长期以来,在欧洲应用ATP治疗阵发性室上性心动过速(PSVT)已取得一定的疗效,新近有人报道,对婴幼儿的PSVT,ATP的疗效优于洋地黄及异搏定,可作为首选药物。电生理学研究表明,ATP可使房室结折返性心动过速(AVNRT)患者房室结中的前向慢通路发生阻滞;使房室折返性心动过速(AVRT)患者的房室结发生阻滞,从而中止折返激动的进行及PSVT的发作。作者对18例PSVT应
For a long time, the application of ATP in the treatment of paroxysmal supraventricular tachycardia (PSVT) has achieved some results, it has been recently reported that infants and young children PSVT, ATP is superior to digitalis and verapamil, as the first choice drug. Electrophysiology studies have shown that ATP blocks the anterior slow pathway in the AV node of atrioventricular nodal reentrant tachycardia (AVNRT) patients; atrioventricular nodules occur in patients with atrioventricular reentrant tachycardia (AVRT) Block, thus stopping the reentry activation and the onset of PSVT. The authors responded to 18 PSVTs
