Why the study?
Does a leadless ventricular pacemaker with accelerometer-based mechanical atrial sensing improve quality of life in patients with AV block and normal sinus function?
Does a leadless ventricular pacemaker with accelerometer-based mechanical atrial sensing improve quality of life in patients with AV block and normal sinus function?
Leadless ventricular pacemakers with accelerometer-based mechanical atrial sensing provide stable AV synchrony and improve quality of life at 3 months in patients with AV block.
May improve QoL with stable AV synchrony in AV block; hypothesis-generating for leadless sensing, pending randomized confirmation.
Accelerometer-based mechanical atrial sensing provided by a leadless pacemaker implanted in the right ventricle significantly improves quality of life in a select cohort of patients with AV block and normal sinus function. AVS remained stable through 3 months, and there were no system upgrades to dual-chamber pacemakers.
