Transient ST-segment Elevation During Atrial Fibrillation Ablation from Septal Stretch by a Multipolar Mapping Catheter.

Abstract

ST-segment elevation (STE) is a very rare complication observed during various cardiac ablation procedures. We report an interesting case of transient STE elevation by inter-atrial septal stretch during introduction of a multipolar mapping catheter during pulmonary vein isolation procedure. We also discuss various mechanisms for this observation.
