ventricular ectopic activity at 24 and 48 h after the onset of posterolateral ischemia was reduced significantly by both intravenous lidocaine ( 1.0-5.0 mg/kg ) and verapamil ( 50.0-500.0 micrograms/kg ) in the vehicle-pretreated dogs , whereas neither antiarrhythmic agent significantly suppressed ventricular ectopy in the digoxin-pretreated dogs .
