急性心肌梗死患者心电图J波与心律失常的关系

THE RELATIONSHIP BETWEEN J WAVE OF EKG AND ARRHYTHMIA IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION

目的探讨急性心肌梗死患者心电图J波发生的临床特点及与心律失常的关系。方法收集172例急性心肌梗死患者资料,根据心电图结果分为J波组和非J波组,分析J波发生的临床特征,并比较二组患者心律失常发生情况。结果共23例患者出现J波,J波发生率为13.4%,J波组与非J波组室性心动过速、恶性心律失常发生率分别为44.0%比24.16%、43.48%比20.81%,各组比较差异有统计学意义(P均<0.05)。结论急性心肌梗死患者心电图J波发生率较高,伴有J波的患者更易发生恶性心律失常。一旦出现,要加强心电监护,随时准备电复律。

Objective To investigate the clinical characteristics of J wave of the patients with acute myocardial infarction(AMI),and to study the relationship between J wave and arrhythmia.Methods Totally 172 patients with AMI were divided into J wave group and non-J wave group according to the electrocardiogram.The clinical characteristics of J wave were analyzed,and the occurrence of arrhythmia was compared between the two groups.Results A total of 23 patients were observed J wave,The incidence of J wave was 13.4%.The J wave group had higher incidence of malignant arrhythmia than the non-J wave group(P<0.05).Conclusions The incidence of J wave in the patients with AMI is high.These patients with J wave are more likely suffer from malignant arrhythmia,and cardiac monitoring should be exerted for them.
