目的:探讨急性ST段抬高性心肌梗死伴缺血性J波在急性心肌梗死(AMI)超急期的临床特点,评价缺血性J波对急性心肌梗死预后的临床价值。方法:2010年4月-2011年1月收治急性ST段抬高性心肌梗死患者88例,按心电图结果所示有无J波,分为J波组和非J波组,分析缺血性J波与发生心律失常之间的相关性。结果:J波组的室性心律失常的发生率较非J波组明显增高,差异具有统计学意义(χ2=15.660,P=0.000),而且形态多变,最常见的是短阵型室性心动过速(30.0%),其次为心室颤动(12.5%);J波组出现房室传导阻滞5例,非J波组房室传导阻滞0,两组比较,P<0.05,差异具有统计学意义。结论:缺血性J波是心源性猝死预警的新指标。
Objective: To investigate the clinical features of acute ST-segment elevation myocardial infarction with ischemic J-wave in patients with acute myocardial infarction (AMI) and to evaluate the clinical value of ischemic J wave in the prognosis of acute myocardial infarction. Methods: From April 2010 to January 2011, 88 patients with acute ST-segment elevation myocardial infarction were enrolled. According to the results of electrocardiogram (ECG), there was no J wave, which was divided into J wave group and non-J wave group. The incidence of ischemic J Correlation between wave and arrhythmia. Results: The incidence of ventricular arrhythmia in J wave group was significantly higher than that in non-J wave group, the difference was statistically significant (χ2 = 15.660, P = 0.000), and the morphology was varied. The most common was ventricular arrhythmia (30.0%), followed by ventricular fibrillation (12.5%); J wave group of 5 cases of atrioventricular block, non-J wave group atrioventricular block 0, the two groups, P <0.05, the difference was statistically Significance of learning. Conclusion: Ischemic J wave is a new indicator of early warning of sudden cardiac death.
