[Action of papaverine on electromechanical coupling in the rat myocardium].
It was demonstrated in experiments on the rat heart papillary muscle that papaverine (10(-5)-8 X 10(-5) g/ml) suppressed the contractile activity. The drug exerted the cardiac stimulating effect on the atrial auricular. In both cases papaverine smoothed the rhythm-inotropic activity.
