propranolol ( 2.0-4.0 mg/kg ) had the same effect in each of four dogs.3 both tiprenolol ( 4.0-8.0 mg/kg ) and propranolol ( 4.0 mg/kg ) increased the frequency of sinus beats and reduced the ventricular rate in dogs with ventricular tachycardia 20-44 h after ligation of a coronary artery.4 practolol ( 0.5-16.0 mg/kg ) did not reduce the ventricular rate or increase the frequency of sinus beats in dogs with ventricular tachycardia after ligation of a coronary artery.5 in dogs with ouabain-induced ventricular tachycardia mean arterial pressure was reduced after the administration of tiprenolol ( 0.5-8.0 mg/kg ) or propranolol ( 4.0-8.0 mg/kg ) .
