143例发病后72小时以内的急性前壁心肌梗塞患者入选,凡有下列情况者已经剔除80岁以上,原有室速,已用过抗心律失常药(不包括β阻滞剂),心源性休克,住院时长时间复苏,严重的心瓣膜异常,已知甲状腺机能异常,任何恶性肿瘤。室速的标准为:连续室早≥5次及心率>100次/分。发病后48小时以内发生者为原发室速,发病后48小时以后发生者为后期室速。观察的终点定为3周,出院病人随访1年。入院后按常规治疗,4小时以内患者进行溶栓疗法。在72小时以内用~(99m)Tc(锝)测定左室射血分数(EF)。
143 cases of acute anterior myocardial infarction within 72 hours after onset of patients were enrolled, where the following conditions have been removed 80 years of age, the original VT, anti-arrhythmic drugs have been used (excluding beta blockers), cardiac Sexual shock, time to hospital recovery, severe heart valve abnormalities, known thyroid dysfunction, any malignancy. VT criteria are as follows: consecutive room ≥ 5 times early and heart rate> 100 beats / min. Occurred within 48 hours after onset of the primary ventricular tachycardia, 48 hours after the onset of late ventricular tachycardia. The end point of the study was set at 3 weeks, followed by 1 year of discharged patients. After admission by conventional treatment, patients within 4 hours of thrombolytic therapy. Left ventricular ejection fraction (EF) was measured with ~ (99m) Tc (technetium) within 72 hours.
