Cardioneuroablation in patients with vasovagal syncope: An updated systematic review and meta-analysis.

BACKGROUND: Cardioneuroablation (CNA) is a novel procedure that shows promising results in reducing syncope recurrence in patients with refractory vasovagal syncope (VVS). However, its effectiveness and safety remain controversial. OBJECTIVE: We performed an updated meta-analysis evaluating CNA efficacy and safety in patients with refractory VVS. METHODS: PubMed, Embase, and Cochrane databases were systematically searched for CNA studies in patients with refractory VVS. Our primary efficacy end point was syncope recurrence, and our safety end point was periprocedural complications. Prespecified subgroup analyses were performed for (1) the ganglionated plexus (GP) targeting method and (2) the GP location of ablation. RESULTS: We included 27 observational studies and 1 randomized controlled trial encompassing 1153 patients with refractory VVS who underwent CNA. The median age was 39.6 years, and follow-up was 21.4 months. The overall weighted rate of syncope recurrence after CNA was 5.94% (95% confidence interval [CI] 3.37%-9.01%; I2 = 64%), and the rate of periprocedural complications was 0.99% (95% CI 0.14%-2.33%; I2 = 0%). Our prespecified subgroup analysis using the GP targeting method and GP ablation location showed a higher prevalence of syncope recurrence in the electroanatomic mapping subgroup (6.21%; 95% CI 2.93%-10.28%; I2 = 0%) and in the right atrium approach (15.78%; 95% CI 3.61%-33.14%; I2 = 65.2%). CONCLUSION: This study supports the efficacy and safety of CNA in preventing syncope recurrence in patients with VVS. Furthermore, the electroanatomic mapping method of GP targeting and the right atrium approach were associated with a higher syncope recurrence rate than other methods.

Perfiles de Personalidad en adolescentes con Trastornos por Ansiedad en Población General y Clínica / Personality Profiles in Adolescents with Anxiety Disorders in General and Clinical population

La personalidad es el trasfondo que determina la forma de pensar, sentir y comportarse e influye en la psicopatología. En este contexto, resulta relevante el estudio de la relación entre personalidad y ansiedad en la adolescencia. El principal objetivo de nuestro estudio es analizar las diferencias entre casos con Trastornos por Ansiedad (TA) y una muestra de población general (PG) en los diferentes perfiles / prototipos de personalidad (PRP) derivados del el Inventario clínico para adolescentes de Millon (MACI). Un segundo objetivo fue estudiar el modelo más parsimonioso de PRP capaz de predecir TA. Para responder a estos objetivos se utilizó un diseño observacional analítico y se realizó un muestreo aleatorio de adolescentes en PG (n = 461) y consecutivo de pacientes con TA, valorados según criterios DSM-5 (n = 77). Los instrumentos de medida utilizados fueron el MACI y Adolescent Symptom Inventory. Los PRP Introvertidos, Inhibidos, Pesimistas, Sumisos, Oposicionistas, Autopunitivos y Límites presentan una media significativamente mayor en TA y los PRP Histriónico y Egocéntrico en PG. El modelo más parsimonioso de PRP que mejor predice TA está conformado por tener mayor edad y los PRP más límite y menos rebelde. El estudio ofrece una imagen novedosa de los PRP en casos de TA que invitan a su estudio clínico, favoreciendo nuevos caminos de investigación que incluyan la personalidad en la heterogeneidad del trastorno.

Personality is the background that determines the way we think, feel and behave and influences psychopathology. In this context, the study of the relationship between personality and anxiety in adolescence is important. The main objective of our study is to analyse the differences between cases with Anxiety Disorders (AD) and a sample of general population (GP) in the different personality profiles / prototypes (PRP) derived from the Millon Adolescent Clinical Inventory (MACI). Secondary objective: to study the most parsimonious predictive model of PRP to predict AD. To respond to these objectives, an observational analytical design was used and a random sampling of adolescents in GP (n = 461) and consecutive sampling of patients with AD, assessed according to DSM-5 criteria (n = 77) was performed. The measurement instruments used were the MACI and the Adolescent Symptom Inventory. Introverted, Inhibited, Doleful, Submissive, Oppositional, Self-demeaning and Borderline PRPs present a significantly higher mean in AD and the Dramatizing and Egotistic PRPs in GP. The most parsimonious PRP model that best predicts AD is shaped by having older age and the most Borderline and least Unruly PRPs. The study offers a novel picture of PRPs in AD cases that invite their clinical study, favoring new paths of research that include personality in the heterogeneity of the disorder. (AU)

A Six-Gene Prognostic and Predictive Radiotherapy-Based Signature for Early and Locally Advanced Stages in Non-Small-Cell Lung Cancer.

Non-small-cell lung cancer (NSCLC) is the leading cause of cancer death worldwide, generating an enormous economic and social impact that has not stopped growing in recent years. Cancer treatment for this neoplasm usually includes surgery, chemotherapy, molecular targeted treatments, and ionizing radiation. The prognosis in terms of overall survival (OS) and the disparate therapeutic responses among patients can be explained, to a great extent, by the existence of widely heterogeneous molecular profiles. The main objective of this study was to identify prognostic and predictive gene signatures of response to cancer treatment involving radiotherapy, which could help in making therapeutic decisions in patients with NSCLC. To achieve this, we took as a reference the differential gene expression pattern among commercial cell lines, differentiated by their response profile to ionizing radiation (radiosensitive versus radioresistant lines), and extrapolated these results to a cohort of 107 patients with NSCLC who had received radiotherapy (among other therapies). We obtained a six-gene signature (APOBEC3B, GOLM1, FAM117A, KCNQ1OT1, PCDHB2, and USP43) with the ability to predict overall survival and progression-free survival (PFS), which could translate into a prediction of the response to the cancer treatment received. Patients who had an unfavorable prognostic signature had a median OS of 24.13 months versus 71.47 months for those with a favorable signature, and the median PFS was 12.65 months versus 47.11 months, respectively. We also carried out a univariate analysis of multiple clinical and pathological variables and a bivariate analysis by Cox regression without any factors that substantially modified the HR value of the proposed gene signature.

Pilot Study on the Effects of the Teaching Interpersonal Skills Program for Teens Program (PEHIA).

BACKGROUND/OBJECTIVE: Social skills are essential in adolescence, both for their relational dimension and for their influence on other areas of adolescent life, so it is essential to include Social skills in the formal education of students. METHOD: This paper presents the results of an experimental mixed factorial design pilot study in which an Interpersonal Skills Training Program for Adolescents (PEHIA) was applied. The convenience sample consisted of 51 adolescents. An evaluation was carried out before and after the intervention, using the CEDIA (Adolescent Interpersonal Difficulties Assessment Questionnaire) and SAS-A (Social Anxiety Scale for Adolescents) questionnaires. RESULTS: The mixed factorial ANOVA show significant differences in the overall measures and in most of the subscales of both questionnaires, indicating that PEHIA is effectiveness, at least in the short term. CONCLUSIONS: The results obtained in assertiveness, interpersonal relationships and public speaking suggest that the program is feasible and shows promising results in reducing anxiety. However, a larger scale study should be conducted.

A three-dimensional printed customized bolus: adapting to the shape of the outer ear.

BACKGROUND: The skin-sparing effect of megavoltage-photon beams in radiotherapy (RT) reduces the target coverage of superficial tumours. Consequently, a bolus is widely used to enhance the target coverage for superficial targets. This study evaluates a three-dimensional (3D)-printed customized bolus for a very irregular surface, the outer ear. MATERIALS AND METHODS: We fabricated a bolus using a computed tomography (CT) scanner and evaluated its efficacy. The head of an Alderson Rando phantom was scanned with a CT scanner. Two 3D boluses of 5- and 10-mm thickness were designed to fit on the surface of the ear. They were printed by the Stratasys Objet260 Connex3 using the malleable "rubber-like" photopolymer Agilus. CT simulations of the Rando phantom with and without the 3D and commercial high density boluses were performed to evaluate the dosimetric properties of the 3D bolus. The prescription dose to the outer ear was 50 Gy at 2 Gy/fraction. RESULTS: We observed that the target coverage was slightly better with the 3D bolus of 10mm compared with the commercial one (D98% 98.2% vs. 97.6%).The maximum dose was reduced by 6.6% with the 3D bolus and the minimum dose increased by 5.2% when comparing with the commercial bolus. In addition, the homogeneity index was better for the 3D bolus (0.041 vs. 0.073). CONCLUSION: We successfully fabricated a customized 3D bolus for a very irregular surface. The target coverage and dosimetric parameters were at least comparable with a commercial bolus. Thus, the use of malleable materials can be considered for the fabrication of customized boluses in cases with complex anatomy.

Multiple myeloma and SARS-CoV-2 infection: clinical characteristics and prognostic factors of inpatient mortality.

There is limited information on the characteristics, prognostic factors, and outcomes of patients with multiple myeloma (MM) hospitalized with COVID-19. This retrospective case series investigated 167 patients reported from 73 hospitals within the Spanish Myeloma Collaborative Group network in March and April, 2020. Outcomes were compared with 167 randomly selected, contemporary, age-/sex-matched noncancer patients with COVID-19 admitted at six participating hospitals. Among MM and noncancer patients, median age was 71 years, and 57% of patients were male; 75 and 77% of patients, respectively, had at least one comorbidity. COVID-19 clinical severity was moderate-severe in 77 and 89% of patients and critical in 8 and 4%, respectively. Supplemental oxygen was required by 47 and 55% of MM and noncancer patients, respectively, and 21%/9% vs 8%/6% required noninvasive/invasive ventilation. Inpatient mortality was 34 and 23% in MM and noncancer patients, respectively. Among MM patients, inpatient mortality was 41% in males, 42% in patients aged >65 years, 49% in patients with active/progressive MM at hospitalization, and 59% in patients with comorbid renal disease at hospitalization, which were independent prognostic factors on adjusted multivariate analysis. This case series demonstrates the increased risk and identifies predictors of inpatient mortality among MM patients hospitalized with COVID-19.

A NKp80-Based Identification Strategy Reveals that CD56neg NK Cells Are Not Completely Dysfunctional in Health and Disease.

Natural killer (NK) cells are usually identified by the absence of other lineage markers, due to the lack of cell-surface-specific receptors. CD56neg NK cells, classically identified as CD56negCD16+, are very scarce in the peripheral blood of healthy people but they expand in some pathological conditions. However, studies on CD56neg NK cells had revealed different results regarding the phenotype and functionality. This could be due to, among others, the unstable expression of CD16, which hinders CD56neg NK cells' proper identification. Hence, we aim to determine an alternative surface marker to CD16 to better identify CD56neg NK cells. We have found that NKp80 is superior to CD16. Furthermore, we found differences between the functionality of CD56negNKp80+ and CD56negCD16+, suggesting that the effector functions of CD56neg NK cells are not as diminished as previously thought. We proposed NKp80 as a noteworthy marker to identify and accurately re-characterize human CD56neg NK cells.

Eficacia de dos tratamientos cognitivoconductuales en personas con fibromialgia y afectación emocional / Efficacy of two cognitive-behavioral treatments in people with fibromyalgia and emotional involvement

La fibromialgia afecta en gran medida a la calidad de vida de las personas que la sufren, así como a su funcionalidad, especialmente si la persona presenta síntomas comórbidos de ansiedad y/o depresión, lo que resalta la importancia del tratamiento psicológico. El objetivo del presente trabajo es comparar la eficacia de dos tratamientos cognitivo-conductuales breves en personas con diagnóstico de fibromialgia y con afectación emocional. Participaron un total de 44 personas (42 mujeres y 2 hombres) divididos en dos grupos de tratamiento: uno de ellos elaborado únicamente con componentes convencionales de la terapia cognitivo-conductual (grupo A) y el otro con los mismos componentes más un componente añadido de expresión emocional a través del dibujo (grupo B). Se encontraron puntuaciones significativamente mejores (p < 0,05) después de aplicar cualquiera de los dos tratamientos en las siguientes áreas: funcionalidad, percepción del dolor, ansiedad, depresión, catastrofismo, miedo al movimiento, estrategias de afrontamiento activo y percepción de autoeficacia. Se concluye que los resultados obtenidos apoyan la eficacia de ambos tratamientos cognitivo conductuales para personas con fibromialgia y afectación emocional

Fibromyalgia largely affects the life quality of people suffering from it, as well as its functionality, especially if the person has comorbid symptoms of anxiety and/or depression, which highlights the importance of psychological treatment. The objective of this study is to compare the efficacy of two brief cognitive-behavioral treatments in people with a fibromyalgia diagnosis and emotional involvement. A total of 44 people enrolled in the study (42 female, 2 male), divided within two treatment groups: one of them made only with conventional components of cognitive-behavioral therapy (group A) and the other with the same components plus an added component of emotional expression through drawing (group B). Significantly better scores were found (p < 0.05) after applying any of the two treatments in the following areas: functionality, pain perception, anxiety, depression, catastrophism, fear of movement, active coping strategies and self-efficacy perception. It is concluded that the results obtained support the efficacy of both cognitive-behavioral treatments for people with fibromyalgia and emotional involvement

Evaluation of super-responders to cardiac resynchronization therapy in the presence of left bundle branch block and absence of scar in the posterolateral wall of the left ventricle.

Patients with heart failure (HF) undergoing cardiac resynchronization therapy (CRT) who exhibit above-expected improvement are known as super-responders. We assessed the rate of super-responders in a population with left bundle branch block (LBBB) > 150 ms in the absence of scar tissue in the left ventricular posterolateral wall as well as prognostic variables. In this prospective observational cohort study (n=20) an electrocardiogram (ECG) was performed pre- and post-CRT. The classic and Strauss LBBB criteria were adopted (> 150 ms). The percent (%) reduction of the QRS was calculated after implantation. All patients responded to the Minnesota Living with Heart Failure questionnaire and underwent an echocardiogram to measure left ventricular ejection function (LVEF), left atrium (LA) diameter, left ventricular end-systolic volume (LVEDV), left ventricular end-diastolic volume (LVESV), and left ventricular end-diastolic diameter (LVEDD) pre- and 6 months post-CRT. Cardiac magnetic resonance imaging (MRI) measured the presence of scar tissue in the posterolateral LV wall and the total scar burden (% LV mass). Fisher's exact test and the Mann-Whitney test were performed to evaluate possible prognostic variables. The mean age was 58.20±8.79 years old, 60% female, with a mean LVEF of 28.15±5.10%, ECG with LBBB mean QRS of 162.15±7.86 ms, LBBB > 150 ms with Strauss standard in 90% of cases, and 90% with non-ischemic cardiomyopathy. Twelve cases (60%) of super-responders (reduction > 30% LVESV after 6 months) were observed. Super-responders did not present a difference in response in sex (12 vs 8 P=0.67), age (58.67 vs 57.7 P=087), Minnesota quality of life (55.50 vs 67.70 P=0.2), % initial QRS reduction (21.16 vs 18.69 P=0.21), LVEF (29.25 vs 26.5 P=0.38), LVEDD (66.33 vs 67.67 P=0.83), LVEDV (211.16 vs 228.53 P=0.75), LVESV (145.83 vs 167.00 P=0.75), or LA diameter (41.58 vs 43.63 P=0.45). The presence of LBBB > 150 ms, using the Strauss standard (90%) and the absence of scar in the posterolateral wall may account for these positive results. Super-responders benefit the most from CRT, and the results of this study can contribute to a better selection of CRT candidates.

Relation of fractionated atrial potentials with the vagal innervation evaluated by extracardiac vagal stimulation during cardioneuroablation

BACKGROUND: Vagal hyperactivity is directly related to several clinical conditions as reflex/functional bradyarrhythmias and vagal atrial fibrillation (AF). Cardioneuroablation provides therapeutic vagal denervation through endocardial radiofrequency ablation for these cases. The main challenges are neuromyocardium interface identification and the denervation control and validation. The finding that the AF-Nest (AFN) ablation eliminates the atropine response and decreases RR variability suggests that they are related to the vagal innervation. METHOD: Prospective, controlled, longitudinal, nonrandomized study enrolling 62 patients in 2 groups: AFN group (AFN group 32 patients) with functional or reflex bradyarrhythmias or vagal AF treated with AFN ablation and a control group (30 patients) with anomalous bundles, ventricular premature beats, atrial flutter, atrioventricular nodal reentry, and atrial tachycardia, treated with conventional ablation (non-AFN ablation). In AFN group, ablation delivered at AFN detected by fragmentation/fractionation of the endocardial electrograms and by 3-dimensional anatomic location of the ganglionated plexus. Vagal response was evaluated before, during, and postablation by 5 s noncontact vagal stimulation at the jugular foramen, through the internal jugular veins (extracardiac vagal stimulation [ECVS]), analyzing 15 s mean heart rate, longest RR, pauses, and atrioventricular block. All patients had current guidelines arrhythmia ablation indication. RESULTS: Preablation ECVS induced sinus pauses, asystole, and transient atrioventricular block in both groups showing a strong vagal response (P=0.96). Postablation ECVS in the AFN group showed complete abolishment of the cardiac vagal response in all cases (pre/postablation ECVS=P<0.0001), demonstrating robust vagal denervation. However, in the control group, vagal response remained practically unchanged postablation (P=0.35), showing that non-AFN ablation promotes no significant denervation. CONCLUSIONS: AFN ablation causes significant vagal denervation. Non-AFN ablation causes no significant vagal denervation. These results suggest that AFNs are intrinsically related to vagal innervation. ECVS was fundamental to stepwise vagal denervation validation during cardioneuroablation.

Utilidade da estimulação vagal extracardíaca na elucidação de feixes anômalos ocultos durante ablação e estudo eletrofisiológico / Usefulness of extracardiac vagal stimulation in elucidating occult anomalous bundles during ablation and electrophysiological study

Confirmar se a condução ventrículoatrial [CVA] ocorre por via normal ou anômala [VA] é fundamental no diagnóstico e ablação [ABL] de taquicardias supraventriculares [TSV]. Neste estudo propomos uma alternativa de confirmar a presença de VAs ocultas, através da estimulação vagal extracardíaca [EVEC] considerando que esta bloqueia a condução pelo nó AV. MÉTODOS: 26 pcts, 27,9±15anos, 15(57,7%) sexo feminino, portadores de TSV: reentrada nodal [RN] 5(19%) e reentrada AV [RAV] 21(81%) com ou sem pré-excitação, submetidos à ABL por RF. A partir da punção femoral e veias jugulares internas D ou E, um cateter foi avançado até o nível do maxilar superior para EVEC(30Hz/50µs/0,5 a 1V/kg até 70V) sem contato com o vago. A CVA foi testada com e sem EVEC durante estimulação ventricular[EV], pré e pós-ABL. RESULTADOS: Em todos os casos, foi possível obter intensa ação vagal com supressão reversível do nó sinusal e nó AV. Antes da ABL, a CVA estava presente em todos os casos e foi bloqueada pela EVEC apenas nos casos sem VAs. Após a ABL, a CVA foi completamente bloqueada pela EVEC em todos os casos, mas reapareceu em um pct de RN. Em todos pct de RAV, a CVA não foi bloqueada pela EVEC pré-ABL, mas desapareceu ou foi bloqueada pela EVEC pós-ABL (tabela). CONCLUSÃO: O bloqueio da CVA por EVEC sugere ausência ou eliminação com sucesso de vias anômalas. O ressurgimento da CVA resistente à EVEC pós-ABL em uma RN pode ser explicado pela denervação nodal AV pela ABL do 3º gânglio cardíaco durante ABL da via lenta. Estes dados sugerem que a EVEC pode ser muito útil para revelar VAs anômalas septais difíceis que se confundem com a CVA por vias normais. (AU)

Implante de ressincronizador com eletrodo de ventrículo esquerdo em veia cardíaca média do seio coronário e eletrodo do ventrículo direito em posição não habitual / Resynchronizer implantation with left ventricular lead in the middle coronary sinus cardiac vein and right ventricular lead in unusual position

INTRODUÇÃO: A terapia de ressincronização cardíaca através da estimulação biventricular é um tratamento coadjuvante à terapia medicamentosa otimizada, em pacientes com insuficiência cardíaca congestiva (ICC) refratária, causada por disfunção ventricular esquerda crônica e distúrbios de condução intraventricular, promovendo melhora da função cardíaca e da qualidade de vida. RELATO DE CASO: M.S.,49 anos, sexo masculino, com diagnóstico de Hipertensão Arterial Sistêmica e Miocardiopatia Dilatada (fração de ejeção do ventrículo esquerdo ­ FEVE -de 20%), apresentando dispnéia aos moderados esforços. Realizada cintilografia com estresse farmacológico demonstrando hipocaptação persistente moderada e discreta transitoriedade na parede anterosseptal do ventrículo esquerdo além de déficit acentuado da função ventricular e ventrículo esquerdo(VE) com volumes aumentados; eletrocardiograma (ECG)apresentando bloqueio de ramo esquerdo (BRE) com QRS 160ms.Realizado estudo eletrofisiológico com intervalos P-A 60 ms, A-H 105 ms, potencial H 15ms, H-V 55ms, ponto de Wenckebach anterógrado 380 ms, duração do complexo QRS 200 ms - estimulação ventricular programada com três extra-estímulos decrescentes no ápice e na via de saída do VD não provocou arritmias ventriculares sustentadas. Em 22/01/2018 foi optado por implante de ressincronizador cardíaco, sendo colocado o eletrodo do VE através do seio coronário em veia cardíaca média e o eletrodo do ventrículo direito (VD), na via de saída do VD. Logo após foi realizado ECG cujo QRS reduziu em aproximadamente 100 ms. Após 4 meses foi realizado novo ecocardiograma transtorácico que evidenciou FEVE de 28% e presença de dissincronia mais acentuada em septo, parede lateral e médio-basal da parede inferior. Novo ECG apresentando ritmo de marca-passo com QRS de aproximadamente 100 ms e eixo desviado para direita +120 graus. O paciente evolui com melhora dos sintomas (NYHA I).Após um ano de seguimento, paciente assintomático, sendo realizado novo ECG com ritmo de marca-passo e morfologia de BRE, com QRS de 80 ms e eixo -45 graus. O paciente portador de marca-passo ressincronizador em topografia diferente do habitual apresentando excelente resposta clínica e eletrocardiográfica. DISCUSSÃO E CONCLUSÃO: A terapia de ressincronização cardíaca vem se tornando um tratamento de rotina em pacientes previamente selecionados, no caso apresentado o paciente portador de ressincronizador em topografia diferente do habitual apresentou uma boa resposta á terapêutica.

Estimulação cardíaca artificial septal, apical e bifocal: estudo comparativo por meio da ecocardiografia transesofágica intraoperatória / Septal, apical and bifocal artificial cardiac pacing: a comparative study using intraoperative transesophageal echocardiography

INTRODUÇÃO: A estimulação cardíaca convencional, apical de VD, produz um QRS largo com morfologia de BRE, o qual ocasiona dissincronismo mecânico ventricular. Este dissincronismo pode agravar ou provocar um quadro de IC. Dentro deste contexto, temos procurado novos sítios e novas formas de estimulação, em busca de um QRS mais estreito e uma contração ventricular menos dissincrônica. O posicionamento de 1 eletrodo septal ou de 2 eletrodos dando origem à estimulação Bifocal do VD tem se mostrando mais benéfico quando comparado à estimulação convencional apical do VD, em evolução a médio e longo prazo. Contudo, essas 3 formas de estimulação: septal, apical e bifocal de VD ainda não haviam sido comparadas através da ecocardiografia moderna para avaliação do dissincronismo e os efeitos imediatos dessas estimulações durante o implante. MÉTODOS: Pacientes em FA permanente, com FE entre 35% e 55% e bradicardia com necessidade de estimulação cardíaca, foram submetidos a implante de MP bifocal do VD (septal alta e apical). Durante o intraoperatório, após cada modo de estimulação, foram realizadas medidas eletrocardiográficas e avaliação do dissincronismo pelo Eco Transesofágico...(AU)

Distúrbios de condução e arritmias na sarcoidose cardíaca - relato de caso / Conduction disturbances and arrhythmias in cardiac sarcoidosis - case report

A forma cardíaca isolada da Sarcoidose é pouco frequente. no entanto, o envolvimento cardíaco na sarcoidose é mais prevalente e ocorre em 5 % desses pacientes. O diagnóstico de sarcoidose cardíaca é um desafio por causa das manifestações inespecíficas, sendo a sensibilidade e especificidade das modalidades diagnósticas limitadas. Este relato de caso teve por objetivo descrever o caso de um paciente sem diagnóstico prévio de sarcoidose com arritmias e distúrbio de condução ventricular compatíveis com acometimento cardíaco da doença. Optou-se para o tratamento um implante de marcapasso definitivo e terapia com corticosteroides

The isolated cardiac form of sarcoidosis is infrequent. However, cardiac involvement in sarcoidosis is more prevalent and occurs in 5% of these patients. The diagnosis of cardiac sarcoidosis is a challenge because of non-specific manifestations, and the sensitivity and specificity of the diagnostic modalities are limited. This case report aimed to describe the case of a patient without previous diagnosis of sarcoidosis with arrhythmias and ventricular conduction disturbance compatible with cardiac involvement of the disease. A definitive pacemaker implant and corticosteroid therapy were chosen for the treatment
