Abstract:
Objective To investigate the feasibility and methodology of active fixation lead on patients under right ventricular outflow tract septum(RVOTS) pacing.Methods Fifty DDD pacemaker patients were enrolled 31 male,23 female,50~86 years old,mean age 67.7?8.6.Ventricular active fixation lead was implanted in the right ventricular apex(RVA) and RVOTS successively and pacing parameter was tested.Results The success rate of RVOTS active fixation lead implantation was 98.15%.Mean lead threshold was 0.73?0.12 V.Pacing QRS duration show a significant difference between RVOTS pacing and RVA pacing,130.45?18.24 and 153.11?20.10,respectively(P
