Objective: We aimed to detect the malignant arrhythmic potential of COVID-19 with surface electrocardiographic (ECG) markers.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.

通过心电图解释 COVID-19 疾病的致心律失常效应。

目的：我们旨在通过表面心电图（ECG）标志物检测 COVID-19 的恶性心律失常潜能。材料和方法：在 51 例 COVID- 19 名患者和 40 名对照组。结果：与对照组相比，平均 QTc（410.8 ± 24.3 毫秒对 394.6 ± 20.3 毫秒，p < .001）和 Tpe/QTc（0.19 ± 0.02 对 0.18 ± 0.04，p = . 036）和中位 QTd（47.52 对 46.5）值在 COVID-19 患者中显着更高。肌钙蛋白水平与心率显着相关（r = 0.387，p = .006），但与心电图参数无关。结论：COVID-19 患者中包括 QTc、QTd 和 Tpe/QTc 在内的几种室性心律失常表面心电图预测因子升高。由于 COVID-19 患者使用的药物有可能影响这些参数，
