Material and method:Of the ECG parameters PR, QT, QTc, QTd, TPe, and Tpe/QTc were measured in 51 COVID-19 patients and 40 in control subjects. Results: Compared to control group mean QTc (410.8 +/- 24.3 msec vs. 394.6 +/- 20.3 msec,p < .001) and Tpe/QTc (0.19 +/- 0.02 vs. 0.18 +/- 0.04,p= .036) and median QTd (47.52 vs. 46.5) values were significantly higher in COVID-19 patients. Troponin levels were significantly correlated with heart rate (r = 0.387,p = .006) but not with ECG parameters. Conclusion:Several ventricular arrhythmia surface ECG predictors including QTc, QTd, and Tpe/QTc are increased in COVID-19 patients. Since medications used in COVID-19 patients have the potential to affect these parameters, giving importance to these ECG markers may have a significant contribution in decreasing disease-related arrhythmias.eninfo:eu-repo/semantics/openAccessMalignant ArrhythmiaCOVID-19QT ProlongationECGArticle10.1080/13685538.2020.176905823513621365324494202-s2.0-85086031226Q2WOS:000540091500001Q1
