对177例AMI早期QT JTc变化结合临床进行了分析。结果表明,QTc延长组心律失常(56.1％),左心衰竭(56.1％),病死率(43.9％)均显著高于QTc正常组(分别为25.0％,20.2％,14.4％)(P<0.005)。QTc缩短组心律失常(50.0％)也显著高于QTc正常组(P<0.05)。JTc延长组心律失常(62.9％),左心衰竭(62.9％),病死率(37.1％)均显著高于JTc正常组(分别为22.2％,21.4％,17.0％(P<0.025％0.001)。JTc缩短组的并发症,病死率亦均显著高于JTc正常组(P<0.05—0.001)。表明,AMT早期QTc,JTc延长与缩短者并发症多,病死率高。QTcJTc变化对AMT并发症的发生及预后有预报价值。
177 patients with AMI early QT JTc changes combined with clinical analysis. The results showed that arrhythmia (56.1%), left heart failure (56.1%) and mortality (43.9%) in QTc prolonged group were significantly higher than those in QTc normal group (25.0%, 20.2%, 14.4% ). QTc shortening arrhythmia (50.0%) was also significantly higher than QTc normal group (P <0.05). Arrhythmia (62.9%), left ventricular failure (62.9%) and mortality (37.1%) in JTc prolonged group were significantly higher than those in JTc normal group (22.2%, 21.4%, 17.0%, P <0.025%, 0.001 respectively). JTc shortened group complications and case fatality were also significantly higher than the normal JTc group (P <0.05-0.001) .Therefore, early AMT QTc, JTc prolongation and shortening more complications and high mortality.QTcJTc changes in AMT complications The occurrence and prognosis of the forecast value.
