QT离散度(QTd)是指心电图各导联间QT间期变异的程度,反映了心室肌复极的非同步性,急性心肌梗死(AMI)后QTd明显增加,本文通过观察57例溶栓与未溶栓的QTd,以探讨溶栓对QTd的影响。
QT Dispersion (QTd) refers to the degree of QT interval variation between ECG leads, which reflects the nonsynchrony of ventricular repolarization. QTd is significantly increased after acute myocardial infarction (AMI) No thrombolytic QTd, to explore the impact of thrombolytic QTd.
