AI Article Synopsis
- An elderly man with a dual-chamber pacemaker experienced symptoms of slow heart rate and severe AV block, leading to medical attention.
- Device checks showed issues with the right ventricle lead, indicating possible lead fracture, while the atrial lead was functioning normally.
- Due to his age and health conditions, doctors chose to implant a Micra AV pacemaker and adjust the existing device to maintain proper heart rhythm and function.
Article Abstract
An elderly gentleman with a dual-chamber pacemaker presented to our institution with symptoms of symptomatic bradycardia and high-grade atrioventricular (AV) block. Device interrogation revealed failure to capture in the right ventricle (RV) lead with bipolar pacing, high RV pacing threshold with unipolar pacing, and high impedance suggesting lead fracture. The atrial lead function was normal. Given his advanced age, gait instability, and dementia, the decision was made to proceed with Micra AV pacemaker implantation, while programming his dual-chamber pacemaker to AAIR mode, thus maintaining AV synchrony by tracking paced atrial impulses and providing ventricular pacing.
