Stress cardiomyopathy (Tako-Tsubo) following radiofrequency ablation in the right ventricular outflow tract

Abstract

A 44-year-old female undergoing radiofrequency ablation in the right ventricular outflow tract for symptomatic, frequent premature ventricular contractions developed stress cardiomyopathy (Tako-Tsubo). Stress cardiomyopathy was probably due to hyperadrenergic state induced by the procedure itself, dobutamine infusion, sympathetic nerve stimulation at the ablation site, and parasympathetic withdrawal with atropine administration. © The Author 2008.
