[Cardiac effect of fenoterol alone or combined with Verapamil (author's transl)].

Two groups each consisting of twelve healthy students received Fenoterol (0,03 microgram/kg/min) alone or in combination with Verapamil (1,2 micrograms/kg/min) intravenously. In both groups, heart rate, arterial blood pressure amplitude and echocardiographically determined left ventricular contractility parameters increased significantly and equally. These results suggest that Verapamil does not counteract the positive chronotropic and inotropic effect of Fenoterol.
