摘　　要：目的:分析急性冠脉综合征(ACS)患者QRS波群时限与恶性心律失常的关系。方法:150例ACS患者根据QRS波群时限分为QRS波群时限≤110 ms组(A组)、110 ms<~<120 ms组(B组)、QRS波群时限≥120 ms组(C组),对所有患者行24 h动态心电图检查,比较3组患者中不同LOWN分级(Ⅰ级、Ⅱ级、Ⅲ级、ⅣA级、ⅣB级及Ⅴ级)患者百分比,检测心率变异性(HRV)指标[相邻NN之差>50 ms的个数占总窦性心搏个数的百分比(p NN50)、相邻RR间期差值的均方根(RMSSD)、全部窦性心搏RR间期的标准差(SDNN)、RR间期平均值标准差(SDANN)及三角指数]变化。结果:A、B两组ACS患者LOWN分级及HRV指标比较,差异无统计学意义(P>0.05);C组ACS患者LOWN分级Ⅲ、ⅣA、ⅣB级的比例高于A组和B组,HRV各项指标低于A组和B组,差异有统计学意义(P<0.05)。结论:急性冠脉综合征患者QRS波群时限与恶性心律失常发生概率有关。Objective： To analyze the correlation between QRS duration and malignant arrhythmia in patients with acute coronary syndromes（ ACS）. Methods： 150 patients with ACS admitted to hospital from June 2015 to June 2017 were selected as the subjects. The patients were divided into Group A with QRS duration≤110 ms,Group B with QRS duration 110 ms ~ 120 ms,and Group C with QRS duration ≥120 ms. A total of 24 hours of ambulatory electrocardiogram were performed in the three groups. The Lown grade index and heart rate variability index were analyzed. Results： There was no significant difference in Lown grade and HRV indexes between Group A and Group B. The ratio of Lown grade Ⅲ,Ⅳ. A and Ⅳ. B in Group C was significantly higher than that in Group A and B,and HRV indexes of Group C decreased significantly then those of Groups A and B（ P〈0. 05）. Conclusion： The time of QRS wave in patients with ACS is significantly correlated with the probability of occurrence of malignant arrhythmia.
