急性心肌梗死患者48h内出现与未出现碎裂QRS波的预后分析

目的探讨急性心肌梗死患者48h内出现与未出现碎裂QRS波（fQRS）的预后，并分析。方法：收集2012年6月一2015年6月发病并在12h内收入我院的急性心肌梗死患者136例，并均给予急诊冠脉介入治疗，将患者分为两组，按心电图中是否出现碎裂QRS波分组，试验组为出现碎裂QRS波，对照组为未出现碎裂QRS波。对比两组患者住院期间发生心血管事件和心源性死亡的情况。结果：试验组患者在医院住院期间发生心源性休克、心律失常、心源性猝死、心力衰竭、心绞痛以及左室射血分数QVEF）刚氐等情况明显要高于对照组患者，两组患者之间的差异有统计学意义（P〈0．05）。结论：急性心肌梗死患者早48h内出现碎裂ORS波是ST段抬高心肌梗死的高危预警标志，预示患者可能会出现高危心脏，在临床上值得重视。

Objective Within 48 h on patients with acute myocardial infarction （mi） and appears fragmented QRS wave （QRS） f prognosis, and analysis. Methods： Collected during June 2012 to June 2015, the onset and was transferred from the emergency department within 48 h of cardiology hospital 136 cases of patients with acute myocardial infarction （mi）, divided the patients into two groups, according to the electrocardiogram QRS wave group, whether in rapture of QRS wave group to appear ruptura, the control of QRS wave compared two groups of patients did not appear rupture during hospitalization of cardiovascular events and death source sex.Result： Examination m patients with car＆ac shock during hospital be in hospital Arrhythmia. Sudden cardiac death Heart failure Angina pectoris and decreased left ventricular ejection fraction is significantly higher than that of control group patients, the differences between the two groups of patients was statistically significant （P 〈 0.05）.Conclusion： Early in patients with acute myocardial infarction （nil） within 48 h of QRS wave appear rupture is high risk early warning sign of ST segment elevation myocardial infarction （mi）, indicated that patients may be at high risk of a heart, worthy of attention in clinic.
