摘要：
The chronotropic response of rat atria to beta adrenergic stimulation required higher concentrations of agonist in the presence of adenosine. This anti beta-adrenergic effect could attenuate the tachycardia induced by the increased sympathetic tone during cardiac ischemia. The sensitivity to alpha adrenergic stimulation did not change in the presence of adenosine.
