静注心律平治疗室上性心动过速

Intravenous Propafenone for Supraventricular Tachycardia

静注心律平２ｍｇ／ｋｇ治疗室上性心动过速（ＳＶＴ）４７例，其中包括房室折返型心动过速（ＡＶＲＴ）３２例，房室结内折返型心动过速（ＡＶＮＲＴ）１０例，房内折返型心动过速（ＩＡＲＴ）４例，自律性房速（ＡＡＴ）１例，有效率６７％。静注心律平前后进行心电图和经食管心房调搏（ＴＥＡＰ）检查，结果表明心律平对房室传导系统和房室旁路的传导有抑制作用，并延长心房、房室结和旁道有效不应期。

To 47 patients with SVT, including AVRT(32), AVNRT (10),IART (4)and AAT (1), propafenone 2mg/kg. was given intravenously over 10 minutes. The effective rate of propafenone in SVT was 67%. ECG and TEAP were taken pre-and post-medication.The result showed that antiarrhythmic effects observed due to inhibition of conduction on special conduction tissues of the heart as well as bypass tract, also prolongation of ERPA,ERPAVN and ERPAP.
