摘要
本文以随机分组的方法,用食管心电图比较异搏定、心律平和三磷酸腺苷(ATP)终止室上性心动过速的疗效及转复过程,并对其作用机制进行初步探讨。对象及方法室上性心动过速选择持续发作10分钟以上的患者(包括自发和食管调搏诱发者)。所有患者均患有房室结折返性心动过速(AVNRT)
Sixty patients with sustained supravcntricular tachycardia (SVT)were treated with intravenous verapamil., propafenone, or ATP on a randomized basis. Esophageal electrocar-diogram was used to monitor the course of conversion and drug effect, especially the site of termination. Propafenone was effective in terminating SVT(75%)with very smooth course, whereas a little lower conversion rate was shown with verapamil (70%). Although the successful rate is very high in ATP group (100%), this drug should be used with caution because of the unstable course after conversion and significant high incidence of side effect.
