摘要
目的 为探讨QT间期离散度的临床价值。方法 对 96例急性心肌梗塞 (AMI)患者体表心电图 1 2导联QT间期离散度 (QTd)进行了回顾性分析。结果 AMI2 4小时内QTd明显长于对照组(P <0 .0 1 ) ,AMI死亡组QTd明显长于生存组 (P <0 .0 0 1 ) ;AMI中死于室颤 ,室速者QTd也长于死于其它并发症 (P <0 .1 0 )。结论 QTd是一种简单 。
Objectie To probe into the clinical value of quiet dispersion degree(QTd). Methods The body surface twelve electocardiographic lead QTd of 96 cases with AMI were analzyed. Results The QTd of the death group with AMI was clearly longer than that of contrast group(P<0.001)and that of survival group(P<0.01)in24hours; The QTd of the deaths of patients with AMI from vibration and veolcityof ventriculus cordis was longer than that of the deaths with other complications. Conclusion QTd is a simple and cheap examing method to reflect the stress of ventriculus cordis.
