摘　　要：为评价冠心病者及高心病的Q -T离散度的临床意义 ,观察了 97例冠心病、高心病患者的Q -T离散度 ,并与 96例正常组对比。结果表明 ,冠心病、高心病患者的QTd、Q -Tcd、J-Td、J -Tcd均比正常组延长 ,有显著差异 ,P <0 0 1。冠心组高心组发生心律失常占 4 1%。认为Q -Td、J -Jd增大是预测心律失常有意义的指标。To evaluate the Q-T dispersion of coronary heart disease and Hypertensive Cardio pathy,97 cases with coronary heart disease and Hypertensive Caredio pathy were observed on Q-T dispersion and compared with that of 96 nomal controls.The results show that there are distinctive difference in QTd,Q-Tcd,J-Td,J-Tcd( P <0 01).The rate of arrhythmia cordis of disease group is 41%.It indicates that the values of Q-Td and J-Td are useful index for diagnosing heart disease.
