冠脉造影慢血流现象与动态心电图表现的对比研究

Comparison of slow blood flow phenomenon on coronary arteriogram with findings on dynamic electrocardiogram

目的观察冠状动脉造影慢血流现象与动态心电图表现的关系。方法选择我院2006年1月-2009年5月因胸痛行冠状动脉造影发现冠状动脉慢血流的病例43例,同时选择冠状动脉造影正常病例30例做对照。冠状动脉造影术后次日行动态心电图检查并分析结果。结果26例患者(60.5%)出现一过性定位相关的ST段压低≥0.2mV心电图改变;32例患者(67.4%)出现一过性T波改变(包括与静息心电图比较T波双向或倒置);21例患者(48.8%)出现频发室早或短阵室速。与对照组比较,慢血流组室早或短阵室速的发生率较高(P<0.01)。结论冠状动脉慢血流现象累及支数与动态心电图发现的频发室早或短阵室速相关。

Objective To investigate the relation between slow blood flow phenomenon on coronary arteriogram and findings on dynamic electrocardiogram. Methods Forty-three patients with chest pain admitted to our hospital underwent coronary arteriography in January 2006-May 2009 （CAG）, which showed slow blood flow phenomenon. Thirty patients with normal CAG served as controls. Dynamic electrocardiography was performed the day after coronary arteriography. The results were analyzed. Results Of the 43 patients, 26（60.5%） showed depression in ST segment, 32（67.4%） showed alterations in T wave, and 21（48.8%） showed frequent ventricular premature or non-sustained ventricular tachycardia. Frequent ventricular premature or non-sustained ventricular tachycardia was more frequent in patients with abnormal CAG than in those with normal CAG（P〈0.01）. Conclusion The number of blood vessels involved in coronary slow flow phenomenon is related with frequent ventricular premature or non-sustained ventricular tachycardia.
