Closed-Loop Stimulation in Left Bundle Branch Area Pacing

Resumen breve

This prospective, single-center, crossover study evaluated the effects of closed-loop stimulation (CLS) compared with conventional accelerometer-based rate-adaptive pacing (VVIR) in patients with permanent atrial fibrillation undergoing left bundle branch area pacing (LBBAP). Chronotropic responses were evaluated during standardized mental and physical stress testing. Heart rate distribution during daily activity, functional capacity, quality of life, and device-related parameters were also assessed.
