心电图T波峰末(Tp-Te)间期在心肌梗死中的诊断价值

The diagnostic value of T wave crest(Tp-Te)interval in the diagnosis of patients with myocardial infarction

目的:探讨心电图T波峰末(Tp-Te)间期在心脏疾病中的诊断价值。方法:收治心肌梗死患者120例,均进行动态心电图监测,并分为心律失常组90例(室速组65例,室早组25例),非心律失常组30例。根据超声心动图分为重构组42例和非重构组78例。根据临床结局的不同分为心血管事件组15例和非心血管事件组105例。比较各组间的Tp-Te、Tp-Te离散度。结果:各组间的Tp-Te、Tp-Te离散度差异均有统计学意义(P<0.05)。结论:Tp-Te间期对心肌梗死后心律失常及其预后情况有一定的预测作用。

Objective:To investigate the diagnostic value of T wave crest(Tp-Te)interval in the diagnosis of patients with heart disease.Methods:120 patients with myocardial infarction were selected,all patients underwent ambulatory ECG monitoring,they were divided into the arrhythmia group with 90 cases(the ventricular tachycardia group with 65 cases,the ventricular premature group with 25 cases)and the non arrhythmia group with 30 cases.According to echocardiography,they were divided into the reconstructed group with 42 cases and the non reconstruction group with 78 cases.According to the clinical outcomes of the different points they were divided into the cardiovascular event group with 15 cases and the non cardiovascular event group with105 cases.We compared Tp-Te and Tp-Te dispersion between the groups.Results:The Tp-Te and Tp-Te dispersion were statistically significant between the groups(P<0.05).Conclusion:The Tp-Te interval has a certain predictive effect on the occurrence and prognosis of arrhythmia after myocardial infarction.
