急性心肌梗死患者J波与室性心动过速的关系

Relationship between J wave and ventricular tachycardia in patients with acute myocardial infarction

目的:探讨急性心肌梗死伴J波时对室性心动过速的影响。方法:回顾性分析113例急性心肌梗死患者发病6h内第1次心电图改变,记录有无J波,分为J波组43例,无J波组70例;并进行静态心电监护,对两组室性心动过速的发生情况进行比较。结果:J波组室性心动过速的发生率高于无J波组(P<0.05)。结论:伴有J波的急性心肌梗死患者室性心动过速的发生率增加,提示急性心肌梗死患者伴J波时心电更加不稳定。

Objective：To observe the influence of J wave on ventricular tachycardia in patients with acute myocardial infarction.Methods：The electrocardiogram of 113 patients who were hospitalized less than six hours was retrospectively analyzed.The patients were divided into J wave group（43 cases）and non J wave group（70 cases）.The static electrocardiogram of the two groups was recorded and the ventricular tachycardia rates were compared.Results：Ventricular tachycardia rates were significantly higher in the J wave group than in the non J wave group（P〈0.05）.Conclusions：The ventricular tachycardia rate is increased in patients with acute myocardial infarction accompanied by J ware,indicating that their electrocardiogram is more likely to be unstable.
