摘　　要：目的:研究急性冠脉综合征QRS波时限与恶性心律失常相关性。方法:本研究选取了惠州市中心人民医院于2015年6月-2017年6月收治的130例急性冠脉综合征患者作为研究对象,根据患者的QRS波时限将患者分为低水平组、中水平组和高水平组,对比三组患者的动态心电图检测指标。结果:患者的LOWN分级结果显示三组患者的Ⅱ级和Ⅴ级患者人数相比差异无统计学意义(P>0.05),但高水平组患者的Ⅳ级和Ⅲ级患者人数均明显高于低水平组和中水平组(P<0.05),Ⅰ级患者人数显著低于低水平组和中水平组(P<0.05),低水平组和中水平组的Ⅰ级、Ⅳ级和Ⅲ级患者人数相比差异无统计学意义(P>0.05);高水平组患者的各项心率变异性指标均明显低于低水平组和中水平组(P<0.05),但低水平组和中水平组的心率变异性指标相比差异均无统计学意义(P>0.05)。结论:急性冠脉综合征患者的QRS波时限与恶性心理失常存在显著的相关性,QRS波时限水平越高患者的恶性心律失常发生率越高。Objective： To study the correlation between QRS duration and malignant arrhythmia in acute coronary syndrome. Methods： This study selected the Huizhou Central People＇s Hospitalfrom June 2015 to June 2017 treated 130 cases of patients with acute coronary syndrome as the research object, according to the patient＇s level of QRS wave time divided the patients into low group, middle level and high level group, compared with dynamic electrocardiogram examination indexes of three groups of patients. Results： The LOWN grading results of patients showed that there was no significant difference in the number of patients with grade Ⅱ and Ⅴ in the three groups （P〉0.05） , but the number of patients in grade Ⅳ and Ⅲ in the high-level group was significantly higher than the low level group. In the middle-level group （P〈0.05）, the number of patients in the grade I group was significantly lower than that in the low-level group and the middle-level group （P〈0.05）. The number of patients in the low-level group and the middle-level group was comparable to that of the patients in the grade I , IV, and Ⅲ. The difference was not statistically significant （P〉0.05） ; the heart rate variability of patients in the high-level group were significantly lower than those in the low-level group and the middle-level group （P〈0.05）, but the heart rate variability in the low-level group and the middle-level group. There was no significant difference in sex index （P〉0.05）. Conclusion： QRS duration in patients with acute coronary syndrome is significantly associated with malignancy. The higher the QRS duration is, the higher the incidence of malignant arrhythmias is.
