ST抬高急性心肌梗死J波引起心律失常的分析

Analysis of arrhythmias caused by J waves in ST elevation acute myocardial infarction

目的探讨ST抬高急性心肌梗死J波引起心律失常的临床特征。方法60例ST段抬高急性心肌梗死患者,均行心电图检查,对其检查结果进行回顾性分析。结果60例患者中15例出现缺血性J波,其中室性心律失常9例,无室性心律失常6例;45例患者没有出现J波状况,其中室性心律失常14例,无室性心律失常31例;J波组室性心律失常发生率60.0%高于无J波组的31.1%,差异有统计学意义(P<0.05)。结论ST段抬高型心肌梗死超急性期心电图改变比较明显,出现J波引起室性心律失常明显高于无J波引起室性心律失常患者,并且缺血程度重于无J波引起室性心律失常患者,掌握其特点利于对病情评估,可预防严重并发症,有着重要的临床使用价值。

Objective To analyze the clinical features of arrhythmias caused by J waves in ST elevation acute myocardial infarction.Methods All 60 patients with ST-segment elevation acute myocardial infarction underwent electrocardiography,and their findings were analyzed retrospectively.Results Among the 60 patients,15 cases had ischemic J waves,including 9 cases with ventricular arrhythmias and 6 cases without ventricular arrhythmias;45 cases had no J waves,including 14 cases with ventricular arrhythmias and 31 cases without ventricular arrhythmias.The incidence of ventricular arrhythmia 60.0%in the J-wave group was higher than 31.1%in the no-J-wave group,and the difference was statistically significant(P<0.05).Conclusion The electrocardiogram changes are obvious in the hyperacute stage of ST segment elevation myocardial infarction.The arrhythmia caused by J wave is significantly higher than that caused by no J wave,and the degree of ischemia is more serious than that in patients without J wave.Mastering its characteristics is conducive to the evaluation of the disease and the prevention of serious complications,which has important clinical value.
