Comparison of arrhythmia prevalence for group II in respect to group I in the postoperative period
AVB = second degree atrioventricular (AV) block; aAVB = advanced AVB; SP = sinus pause; VPC = ventricular premature complex; VPC 2/3 = 2 or 3 consecutive VPCs; VEsC = ventricular escape complex; VT = ventricular tachycardia; RT = R-on-T phenomenon; APC = atrial premature complex; APC 2/3 = 2 or 3 consecutive APCs; AT = atrial tachycardia
