急性心肌梗死患者碎裂QRS波群分析

Analysis of fragmented QRS complex in patients with acute myocardial infarction

目的探讨心电图碎裂QRS波群(fragmented QRS complex,fQRS)在急性心肌梗死(AMI)诊断中的应用价值。方法选择162例急性心肌梗死患者,根据是否发生fQRS波群将其分为fQRS组和无fQRS组,比较两组患者心肌梗死后心绞痛、心律失常、ST段抬高导联数及住院病死率。结果比较两组患者梗死后心绞痛、心律失常、ST段抬高导联数、死亡率,差异均有统计学意义(P<0.05)。结论 QRS波群的发生与心肌梗死患者的预后密切相关。

Objective To explore the clinical value of fragmented QRS complex in diagnosis of acute myocardial infarction (AMI). Methods One hundred and sixty-two patients with AMI were enrolled in the study and were divided into two groups, fQRS and non-fQRS, according to the presence of fQRS. Incidence rates of reoccur angina, arrhythmia, leads of ST-segment elevation, hospital mortality were compared between two groups. Results The incidence rates of reoccur angina, arrhythmia, leads of ST-segment elevation, hospital mortality in fQRS group were significantly higher than those of non-fQRS group (P&lt;0.05). Conclusion The presence of fragmented QRS complex may be involved in the prognosis of patients with myocardial infarction.
