- OBJECTIVE: COVID-19 infection is known to injure myocardial tissue and in-crease arrhythmic events. However, data on the subject is limited in the literature. In our study, our aim was to investigate possible arrhythmic damages in COVID-19 survivors using the frontal plane QRS-T [f(QRS)-T] angle and a few other ECG parameters. PATIENTS AND METHODS: 269 patients who recovered from COVID-19 between April 2020 and January 2021 were included into the study. Pre-admission electrocardiograms and first -month outpatient clinic control ECGs of the patients were compared. RESULTS: After COVID-19, left bundle branch block (p < 0.001), right bundle branch block (p < 0.001), right bundle branch block (p < 0.001), and atrial fibrillation (p < 0.001) rates had in-creased. Prolongation was detected in QRS du-ration (p < 0.001), QT interval (p=0.014), adjusted QT interval (p=0.007) and Tpe interval (p=0.012). F(QRS)-T angle (p < 0.001) and fragmented QRS rate (p < 0.001) were increased. CONCLUSIONS: It was observed in our study that even if patients survived COVID-19, permanent deterioration in ECG parameters may oc-cur.
