英卡胺口服能延长房室结和希氏束传导时间和房、室及附加径路的不应期.本文总结33例长期口服英卡胺治疗室上性心动过速伴预激综合征的电生理学和临床效果. 方法:33例慢性复发性室上性心动过速伴预激综合征患者,在停用心脏活性药物达5倍半衰期后进行电生理学对照研究.对照研究结束后口服英卡胺25毫克,每6小时一次,每天增加40～100毫克, Icazacil orally can prolong the atrioventricular node and His bundle conduction time and room, room and additional refractory period of pathology.This article summarizes 33 cases of long-term oral administration of enka amine supraventricular tachycardia with pre-excitation syndrome electrophysiology And clinical effect.Methods: 33 patients with chronic recurrent supraventricular tachycardia and pre-excitation syndrome were performed electrophysiological control study after stopping the cardiorespiratory activity for 5 times of half life.After the control study, Mg, once every 6 hours, an increase of 40 to 100 mg per day,
