No results posted yet for this study

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.
