Abstract:
It was found that Ginsenoside B (GSB) could reduce the myocardial systolic power and frequency of the isolated atrium of guinea pigs in a concentration-dependent way, and obviously prolong the functional refractory period of the left atrium. GSB could competitively antagonize the positive inotropic action of Iso, and non-competitively antagonize the positive inotropic action of CaCl2 on the isolated right atrium of guinea pigs.
