Dissociated late potentials during sinus rhythm after radiofrequency ablation in a patient with postinfarction ventricular tachycardia

A 72-year-old man with ischemic cardiomyopathy was admitted for the treatment of ventricular tachycardia (VT). Because his VT was poorly tolerated hemodynamically, substrate mapping was performed. The map revealed the presence of low-voltage areas in the inferolateral wall of the LV. Late potentials...
