal cardiac function (systolic, diastolic, and global myocardial performance) in the second trimester in mothers with gestational diabetes, and also to relate cardiac function with glycemic control. Mothers with gestational diabetes mellitus referred for fetal cardiac evaluation in the second trimester (between 19 and 24 weeks) from March 2015 to February 2016 were enrolled as case subjects in this study. Non-diabetic mothers who had a fetal echocardiogram done between 19 and 24 weeks for other indications were enrolled as controls. Functional cardiac variables showed a statistically significant difference in isovolumetric relaxation and contraction times and the myocardial performance index and mitral E/A ratios in the gestational diabetic group (p = 0.003). Mitral annular plane systolic excursion was significantly less in the diabetic group (p = 0.01). The only functional cardiac variable found abnormal in mothers with poor glycemic control was the prolonged isovolumetric relaxation time. Functional cardiac abnormalities can be detected in the second trimester in fetuses of gestational diabetic mothers and timely intervention can improve postnatal outcomes.

The cardiac activities such as the depolarization and the relaxation of atria and ventricles are observed in electrocardiogram (ECG). The changes in the morphological features of ECG are the symptoms of particular heart pathology. It is a cumbersome task for medical experts to visually identify any subtle changes in the morphological features during 24 hours of ECG recording. Therefore, the automated analysis of ECG signal is a need for accurate detection of cardiac abnormalities. In this paper, a novel method for automated detection of cardiac abnormalities from multilead ECG is proposed. The method uses multiscale phase alternation (PA) features of multilead ECG and two classifiers, k-nearest neighbor (KNN) and fuzzy KNN for classification of bundle branch block (BBB), myocardial infarction (MI), heart muscle defect (HMD) and healthy control (HC). The dual tree complex wavelet transform (DTCWT) is used to decompose the ECG signal of each lead into complex wavelet coefficients at different scales. The phase of the complex wavelet coefficients is computed and the PA values at each wavelet scale are used as features for detection and classification of cardiac abnormalities. A publicly available multilead ECG database (PTB database) is used for testing of the proposed method. The experimental results show that, the proposed multiscale PA features and the fuzzy KNN classifier have better performance for detection of cardiac abnormalities with sensitivity values of 78.12 %, 80.90 % and 94.31 % for BBB, HMD and MI classes. The sensitivity value of proposed method for MI class is compared with the state-of-art techniques from multilead ECG.
