Abstract：Objective To investigate the effect of left bundle branch area pacing(LBBaP)on new-onset atrial fibrillation(NOAF)and atrial high rate episodes(AHREs)in patients with atrioventricular block(AVB).Methods Eighty-four patients with Ⅲ°AVB for pacemaker implantaion were divided into the LBBaP group(n=42)and the RVSP group(n=42)based on the site of the ventricular leads.The two groupswere compared in terms of the pre-and post-operative QRSd,ventricular pacing parameters,complications,incidence of stroke,NOAF and AHREs.Results(1)The incidence of postoperative NOAF and AHREs in the LBBaP group was significantly lower compared with RVSP group(P<0.05).(2)The p-QRSd in the LBBaP group was significantly shorter compared with RVSP group(P<0.05).(3)The two groups showed no significant differences in ventricular pacing parameters,incidence of complications and stroke events(P>0.05).Conclusion LBBaP is superior to right ventricular pacing in reducing the incidence of postoperative AHREs and NOAF in patients after implantation and improving the prognosis of patients.
