title: Heart failure: a unique presentation of typical atrioventricular nodal reentrant tachycardia.
abstract: Cardiomyopathy due to various ventricular and supraventricular arrhythmias, including isolated cases of atypical atrioventricular nodal reentrant tachycardia, have been described. In this case report typical slowfast atrioventricular nodal reentrant tachycardia resulting in cardiomyopathy is being documented for the first time. In the setting of depressed left ventricular function, an episode of tachycardia pushed this patient into heart failure. Radiofrequency ablation of the slow pathway was successful in eliminating her tachycardia with the return of left ventricular function to normal. A follow-up of two years post-ablation revealed the patient to be symptom-free.
