Receptor mechanisms involved in the 5-HT-induced inotropic action in the rat isolated atrium
1. The effects of 5-hydroxytryptamine (5-HT) in rat cardiac preparations were studied. 5-HT up to 10 μM failed to affect contractility in papillary muscles. However, in electrically driven (1 Hz) left atria 5-HT exerted a positive inotropic effect that started at 1 μM and attained its maximum at 10 ...
