Abstract
Background: The goal was to use surface electrocardiographic (ECG) indicators to 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, and Tpe/QTc were assessed. COVID-19 patients had substantially higher mean QTc (410.8 24.3 msec vs. 394.6 20.3 msec, p.001), Tpe/QTc (0.19 0.02 vs. 0.18 0.04, p =.036), and median QTd (47.52 vs. 46.5) values than the control group. Troponin levels were linked with heart rate (r = 0.387, p =.006) but not with ECG parameters (r = 0.387, p =.006).
 Conclusion: In Covid19 patients, several ventricular arrhythmia surface ECG predictors, such as QTc, QTd, and Tpe/QTc, are elevated. Because drugs used in COVID-19 patients have the potential to impact these parameters.

Because drugs used in COVID-19 patients have the potential to impact these parameters
Several surface electrocardiographic (ECG) markers have been used to predict the risk of ventricular arrhythmias, including the QT interval and QT dispersion (QTd), T wave peak-to-end interval (Tp-e), and Tp-e/QTc ratio [7,8,9]
We discovered that possible ECG arrhythmia indicators QTc, QTd, and Tpe/QTc were significantly elevated in Covid19 patients in our investigation
Summary
Comparable viruses have arrhythmogenic potential, and the drugs used to treat COVID-19 have a higher risk of causing arrhythmia [6]. Several surface electrocardiographic (ECG) markers have been used to predict the risk of ventricular arrhythmias, including the QT interval and QT dispersion (QTd), T wave peak-to-end interval (Tp-e), and Tp-e/QTc ratio [7,8,9]. The goal of this cross-sectional study was to see how COVID-19 affected surface ECG arrhythmia parameters like the QT interval, QTd, Tp-e, and Tp-e/QTc ratio. The goal was to use surface electrocardiographic (ECG) indicators to detect COVID-19's malignant arrhythmic potential
