Abstract:
Objective To assess the effect of QRS duration (QRSd) and cardiac function during right ventricular apex(RVA) pacing,right ventricular outflow tract (RVOT) pacing and right ventricular bifocal (RV-Bi) pacing. Methods Eight patients underwent RVA pacing,RVOT pacing and RV-Bi pacing during pacemaker implantation operation.The ejection fraction (EF),stroke index (SV),cardiac output(CO),QRS QRSd,QRS axis (QRSa) were measured after each pacing at the same pacing frequency. Results Compared with RVA pacing,the EF,SV and CO increased during RVOT pacing and RV-Bi pacing.The cardiac function of RV-Bi pacing was significantly increased (P
