ObjectiveThe characteristics of discrete intracardiac electrograms in selective left bundle branch (SLBB) pacing (SLBBP) have not been described in detail previously. This study aimed to examine the effect of different high-pass filter (HPF) settings on discrete ventricular components in an intracardiac electrogram (EGM) and to analyze its possible mechanisms. MethodsThis study included 95 patients with indications of permanent cardiac pacing. EGMs were collected at four different HPF settings ...
