QT离散度对急性心肌梗塞患者室性心律失常的预测价值

PREDICTION VALUE OF VENTRICULAR ARRHATHMIA OF PATIENTS WITH ACUTE MYOCARDIAL INFARCTION BY QT DISPERSION

为探讨QT离散度的临床意义，分析了50例急性心肌梗定（Acutemyocrfailinfarction，AMI）患者心电图的QT离散度。结果发现，AMI1周内患者的QT离散度显著大于陈旧性心肌梗塞患者和健康人；并发心律失常的AMI患者的QT离散度大于无心律失常的AMI患者．提示QT离散度对掌握AMI患者病情及预后有重要指导意义。

QT dispersion of 50 patients with acute myocardial infarction (AMI) was analyzed inorder to study its clinical significance. The resultsshowed that QT .dispersion of patients sufferingfrom AMI within I week was greater than that ofold AMI and normal subjects, and that QT dispersion of patients with arrbthha was greater than thatwithout arrhthnda. It suggests that QT disper,ioncan predict the patient's condition and prognOSis of
