摘　　要：目的:分析非ST段抬高心肌梗死(NSTEMI)介入治疗患者心电图表现预测心律失常发生的价值。方法:选择2019年12月-2021年12月某院收治的124例NSTEMI介入治疗患者作为研究对象,均行心电图检查,统计患者介入术后心律失常发生情况;比较发生组与未发生组患者心电图表现及参数,绘制受试者工作特征(ROC)曲线,分析心电图表现对NSTEMI介入治疗患者发生心律失常的预测价值。结果:124例患者中发生心律失常49例(39.52%);发生组患者ST段压低导联数、压低幅度、校正后Tp-Te间期(Tp-Tec)及QT间期(QTc)高于未发生组,差异有统计学意义(P<0.05);绘制ROC曲线得到,ST段压低导联数、压低幅度、Tp-Tec、QTc及联合检查预测NSTEMI介入治疗患者发生心律失常的AUC>0.7,预测价值高。结论:临床开展NSTEMI介入治疗过程中通过积极监测心电图表现、参数能较为准确地预测患者发生心律失常的风险。Objective:To analyze the value of electrocardiogram manifestations for prediction of arrhythmia in patients with interventional therapy of non ST segment elevation myocardial infarction(NSTEMI).Methods:124 patients with interventional therapy of NSTEMI treated in a hospital from December 2019 to December 2021 were prospectively selected as the study subjects,all patients underwent electrocardiogram examination,and the occurrence of arrhythmia in patients after intervention was analyzed;The electrocardiogram manifestations and parameters were compared between the occurrence group and the non occurrence group,and the receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of electrocardiogram manifestations for arrhythmia in NSTEMI patients after interventional therapy.Results:Among 124 patients,49(39.52%)had arrhythmia.The number of ST segment depression leads,depression amplitude,corrected Tp-Te interval(Tp-Tec)and QT interval(QTc)of patients in the occurrence group were significantly higher than those in the non occurrence group,and the difference was statistically significant(P<0.05).The ROC curve was drawn and showed that the AUC values of ST segment depression lead number,depression amplitude,Tp-Tec,QTc and combined examination in predicting arrhythmia in NSTEMI patients after interventional therapy were>0.7,which had high predictive value.Conclusion:Active monitoring of electrocardiogram manifestations and parameters during clinical NSTEMI interventional therapy can accurately predict the risk of arrhythmia in patients.
