摘要(Abstract)：

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.
