Description
A heart whose upper chambers have gone silent still needs pacing, but the usual lead spots may sit in dead scar. Sae Ujiro and co-authors report a case in a 2024 paper where mapping found the one living patch. The patient, a 72-year-old man, had earlier had maze surgery for fibrillation plus repair of two heart valves.
After surgery he felt faint, and tracings showed atrial standstill with a slow junctional rhythm. Electrical mapping showed both atria almost fully scarred, with stray fibrillation walled off in two spots. One area near the AV node still conducted, and a lead placed there produced a near-normal beat shape. Its voltage ran low, though, so a ventricular lead was added as insurance. The report argues mapping should guide lead placement when the atria are mostly scar.
