摘　　要：抗运动伪迹是动态心电监测设备最重要的性能之一,当前缺乏能够规范化测试抗运动伪迹性能的手段。采用心电模拟仪和特制导电皮革构建模拟人体皮肤的装置,为贴附在上面的心电监测设备产生心电信号输入。采用机械臂和固定支架来搭建运动模拟系统,将导电皮革固定上去,对机械臂编程实现人体各种运动状态的模拟,让心电监测设备产生相应的运动伪迹。采用无线方式对读取采集到的心电信号进行观察、分析、对比,评价心电监测设备的抗运动伪迹性能。试验结果显示,为了给两组动态心电监测设备人为制造出微小差异,系统可以精准测试出在拉伸、扭转等可控运动条件下引入的干扰信号,并比较优劣。研究证明,该测试系统可为优化抗运动干扰的研究提供方便、准确的验证手段,可帮助持续提升心电产品抗运动伪迹性能。Anti-motion artifact is one of the most important properties of ambulatory ECG monitoring equipment.At present,there is a lack of standardized means to test the performance of anti-motion artifact.ECG simulator and special conductive leather are used to build the simulator,it is used to simulate human skin,to generate ECG signal input for the ECG monitoring equipment attached to it.The mechanical arm and fixed support are used to build a motion simulation system to fix the conductive leather.The mechanical arm is programmed to simulate various motion states of the human body,so that the ECG monitoring equipment can produce corresponding motion artifacts.The collected ECG signals are read wirelessly,observed,analyzed and compared,and the anti-motion artifact performance of ECG monitoring equipment is evaluated.The test results show that by artificially creating the small difference between the two groups of ambulatory ECG monitoring equipment,the system can accurately test the interference signals introduced under the conditions of controlled movement such as tension and torsion,and compare the advantages and disadvantages.The research shows that the test system can provide convenient and accurate verification means for the research of optimizing anti-motion interference.
