OBSERVATIONAL
Conditions
Summary
The goal of this observational study is to investigate the changes of LBB EGM during daily activities and overdrive pacing at the time of peri-implantation and up to 6-month follow-ups of ICD/CRT-D patients. The main question it aims to answer is: • Does the LBBP lead can provide accurate, stable, and valid EGM for ICD/CRT-D sensing and detection of ventricular tachyarrhythmia events? In each patient intracardiac EGMs of LBBP lead will be collected by ambulatory Holter monitor at the time of peri-implantation and up to 6-month follow-up. EGM collection will be collected at resting and walking conditions and overdrive pacing.
