Data are expressed as mean (SD) or median (IQR) for continuous variables and number (%) for categorical variables. AF, atrial fibrillation; AVB, atrioventricular block; COVID-19, novel coronavirus disease 2019; PAC, premature atrial contracts; PSVT, paroxysmal supraventricular tachycardia; PVC, premature ventricular contracts; NSAT, nonsustained atrial tachycardia; NSVT, nonsustained ventricular tachycardia; SVT, sustained ventricular tachycardia. aStatistical differences between the COVID-19 patients (standardization) and COVID-19 patients (nonstandardization) groups.
