摘　　要：目的观察多巴胺对阵发性室上性心动过速的转复效果。方法 43例资料完整明确诊断PSVT伴低血压患者(拒绝电复律),经物理治疗失败后给予多巴胺20 mg(不稀释),10 s静脉匀速注射,观察成功率,转复时间,转复前、转复后即刻、5 min、1 h患者心率、血压变化,PSVT终止时合并症。结果成功率93.02%,其中有21例在静脉注射盐酸多巴胺注射液后立即转复为窦性心律,19例在30 s～3.9 min转复为窦性心律,3例失败。成功患者无血压大于140/90 mmHg者及心率每分钟小于60次者。终止PSVT时8例出现恶心呕吐症状,14例胸闷、10例乏力、8例无特殊不适。但是均为一过性发作,未经处理自行缓解。结论多巴胺可作为终止低血压伴室上性心动过速患者的转复药物。Objective To observe the therapeutic efficacy of Dopamine in PSVT patients with hypotension. Methods 43 PSVT patients with hypotension who failed to recover after physical therapeutics and electrical conversion was denied were admitted. 20 mg Dopamine was injected by intravascular within 10 second, before the observation of recovery rate, time to recovery, heart rate and blood pressure changes before recovery ,5 minutes after injecton of Dopamine, and 1 hour after recovery and complicatons of recovery. Results The re- covery rate was 93.02%. 21 patients recover to sinus arrhythmia right after injection of Dopamine, 19 patients recover within 3 second to 3.9 min,3 patients failed recovery. In recovery patients, no blood pressure was higher than 140/90 mmHg and no heart rate was lower than 60 bpm, when PSVT was stopped,8 patients were accompanied with nausea and vomiting, 14 patients chest distress, 10 patients de- bility and 8 patients no specific discomfort. Conclusion Dopamine can be used to terminate PSVT with hypotension safely when electro- version is denied.
