Abstract

This is a typical example of a tachycardia-induced cardiomyopathy due to incessant tachycardia with moderately increased ventricular rate. This was due to nonreentrant atrioventricular nodal tachycardia that gave rise to two ventricular complexes for every atrial complex. It describes a rare finding of the presence of retrograde concealed conduction in the fast pathway. Curative catheter ablation led to improvement of symptoms with reversal of tachycardia-induced cardiomyopathy.
