Summary

This observational study looks at how signals from a left bundle branch pacing lead change during daily activities and overdrive pacing in 50 people with an ICD or CRT-D. Researchers want to see if these leads can accurately detect ventricular tachycardia or fibrillation. Participants will have their heart signals recorded at rest and while walking, right after implantation and again at 6 months.
