目的:探讨急性心肌梗死(AMI)患者QRS波及其时限与室性心律失常的关系。方法:回顾分析惠州市中心人民医院2014年10月至2016年10月收治的102例AMI患者临床资料,根据患者是否出现室性心律失常分为A组与B组,其中A组(64例)为室性心律失常者,B组(38例)未发生室性心律失常。比较两组患者一般资料,分析患者QRS波形与时限对室性心律失常的影响。结果:两组性别、年龄及既往史等一般资料比较,差异无统计学意义(P>0.05),但A组梗死部位、出现碎裂QRS(fQRS)波、QRS波时限、Killip分级均与B组存在显著差异,并对上述因素进行多因素Logistic回归分析,显示fQRS、QRS波时限及Killip分级均是室性心律失常的独立危险因素。结论:临床治疗AMI时需密切关注患者心电图表现,尤其是fQRS波出现,及QRS波时限>110ms者,积极预防室性心律失常发生。
Objective: To investigate the relationship between QRS duration and ventricular arrhythmia in patients with acute myocardial infarction (AMI). Methods: A retrospective analysis of 102 patients with AMI admitted to Huizhou Central People’s Hospital from October 2014 to October 2016 was divided into group A and group B according to whether patients had ventricular arrhythmia. Group A (64 cases) Ventricular arrhythmias, group B (38 cases) did not occur ventricular arrhythmia. The general data of two groups were compared to analyze the effect of QRS waveform and time limit on ventricular arrhythmia. Results: There was no significant difference between the two groups in general information such as sex, age and past history (P> 0.05). However, in group A, the fissure QRS (fQRS) wave, QRS wave duration, There were significant differences between the two groups. Multivariate Logistic regression analysis showed that fQRS, QRS wave duration and Killip classification were both independent risk factors for ventricular arrhythmia. Conclusion: The clinical manifestation of AMI needs to pay close attention to the electrocardiogram (ECG), especially fQRS wave and QRS wave duration> 110ms to prevent ventricular arrhythmia.
