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。
Objective: To investigate the effects of adenosine triphosphate (ATP) on other cardiac arrhythmias during the recovery of emergency patients with paroxysmal supraventricular tachycardia (PSVT). Methods: From January 2000 to May 2002 in our department by intravenous bolus ATP transfusion 124 cases of PSVT patients. Throughout the observation and record of patients with 12-lead ECG, blood pressure and clinical manifestations. Results: In 124 patients with ventricular ectopic rhythm, PSVT accounted for 42%, of which about 1/2 of patients with right bundle branch block, indicating that the impulse originated in the lower part of the left ventricular septum. ATP-induced ventricular arrhythmias are transient and self-terminating Conclusion: The incidence of ventricular arrhythmias during IV bolus ATP transfused emergency PSVT is high without further intervention. For elderly patients with impaired sinus node function or atrioventricular block, or are using β-blockers and those with severe organic heart disease, intravenous ATP should be considered contraindications.
