Pacemaker-like syndrome complicating slow pathway ablation for AV nodal reentrant tachycardia.
This case report describes pacemaker-like syndrome after successful slow pathway ablation for atrioventricular (AV) nodal reentrant tachycardia due to recurrence of single AV nodal echo beats during sinus rhythm. The resultant AV dyssynchrony was responsible for the symptom complex. Following ablation of retrograde ventriculoatrial conduction, the AV nodal echo beats were eliminated and the pacemaker-like syndrome resolved.
