AI Article Synopsis
- A rapid atrial pacing led to a wide-complex tachycardia, characterized by intermittent ventriculoatrial block and QRS alternans.
- The electrophysiological study showed a short/negative HV interval, and premature ventricular complexes caused the tachycardia to stop.
- The findings indicate the presence of antidromic re-entrant tachycardia, involving a connection between the nodo-fascicular and the ventricles.
Article Abstract
A wide-complex tachycardia was induced with rapid atrial pacing, with intermittent ventriculoatrial block and QRS alternans. A short/negative HV interval was observed, and premature ventricular complexes resulted in the termination of the tachycardia. The findings at electrophysiology study were consistent with an antidromic re-entrant tachycardia involving a nodo-fascicular/ventricular connection.
