根据三磷酸腺苷(ATP)对心脏有负性变时性及负性传导作用的机理,我院从1983年12月至1990年12月应用ATP快速静脉注射治疗阵发性室上性心动过速(PSVT),取得满意疗效,现报告如下。 1 临床资料 1.1 一般资料本组47例,男32例,女15例;年龄24～76岁;其中不稳定性心绞痛6例,稳定性心绞痛1例,高心病6例,风心病5例,扩张型心肌病3例,预激综合征1例;以上心功能Ⅰ级19例,心功能Ⅱ级3例;其余25例为未查明有器质性心脏病患者。 1.2 心电图诊断标准心室率150～250次/min、P波正向或倒置或隐没在其前的T波中、R-R间期绝对匀齐,QRS形态呈室上型。 1.3 治疗方法与结果 27例(无器质性心脏病25例,器质性心脏病心功能Ⅰ级1例,心功能Ⅱ级1例)快速静脉注射ATP 15～20mg(5s内推完),有24例
According to ATP (adenosine triphosphate) on the heart of the negative time-varying and negative conduction mechanism, our hospital from December 1983 to December 1990 ATP rapid intravenous injection of paroxysmal supraventricular tachycardia (PSVT ), Achieved satisfactory results, are as follows. 1 Clinical data 1.1 General Information The group of 47 patients, 32 males and 15 females; aged 24 to 76 years; of which 6 cases of unstable angina, stable angina in 1 case, 6 cases of heart disease, rheumatic disease in 5 cases, expansion 3 cases of cardiomyopathy, and 1 case of pre-excitation syndrome. Among them, 19 cases were grade Ⅰ with cardiac function and 3 cases with cardiac function with grade Ⅱ. The remaining 25 cases were those without organic heart disease. 1.2 ECG diagnostic criteria ventricular rate 150 ~ 250 beats / min, P wave forward or inversion or hidden in the T wave before, R-R interval is absolutely homogeneous, QRS morphology was supratentorial. 1.3 Treatment Methods and Results 27 cases (25 cases without organic heart disease, 1 case with organic heart disease grade I, and 1 case with cardiac function grade II) were given intravenous injection of 15 ~ 20mg ATP (5s) There are 24 cases
