对丙胺苯丙酮静脉注射后仍能诱发出室上性心动过速(SVT)的15例患者,再予静脉注射维拉帕米,应用食管调搏在用药前后作电生理测定。结果表明,两药合用能使房室结或慢径路不应期显著延长(P<0.01),全部病例均不再诱发出 SVT。提示两药联合静脉注射对难治性 SVT 可能是一种有效的疗法。
Fifteen patients who were still able to induce supraventricular tachycardia (SVT) after intravenous injection of propanic propanone were treated with intravenous injection of verapamil. Electro-physiological measurements were performed before and after administration of esophageal pacing. The results showed that the combination of two drugs can make atrioventricular node or slow pathway refractory period was significantly prolonged (P <0.01), all cases no longer induced SVT. Prompt two drugs combined intravenous injection of refractory SVT may be an effective therapy.
