Incessant Focal Atrial Tachycardia Leading to Tachycardiomyopathy

A 22-year-old man presented with severe left ventricular (LV) dysfunction and progressive heart failure. The 12-lead electrocardiogram showed short runs of supraventricular tachycardia suggestive of focal atrial tachycardia. The patient underwent successful radiofrequency ablation. There was a complete recovery of symptoms and LV function at six months of follow-up. We discuss the importance of identifying tachycardiomyopathy as a reversible cause of heart failure.

Automated summary

This case highlights the successful treatment of left ventricular dysfunction caused by atrial tachycardia through radiofrequency ablation, with complete symptom resolution at six months follow-up. It emphasizes the importance of timely identification of tachycardiomyopathy as a reversible cause of heart failure.
