Methods:QTd and QT corrective dispersion (QTcd) of 48 cases with AMI were measured in 6 h when the patients were attacked. The changes of QTd and QTcd were compared between effective group and ineffective group.

• 方法:对48例急性心肌梗死患者在发病6h内予以尿激酶溶栓治疗,比较AMI溶栓成功组与溶栓失败组治疗前后QT离散度(QTd)和QT离散度校正值(QTcd),比较各组溶栓前和溶栓治疗后7d内复杂室性心律失常(CVA)事件发生率。
