Ventricular monophasic action potentials (MAPs) in patients with ischemic LV dysfunction with (top row) or without (bottom row) events on long-term follow-up. Panels show (A) 79-year-old male, LVEF 29% with appropriate ICD therapy at 400 days; (B) 55-year-old male, LVEF 35% with ICD therapy at 598 days; (C) 70-year-old male, LVEF 25% who died from congestive heart failure at 95 days. Bottom panels show (D) 45-year-old female, LVEF 26%, (E) 63-year-old male, LVEF 40%, (F) 59-year-old male, LVEF 21%, each of whom had no event at > 3 years of follow-up. (G) Expanded MAP upstroke from patient in (F) (black) with dV/dt (red) illustrating signal fidelity.
