ClinConnect Summary

This clinical trial is looking at how a specific type of heart lead, called the Left Bundle Branch Pacing (LBBP) lead, records electrical signals in the heart during daily activities. The study focuses on patients who have received an implantable cardioverter-defibrillator (ICD) or a cardiac resynchronization therapy defibrillator (CRT-D) to prevent dangerous heart rhythms like ventricular tachycardia (VT) and ventricular fibrillation. The main question is whether the LBBP lead can accurately and consistently detect these heart events during different activities, such as resting and walking, over a period of six months.

To participate in this study, individuals should be 18 years or older and must have recently received an ICD or CRT-D with the LBBP lead. Participants will have their heart signals recorded using a small device that they can wear at home. The study is not yet recruiting, so there will be more information available soon for those interested in joining. It's important to know that patients who are pregnant or those who have recently had their heart device replaced or upgraded will not be eligible for this study. Your involvement could help improve heart monitoring for many patients in the future!
