Abstract
AbstractIntroductionCoronavirus disease‐2019 (COVID‐19) has cardiac manifestations. Data about electrocardiogram (ECG) changes after COVID‐19 recovery is limited in hemodialysis patients. We aimed to investigate the changes in ventricular repolarization parameters after COVID‐19 recovery in hemodialysis patients.MethodsFifty‐five hemodialysis patients who recovered from COVID‐19 infection were included. QT interval, Tp‐e interval, corrected QT (QTc), QTc dispersion, and Tp‐e dispersion values were determined on the patients' ECGs, taken before COVID‐19 and at least 1 month after recovery. The patients' data before COVID‐19 infection and after recovery were compared.ResultsIt was found that longest QTc (QTcmax) and QTc dispersion values after recovery were prolonged compared with pre‐infection period (427 ± 28 ms vs. 455 ± 26 ms, p = 0.000 and 39 ± 16 ms vs. 65 ± 20 ms, p = 0.000).ConclusionIn our hemodialysis patients, ventricular repolarization parameters increased after COVİD‐19 recovery. In hemodialysis patients, already predisposed to arrhythmic deaths, arrhythmia risk after COVİD‐19 recovery may become more pronounced.
