摘　　要：目的研究碎裂QRS波（fQRS）与非缺血性扩张型心肌病（NDCM）患者恶性心律失常（MVA）发生的相关性。方法选取2009年2月-2011年8月山东省潍坊市潍坊医学院附属医院住院治疗的NDCM患者57例,通过分析心电图上是否出现fQRS波,分为有fQRS波组33例和无fQRS波组24例,随访（18.9±4.9）个月,比较两组患者的MVA发生率、全因病死率情况。结果两组患者的一般临床资料比较,差异无统计学意义。fQRS波组中发生MVA 15例（45.5%）,无fQRS波组中发生MVA 4例（16.7%）,fQRS波组中MVA的发生率明显高于无fQRS组,差异有统计学意义（P〈0.05）;fQRS波组中病死6例（18.2%）,无fQRS波组中病死3例（12.5%）,fQRS波组病死率高于无fQRS波组,差异无统计学意义（P〉0.05）。结论fQRS对NDCM患者的MVA发生率有一定的预测价值,而与此类患者的全因病死率无明显关联。Objective To study the relationship between fragmented QRS complexes complex（fQRS） and malignant ventricular arrhythmia（MVA） in patients with nonischemic dilated cardiomyopathy（NDCM）. Methods Fifty-seven patients with NDCM in our hospital from February 2009 to August 2011 were analyzed. The ECG characteristics of all patients were retrospectively analyzed.According to their ECG characteristics,all patients were divided into two groups：fQRS group（n = 33） and non-fragmented QRS（non-fQRS） group（n = 24）. The rates of MVA and all-cause mortality in fQRS group and non-fQRS group were followed-up and compared. Results Baseline clinical characteristics of the two groups were comparable without statistical difference. More patients were found with MVA in the fQRS group than in the non-fQRS group（45.5% vs 16.7%,P〈 0.05）. The rate of all-cause mortality was 18.2% in the fQRS group and 12.5% in the non-fQRS group,without statistically significant（P〉 0.05）. Conclusion The fQRS has a predictive value for the occurrence of MVA in patients with NDCM,but there is no significant correlation with all cause mortality.
