男性心电监护服装电极最佳位置的设计研究

Research and design for optimal position of electrocardio-electrodes in monitoring clothing for men

为了有效降低心血管病患者的死亡率,提高心电监护服装采集信号的准确性,减少由电极在服装中不适当的位置引起的运动伪迹对心电信号测量效果的影响,本文对3导联监测方法下男性心电监护服装电极的最佳位置进行了实验研究。实验在男性心电监护服装的3导联区域选择相应测试点,通过对各组位置点所采集到的心电信号质量进行比较,以及对心电图及功率谱图的分析,最终确定最佳位置点。结果发现在电极的最佳位置处,由电极不适当位置引起的运动伪迹得到明显改善。心电监护服装中电极的位置对于心电信号的日常采集至关重要,电极在最佳位置处,所采集的心电信号的稳定性得到明显提高。

In order to reduce the mortality rate of cardiovascular disease patients effectively, improve the electrocardiogram （ECG） accuracy of signal acquisition, and reduce the influence of motion artifacts caused by the electrodes in inappropriate location in the clothing for ECG measurement, we in this article present a research on the optimum place of ECG electrodes in male clothing using three-lead monitoring methods. In the 3-lead ECG monitoring clothing for men we selected test points. Comparing the ECG and power spectrum analysis of the acquired ECG signal quality of each group of points, we determined the best location of ECG electrodes in the male monitoring clothing. The electrode motion artifacts caused by improper location had been significantly improved when electrodes were put in the best position of the clothing for men. The position of electrodes is crucial for ECG monitoring clothing. The stability of the acquired ECG signal could be improved significantly when electrodes are put at optimal locations.
