摘　　要：本文用食管心房搏法诱发房室折返性心动过速（ＡＶＲＴ）７６例次，对比观察了ＡＴＰ１０、２０、３０ｍｇ和５、１０ｓ给药速度终止ＡＶＲＴ的疗效和终止特点。结果表明：①ＡＴＰ终止ＡＶＲＴ的疗效与剂量有关，１０ｍｇ有效率为５７．１４％，２０ｍｇ和３０ｍｇ均达１００％；对窦房结和房室结的抑制作用亦随剂量增加而加大。②ＡＴＰ静注速度５ｓ与１０ｓ疗效无显著差异。ＡＴＰ终止ＡＶＲＴ前均出现ＲＲ和Ｐ－Ｒ间期逐渐延长，至Ｐ后ＱＲＳ脱漏终止心动过速。The effects of ATP on termination of atrio-ventricular reentrant tachycardia(AVRT) in 76 cases induced by esophageal pacing were observed. 10, 20 and 30 mg ATP were intravenously administered within 5 and 10 s, respectively.The results showed that(l)the effects of ATP on termination of AVRT were dose-dependent. The effective rate was 57.14%when 10 mg ATP was given and 100%at the dose of 20 and 30 mg.(2)No signficant difference was found when intravenous injection was within 5s and l0s. (3) It was shown that P-R and RR intervals were prolonged until the R wave disappeared, which indicated the termination of AVRT.
