Response to pacing at sites of isolated diastolic potentials during ventricular tachycardia in patients with previous myocardial infarction.


OBJECTIVES The goal of this study was to determine whether isolated diastolic potentials (IDPs) recorded during ventricular tachycardia (VT) are generated in zones of slow conduction and whether the arcs of block that bound these zones of slow conduction are functional or anatomic in nature. BACKGROUND No previous studies have systematically investigated… (More)
