摘要
目的:探讨三磷酸腺苷(ATP)在转复急诊阵发性室上性心动过速(PSVT)过程中出现其他心律失常,及用药中的注意事项。方法:对2000年1月至2002年5月在我科经静脉推注ATP转复的124例PSVT患者。全程观察和记录患者的12导心电图、血压及临床表现。结果:124例PSVT中出现室性异位节律者占42%,其中约1/2患者出现右束支传导阻滞,表明冲动起源于左室间隔下部。ATP诱导的室性心律失常是暂时的,可自行终止结论:静脉推注ATP转复急诊PSVT过程中室性心律失常的发生率较高,无需进一步干预。对高年患者已存在窦房结功能受损或房室传导阻滞,或正使用β-受体阻滞剂以及有严重器质性心脏病者,应视为静脉注射ATP的禁忌证。
Objecttive: To explore arrhythmia induced by adenosine triphosphate (ATP) in the course of cardioversion in patients with paroxysmal supravenlricular tachycardia( PSVT) , and attentive items during administration of ATP. Methods; 124 patients with PSVT were treated with ATP in our hospital from Jan,2000 to May,2002. 12 leads electrocardiograph,blood pressure and clinical situation were recorded during the course of cardioversion. Results; Ventricular ectopic rhythm occurred in 42 percent of all the 124 patients with PSVT,right bundle branch block( RBBB) occurred in about half patients among them, this made it clear that the impulse originated in the bottom of left interventricular septum. Ventricular arrhythmia induced by ATP was temporary and terminated by itself. Conclusion;The incidences of ventricular arrhythmia was high in the course of cardioversion in patients with PSVT by injection of ATP through intravenous route. Although further intervention was not necessary, we regarded that old patients and damaged sinus,or atrioventricular block as well as severe organic cardiac diseases are contraindicated.
