| 摘 要： | 目的:探讨临终患者伴发QT间期缩短的心电图特征和临床意义。方法:常规测量10例临终患者的QT间期实测值(QT),通过QT间期换算公式计算QT间期预测值(QTp)、校正后QT间期值(QTc)以及QT/QTp比值。结果:10例临终患者心电图除出现各型传导阻滞、心室停搏等心电异常外,均伴随QT间期缩短(QTc<0.32～0.34s、QT/QTp<0.88)。结论:继发性QT间期缩短可能是出现于临终患者的一种罕见心电图表现,在一定程度上反映了心脏电活动衰竭,其预后不良,应引起临床高度重视。

| Abstract: | Objective:To explore electrocardiogram(ECG) features and clinical significance of short QT interval in dying patients. Method:QT intervals of 10 dying patients were measured.Predicted QT intervals(QTp),corrected QT intervals(QTc),and the ratio of QT and QTp(QT/QTp) were calculated by QT interval conversion formula. Result:Except different kinds of heart block and ventricular standstill,all patients had short QT intervals(QTc<0.32-0.34 s,QT/QTp<0.88). Conclusion:Secondary short QT interval may be likely an rare ECG phenomenon in dying patients,and reflect electrical activity failure of heart. |
