摘要
对41例急性心肌梗塞（AMI）患者行静脉溶栓治疗，分别测定其溶栓治疗前后QT离散度（QTd），探讨QTd在判断急性心肌梗塞溶栓治疗疗效的临床应用价值。结果：溶栓成功血管再通组25例溶栓前QTd为78．10±21．62ms，溶栓后QTd为41．20±18．23ms，两者比较差异非常显著（P＜0．01）；溶栓失败血管未通组16例溶栓前QTd为79．10±22．31ms，溶栓后QTd为74．20±21．56ms，两者比较差异无显著性（P＞0．05）。作者认为：AMI溶栓后QTd的变化可作为临床判定溶栓疗效的一项无创性指标。
Intravenous thrombolytic treatment was performedin 41 patients with acute myocardial infarction.The QT dispersion (QTd) on ECG was measured beforeand after thrombolytic therapy. The resultsshowed that infarct - related arteries were reopened in25 patients in whom QTd was dereased from 78. 10±21. 62ms to 41. 20±18. 23ms (P<0.01)and were mostreopened in 16 patients in whom QTd was 79. 10±22. 31ms and 74. 20± 21. 56ms (P> 0. 05 )respectively.It is considered that QTd may be used as a noninvasiveindicator to judge thrombolytic effect.
