Data are expressed as mean (SD) or median (IQR) for continuous variables and number (%) for categorical variables. AF, atrial fibrillation; AVB, atrioventricular block; CKMB, creatine kinase isoenzyme; COVID-19, novel coronavirus disease 2019; hscTnI, high-sensitive cardiac troponin I; PAC, premature atrial contracts; PVC, premature ventricular contracts; NSAT, nonsustained atrial tachycardia; NSVT, nonsustained ventricular tachycardia.
