| 摘 要： | 分析了运动心电信号心率变化对其各特征波形的持续时间的影响程度，其中受影响最大的是ＴＰ间期，其次是ＱＴ间期，Ｐ波和ＱＲＳ波群的宽度基本不变，并根据ＱＴ间期的变化特点给出了运动心电关键检测参数ＳＴ段值的自适应调整Ｊ点后取值位置，对于准确地识别运动心电信号的各特征波和判定运动试验的结果具有重要意义。

| Abstract: | This paper analyzes the characteristic wave intervals of exercise ECG influenced by heart rate changing under exercise test. The most influenced parameter is TP interval, the next is QT interval, and the width of P wave and QRS waves are nearly unchanging. According to the changing characteristic of these waves width mentioned above, we suggest an adaptive adjusting method for ST segment measuring position after the J point, which is of significance to recognizing the characteristic waves and determining the result of exercise test for myocardial ischemia. |
