心电图碎裂QRS波预测急性心肌梗死室性心律失常的价值探讨

To explore the value of fragmented QRS to predict ventricular arrhythmic events in patients with a- cute myocardial infarction

目的探讨心电图ST段抬高型急性心肌梗死患者碎裂QRS波（fragmented QRS com-plex，fQRS）预测急性心肌梗死室性心律失常的价值。方法在急性心肌梗死后8周左右对每一位研究对象均进行常规心电图和动态心电图检查及生化标志物检测，根据常规心电图fQRs的有无，将研究对象分为fQRS组和非fQRs组，分别统计室性心律失常的发生率。结果fQRs组24h室性早搏的发生数明显高于非fQRs组（3140±555 vs 1226±142，P〈0．01），复杂室性心律失常的发生率明显高于非fQRS组（34．4％VS10．7％，P〈0．05）。结论心电图12导联fQRS波可能可预测ST段抬高型急性心肌梗死患者室性心律失常事件的发生。

Objective The purpose of this study was to determine whether fQRS is associated with increased ventricular arrhythmic event in patients with Acute ST- elevation Myocardial Infarction. Methods 12-lead ECG, 24h-Hoher monitoring and biochemical markers detection were performed in sixty cases with acute ST-elevation myocardial infarction, which were divided into two groups [ fQRS group and non- fQRS group] according to Fragmented QRS （fQRS） on 12-lead ECG. Then ventricular arrhythmic events were analyzed. Results Ventricular premature beats （24 h, 3140 ± 555 vs 1226 ± 142, P 〈 0. 01 ） and the incidence of complex ventricular arrhythmic events （34. 4% vs 10. 7%, P 〈 0. 05 ） in fQRS group were significantly higher than that in non- fQRS group. Conclusions Fragmented QRS may be used to predict ventrieular arrhythmie events in patients with acute ST- elevation myocardial infarction.
