1 the effects of tolamolol on haemodynamics and myocardial contractility were investigated in two groups of six patients undergoing diagnostic cardiac catheterization.2 the intravenous administration of tolamolol ( 0.15 mg/kg ) produced a significant fall in heart rate from a control value ( 87 +/- 7 to 62 +/- 3 beats/min ) 5 min after administration and a concomitant fall in cardiac output from 4.7 +/- 0.9 to 3.5 +/- 0.8 litres/minute .
