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.
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.
