目的评价静脉注射胺碘酮(可达龙)治疗宽QRS心动过速的疗效及安全性。方法急诊科收治宽QRS心动过速患者50例,其中34例伴有不同程度的心力衰竭,9例就诊时有严重低血压。患者均接受静脉注射可达龙治疗,根据心律失常转复为窦性心律、未转复但心率减慢和心律失常未纠正且心率未减慢而分别评为显效、有效和无效。同时分析用药前后的血压、心率及药物的不良反应,并评价心力衰竭有无加重。结果50例患者中显效率62.0%,有效率28.0%,无效率10.0%,无心力衰竭加重,无严重的药物不良反应发生。结论宽QRS心动过速特别是合并心功能不全的患者,静脉注射可达龙是有效和安全的。
Objective To evaluate the efficacy and safety of intravenous amiodarone (up to dragon) in the treatment of wide QRS tachycardia. Methods A total of 50 patients with wide QRS tachycardia admitted to the emergency department were enrolled. Among them, 34 patients had different degrees of heart failure and 9 patients had severe hypotension. Patients received intravenous dalteparin, converted to sinus rhythm according to arrhythmia, did not recuperate, but their heart rate was slowed and their arrhythmia was uncorrected and their heart rate did not slow down. The patients were evaluated as effective, effective and ineffective. At the same time analysis of blood pressure before and after treatment, heart rate and adverse drug reactions, and evaluation of heart failure with or without aggravating. Results In 50 patients, the effective rate was 62.0%, the effective rate was 28.0%, the ineffective rate was 10.0%. No heart failure was aggravated. No serious adverse drug reaction occurred. Conclusion Wide QRS tachycardia, especially in patients with cardiac insufficiency, intravenous reachable dragon is effective and safe.
