Prevalence of cardiac ARRHYTHMIAs in patients recovering from COVID-19

Abstract Background The family of seven known human coronaviruses are known for their impact on the respiratory tract, not the heart. However, the most recent coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has marked tropism for the heart and can lead to myocarditis (inflammation of the heart), necrosis of its cells, mimicking of a heart attack, arrhythmias, and heart failure. These complications, which at times are the only features of coronavirus disease 2019 (COVID-19) clinical presentation, have occurred even in cases with mild symptoms and in people who did not experience any symptoms. Recent findings of heart involvement in young athletes, including sudden death, have raised concerns about the current limits of our knowledge and potentially high risk and occult prevalence of COVID-19 heart manifestations. Aim of the Work was to detect the prevalence of cardiac arrhythmias in patients recovering from COVID-19 and to find out if it is related to COVID infection. Patients and Methods This cross sectional study was to detect the prevalence of cardiac arrhythmias in patients recovered from COVID-19 and to find out its relation to COVID infection. It was carried out on one hundred patients who had been diagnosed as COVID-19 and came after recovery from one to six months Post COVID at Ain Shams University Hospitals .This study was carried out during a period of six months between November 2021 and May 2022. Results that among these 100 patients recovering from COVID-19, 17 % of them developed cardiac arrhythmias as follow; 7 (7%) were diagnosed as Inappropriate Sinus Tachycardia, 3 (3%) had PVCs arising from RVOT, 3 (3%) were diagnosed as PACs, 2 (2%) were diagnosed as Paroxysmal AF, 1 (1%) was diagnosed as SVT (AVRT) and 1 (1%) was diagnosed as 1st degree heart block. Conclusion we found that Inappropriate sinus tachycardia was the most prevalent Cardiac Arrhythmia in these patients recovering from COVID-19 (7%) while other arrhythmias had lower prevalence with RVOT PVCS found in 3 % of the studied group, PACs in 3%, Paroxysmal AF in 2%, SVT (AVRT) in 1% and 1st degree heart block in 1% of this studied population. Absolute Lymphopenia during the course of COVID-19 illness had an effect on the prevalence of Cardiac Arrhythmias in patients recovering from COVID-19. Correlation among these arrhythmias and symptoms of these patients was called Post COVID syndrome.
