1Two patients returned to LAFB and the other two returned and deteriorated into LAFB + RBBB. 220 patients with multiple types of arrhythmias were included. 3No new arrhythmia appeared in the early postoperative period. CAVB: complete atrioventricular block; AVB: atrioventricular block; BBB: bundle branch block; CLBBB: complete left bundle branch block; LAFB: left anterior fascicular block; RBBB: right bundle branch block; CRBBB: complete right bundle branch block; IRBBB: incomplete right bundle branch block; AJT: atrioventricular junctional tachycardia; PAC: premature atrial contraction; PVC: premature ventricular contraction; AT: atrial tachycardia; VT: ventricular tachycardia.
