回顾性单盲法分析 10 6例急性心肌梗塞 (AMI)患者入院后首次心电图 ,参照室性心律失常Lown和Woff分级分组 ,观察QT离散度 (QTd)与室性心律失常恶性程度的关系 ,探讨QTd对AMI患者预后的预测价值。结果显示 ,QTd在AMI患者各亚组间和AMI组与正常对照组间差异均具有高度显著性 (P均 <0 0 1) ,且AMI组QTd与所发的室性心律失常恶性程度呈正相关 (rs’ =0 .5 73)。认为QTd值检测 ,对AMI预后的预测具有一定的临床意义
Retrospective single-blind analysis of 106 patients with acute myocardial infarction (AMI) in patients with first electrocardiogram after admission, with reference to ventricular arrhythmias Lown and Woff grading group, observation QTd (QTd) and ventricular arrhythmia severity The prognostic value of QTd in AMI patients. The results showed that the QTd was highly significant among AMI patients and AMI patients (P <0.01), and the QTd of AMI patients was positively correlated with the severity of ventricular arrhythmias (rs’ = 0 .5 73). QTd value that the prognosis of the prognosis of AMI has some clinical significance
