RESUMEN
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.

A young primiparous lady presented with drug-refractory atrial tachycardia which had led to cardiomyopathy. Three attempts with electrical cardioversion were also unsuccessful. She was rescued by radiofrequency ablation.

Complete heart block following intracardiac surgical repair for complex congenital heart disease is not uncommon. In the presence of ventricular dysfunction, ventricular pacing alone may not improve the cardiac output. We report the feasibility and efficacy of endoepicardial atrioventricular sequential pacing in a case of postoperative complete heart block.
