The stunned atrial lead: Transient malfunction of a permanent atrial pacer lead following acute myocardial infarction

Proximal right coronary artery occlusion caused transient loss of sensing and capture of the atrial lead of a permanent dual-chamber pacemaker. Forty-five days after percutaneous revascularization, the atrial lead was discovered to be functioning normally. We hypothesize that ischemia of the right a...

description Proximal right coronary artery occlusion caused transient loss of sensing and capture of the atrial lead of a permanent dual-chamber pacemaker. Forty-five days after percutaneous revascularization, the atrial lead was discovered to be functioning normally. We hypothesize that ischemia of the right atrium caused stunning of the atrial myocardium at the pacer–lead interface, which gradually improved following percutaneous coronary intervention (PCI), leading to return of lead function over time. So far only one similar case has been described in the literature.
