A previous study found that the electrophysiological response to ischemia is altered in hypertrophic myocardium, resulting in prolonged transmural activation time (TAT) associated with induction of sustained monomorphic ventricular tachycardia. This study investigated the role of hemodynamics in modulating TAT and the cycle length of induced ventricular tachycardia (VT) in dogs with left ventricular hypertrophy (LVH).
