近年来药理和电生理研究证实,三磷腺苷(ATP)具有强的拟迷走神经作用;使AH间距延长;抑制慢反应纤维的慢Ca~(++)内向流,因而能终止室上性心动过速(SVT),它在体内代谢迅速,血浆清除率约30s,故起效快、失效亦快。临床研究表明它终止SVT的疗效好、安全性较高。且无严重副反应,故本药可作为终止SVT有效药物之 In recent years, pharmacological and electrophysiological studies have confirmed that adenosine triphosphate (ATP) has a strong quasi vagal nerve effect; to extend the distance between the AH; inhibit slow slow fiber Ca (++) inward flow, which can terminate supraventricular heart beating Over-speed (SVT), it is rapidly metabolized in the body, the plasma clearance rate of about 30s, so fast onset, failure is also fast. Clinical studies have shown that it is effective and safe to discontinue SVT. And no serious side effects, so the drug can be used as an effective SVT termination of the drug
