Description
Alejandro López-Pena and his team report a grave heart rhythm with a trace that misleads. Their case report from twenty twenty-six concerns an old man with a pacemaker. Ventricular tachycardia as a rule widens the ECG trace. A narrow trace as a rule points away from that finding.
The man had lasting atrial fibrillation and a full heart block. Checks on the device showed that his heart fully relied on pacing. Mapping found scar tissue beside the signal bundle in the heart wall. That spot is why the trace stayed oddly narrow in shape. Ablation at the scar kept the rhythm from coming back. No more such events came during follow-up. A pacemaker can hide a ventricular rhythm behind a narrow trace.
