自1990年Day等首先证实了心率校正QT离散度(QTcd)具有重要的临床价值,到目前为止QTcd的应用已涉及到心血管疾病的各个方面,包括特发性QT延长综合征、心肌肥厚、心力衰竭、缺血性心脏病、 心律失常、药物影响等。QTcd异常增大在急性心肌梗塞(AMI)患者中表现尤为突出,与恶性心律失常关系密切。本文分析AMI患者行尿激酶静脉溶栓治疗成功前后心电图,旨在探讨AMI静脉溶栓成功对QTcd的影响及临床意义。 1 对象 62例AMI患者,男51例,女11例,符合1979年
Since 1990, Day et al. First confirmed the important clinical value of QTcd (Heart Rate Correction QT Dispersion), and so far the application of QTcd has covered all aspects of cardiovascular disease including idiopathic QT prolongation syndrome, cardiac hypertrophy, Heart failure, ischemic heart disease, arrhythmia, drug effects and the like. QTcd abnormal increase in patients with acute myocardial infarction (AMI) performance is particularly prominent, and malignant arrhythmias are closely related. This article analyzes the AMI patients with urokinase intravenous thrombolysis before and after treatment of ECG, to explore the success of AMI intravenous thrombolytic QTcd impact and clinical significance. 1 object 62 cases of AMI patients, 51 males and 11 females, in line with 1979
