The clinical benefit of cardiac resynchronization therapy (CRT) in heart failure patients with left bundle branch block (LBBB) has been demonstrated. However, a nonresponse rate of CRT nearly 1/3. Recent studies have reported left bundle branch pacing (LBBP) has achieved remarkable effect in CRT. This study aim to explore the efficacy and safety of LBBP in heart failure patients with LBBB.
