回顾性单盲法分析99例急性心肌梗塞（AMI）发病24h内首次心电图未校正的QT离散度（QTd）、心率校正QT离散度（QIcd）和改良心率校正QT离散度（QTLcd），以各种离散度≥60ms为标准对预测发病1周内发生室性心作失常的敏感度分别为74.1％、81．5％和74.1％，特异度分别为52．8％、14．4％和63．9％，在敏感度无显著差异的情况下，QTLcd的特异度明显高于QTcd（P＜0.05）。认为临床选用QTLcd≥60ms作为预示AMI早期室性心律失常发生的方法更具价值。
The uncorrected QTd, QIcd and QTLd of the first electrocardiogram were analyzed retrospectively by single-blind method in 99 cases of acute myocardial infarction (AMI) The sensitivity of species dispersion ≥60ms was 74.1%, 81.5% and 74.1% respectively, and the specificity was 52.8%, 14.4% and 63% respectively .9%, the specificity of QTLcd was significantly higher than that of QTcd (P <0.05) in the case of no significant difference in sensitivity. That the clinical use of QTLcd ≥ 60ms as a means of early AMI ventricular arrhythmia occurs more valuable.
