摘　　要：目的分析急性冠脉综合征(ACS)患者动态心电图缺血性J波发生状况及诊断意义。方法回顾性分析我院2020年1月至2021年12月收治的72例ACS患者动态心电图资料,包括不稳定心绞痛(UAP)患者(UAP组)与急性心肌梗死(AMI)患者(AMI组),各36例。采集患者有、无心肌缺血发作时的24 h动态心电图检查结果各1次,统计分析UAP组、AMI组患者的动态心电图缺血性J波发生率以及两组有心肌缺血发作时24 h动态心电图出现缺血性J波患者的心律失常发生率。结果UAP组患者有心肌缺血发作时的24 h动态心电图缺血性J波发生率显著高于无心肌缺血发作时,差异具有统计学意义(P<0.05)。AMI组患者有心肌缺血发作时的24 h动态心电图缺血性J波发生率显著高于无心肌缺血发作时,差异具有统计学意义(P<0.05)。UAP组与AMI组有心肌缺血发作时24 h动态心电图出现缺血性J波患者的心律失常发生率无显著差异(P>0.05)。结论动态心电图缺血性J波发生状况对ACS患者具有较高的诊断价值,还可帮助指导医师对ACS患者的室性心律失常提供预防和治疗依据,从而保障患者预后。Objective To analyze the occurrence and diagnostic significance of ischemic J wave in dynamic electrocardiogram in patients with acute coronary syndrome(ACS).Methods The dynamic electrocardiogram data of 72 patients with ACS admitted in our hospital from January 2020 to December 2021 were retrospectively analyzed,including unstable angina pectoris(UAP)patients(UAP group)and acute myocardial infarction(AMI)patients(AMI group),with 36 cases in each group.The results of 24 h dynamic electrocardiogram with and without myocardial ischemia were extracted once respectively.The incidence of ischemic J wave in dynamic electrocardiogram of the UAP group and the AMI group patients and the incidence of arrhythmia in patients with ischemic J wave in 24 h dynamic electrocardiogram during myocardial ischemia were statistically analyzed.Results The incidence of ischemic J wave in 24 h dynamic electrocardiogram during myocardial ischemia in the UAP group was significantly higher than that without myocardial ischemia,and the difference was statistically significant(P<0.05).The incidence of ischemic J wave in 24 h dynamic electrocardiogram during myocardial ischemia in the AMI group was significantly higher than that without myocardial ischemia,and the difference was statistically significant(P<0.05).There was no significant difference in the incidence of arrhythmia in patients with ischemic J wave in 24 h dynamic electrocardiogram between the UAP group and the AMI group(P>0.05).Conclusion The occurrence of ischemic J wave in dynamic electrocardiogram has high diagnostic value for ACS patients,and can also help guide doctors to provide prevention and treatment basis for ventricular arrhythmia in ACS patients,so as to ensure the prognosis of patients.
