The main question it aims to answer is:\n\n• Does the LBBP lead can provide accurate, stable, and valid EGM for ICD\u002FCRT-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.",[69,70],"Ventricular Tachycardia (VT)","Ventricular Fibrillation","2026-05-06",{"date":73,"type":74},"2026-05-08","ACTUAL",{"date":76,"type":74},"2025-02-26",{"date":78,"type":65},"2026-07-31",{"name":5,"class":6},2]
