Objective：This study aims to investigate the successful rate of the left bundle branch area pacing（LBBP），the safety and effectiveness of the technology. Methods：Thirty-six patients were divided into LBBP group and RV pacing group according to the position of the RV lead. The baseline characteristics，successful rate，procedure time，paced QRS duration and pacing parameters were investigated. Results：In the presence of accumulated of the experience，the successful rate increased up to 88.9%. The thresholds of the LBBP group were lower than those of RVP group［（0.67 ± 0.14）V vs. （0.77 ± 0.23）V，P < 0.05］. The QRS duration of the LBBP group was narrower than that of RVP group［（112.50 ± 9.96）ms vs. （164.00 ± 19.32）ms，P < 0.05］. The pacing parameters during the follow up appeared to be stable with no complication occurred. Conclusion：LBBP was safe and effective.
