ABSTRACT
Background: Cardiac arrhythias had a significant association with the increased mortality rate in COVID-19 patients in hospitals. The present study aimed to evaluate the frequency of supraventricular arrhythmias in COVID-19 patients and to assess the echocardiographic parameters and inflammatory biomarkers in COVID-19 patients who developed supraventricular arrhythmias. Method(s): This cross-sectional study enrolled 196 patients, 33 of them developed supraventricular arrhythmias during hospitalization in Zagazig University isolation hospital. Result(s): There was a statistically significant association between the occurrence of atrial fibrillation (AF) and both oxygen saturation and lymphocyte percentage, which was significantly lower in those with AF. There was a statistically significant association between the occurrence of AF and CORADS, C-reactive protein (CRP), and interleukin-6, which were significantly higher in those with AF. Younger age and higher oxygen saturation decreased the risk of supraventricular tachycardia among the studied patients. Increasing oxygen saturation decreased the risk of AF among the studied patients, while higher CRP significantly increased risk by 1.045 folds. Conclusion(s): Atrial arrhythmias, especially with AF considered prevalent in cases with COVID-19. The atrial arrhythmias were correlated with higher cardiac injury and inflammatory markers and elevated severe COVID-19 clinical manifestations. Regarding mortality in-hospital, the association between COVID-19 and atrial arrhythmias was independent. 2023 Journal of Indian College of Cardiology.Copyright © 2023 Intervention, Journal of Mental Health and Psychosocial Support in Conflict Affected Areas.
ABSTRACT
Background: The World Health Organization has declared SARS-CoV-2 a public health emergency and pandemic because of its fast spread [COVID-19 (coronavirus disease 2019)]. Cardiogenic shock and arrhythmias such as acute coronary syndrome and myocarditis have been documented in the scientific literature. Heart arrhythmias in COVID-19-infected patients have been the subject of several recent articles in the scientific literature. It was also shown to be linked to an increased mortality risk. Atrial fibrillation, atrial flutter, ventricular tachycardia, and ventricular fibrillation have all been recorded in the literature so far. Unexpectedly, a study found that 7 % of patients who didn't require intensive care unit treatment experienced arrhythmias, but 44 % of patients who required to be hospitalized in ICU. Repletion of electrolytes, withdrawal of drugs that cause arrhythmia, volume status management, or suppression of catecholamine surges in COVID-19 are some of the treatment options for arrhythmias. Objective: This study aimed to evaluate the potential mechanisms of cardiac arrhythmias especially of supraventricular tachycardia in COVID-19. Methods: The databases were searched for articles published in English in 4 data bases. PubMed, Google scholar, science direct and Boolean operators (AND OR NOT) had been used such as cardiac arrhythmia mechanisms, Covid-19 OR SARS-CoV-2 and in peer-reviewed articles between March 2005 and October 2021. Conclusion: The pathophysiology of COVID-19 can be divided into a series of different ways. Metabolic imbalances, acidosis, and hypoxia are all possibilities as causes. Additional research suggests neurohormonal and catecholaminergic stress may have a significant influence. © 2022, Ain Shams University Faculty of Medicine. All rights reserved.
