Abstract
Summary
An external mechanical cardiac thump was used to induce a repetitive ventricular response (RVR) in dogs receiving acetyl strophanthidin (AS), a rapidly acting glycoside. The presence of RVR prior to and after termination of AS-in-duced ventricular tachycardia was confirmed by both mechanical and electrical cardiac testing. Mechanically induced RVR may provide a rapid, noninvasive method for assessing the degree of digitalization.
