Pacing and sensing optimization of permanent His-bundle pacing in cardiac resynchronization therapy/implantable cardioverter defibrillators patients: value of integrated bipolar configuration

摘要

Aims The clinical implementation of His-bundle pacing (HBP) has been limited by concern over higher capture thresholds (CTs) and lower R-wave amplitudes (RWAs), when compared with right ventricular (RV) pacing. The aim of this study was to assess the optimal pacing configuration for HBP lead when incorporated with cardiac resynchronization therapy/implantable cardioverter defibrillators (CRT-D/ICD) by testing of an integrated bipolar configuration.
