the arterial blood pressure was between 19 mmhg ( diastolic ) and 27 mmhg ( systolic ) higher in the oxyfedrine treated animals , but there were no differences between the two groups with regard to cardiac output , left ventricular dp/dt max , heart rate or systolic ejection time.2 in cats similarly treated with propranolol ( 4 mg/kg ) there was a slight ( 12 % ) , but significant , reduction in cardiac output.3 isoprenaline dose-response curves were shifted to the right in the cats administered oxyfedrine as well as in those administered propranolol .
