    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.

    P Wave Dispersion in COVID-19
    (2022) Tuncer, Mustafa; Öztürk, Fatih; Çoldur, Rabia; Karaduman, Medeni; Güneş, Yılmaz
    The effects of COVID-19 on the heart are still not fully known. In this study, we investigated how COVID-19 affects the P interval. Electrocardiographies (ECG) of 30 COVID-19 patients and the control group consisting of 23 healthy volunteers were examined and dispersion (Pd) of the P wave was calculated. Compared to control group mean Pd (40,1±6,6 vs. 49,6±11,5, p=0,006) values were significantly higher in Covid19 patients. Increased Pd was observed as an indication that COVID-19 affects the atriums.
