巨大倒置T波对冠心病的诊断价值

Value of giant T wave inversion in diagnosis of coronary heart disease

目的:探讨静息心电图巨大倒置T波在冠心病诊断中的临床意义。方法:回顾性分析206例静息心电图巨大倒置T波患者的临床资料,对其临床特征、心电图、超声心动图、肌钙蛋白及冠状动脉造影结果进行统计分析。结果:静息心电图示一过性形态对称巨大倒置T波主要见于冠心病,特别是急性冠状动脉综合征(不稳定性心绞痛、急性心肌梗死)占71.7%;持续性巨大倒置T波亦主要见于各类器质性心脏病,心电图T波形态对称且无左室肥大者冠心病占85.7%。结论:持续性形态对称巨大倒置T波且无左室肥大或一过性形态对称巨大倒置T波对冠心病尤其是急性冠状动脉综合征有预测和临床诊断价值。

Objective：To explore the value of giant T wave inversion in diagnosis of coronary heart disease.Methods：Clinical data of 206 cases with giant T wave inversion were retrospectively analyzed,and clinical characters,electrocardiogram,echocardiography,troponin level and coronary angiography were analyzed.Results：Resting electrocardiogram showed transient symmetric giant T wave inversion mainly in patients with coronary heart diseases,in which acute coronary syndrome（unstable angina pectoris,acute myocardial infarction） accounted for 71.7%.Sustaining giant T wave inversion also appeared in electrocardiogram of organic heart disease,in which patients with symmetric T wave but no left ventricular hypertrophy accounted for 85.7%.Conclusions：Sustaining giant T wave inversion without left ventricular hypertrophy or transient symmetric giant T wave inversion is valuable in prevention and diagnosis of acute coronary syndrome.
