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 characteristics of acute miocardial infarction combined ST segment elevation with ischemic J wave in the super acute period of acute myocardial infarction,in order to evaluate the clinical value of ischemic J wave on the prognosis of acute myocardial infarction.Methods:88 acute myocardial infarction patients with ST segment elevation were selected from April 2010 to January 2011.All the patients were divided into J wave group and non J wave group according to the results of ECG shown,and the correlation between ischemic J wave and arrhythmia was analyzed.Results:The incidence of ventricular arrhythmias in the J wave group was significantly higher than that in the non J wave,and the difference was statistically significant(χ2=15.660,P=0.000).The form varied,and the most common is the short formation ventricular Heartbeat tachycardia (30%),followed by ventricular fibrillation(12.5%);J wave group of AV block in 5 cases,non J wave group atrioventricular block in 0 cases,the difference was statistically significant between two groups(P<0.05). Conclusion: Ischemic J wave is a new index for sudden cardiac death early warning.
