Background: The goal was to use surface electrocardiographic (ECG) indicators detect COVID-19's malignant arrhythmic potential.
 Methodology: In 51 COVID-19 patients and 40 control subjects, the ECG parameters PR, QT, QTc, QTd, TPe, Tpe/QTc were assessed. had substantially higher mean QTc (410.8 24.3 msec vs. 394.6 20.3 msec, p.001), (0.19 0.02 0.18 0.04, p =.036), median QTd (47.52 46.5) ...
