Electromagnetic interference (EMI) can affect various medical devices. Herein, we report the case of EMI from wireless local area network (WLAN) on an electrocardiogram (ECG) monitoring system. A patient who had a prior myocardial infarction participated in the cardiac rehabilitation program in the sports medicine center of our hospital under the wireless ECG monitoring system. After WLAN was installed, wireless ECG monitoring system failed to show a proper ECG signal. ECG signal was distorted when WLAN was turned on, but it was normalized after turning off the WLAN.
电磁干扰（EMI）会影响各种医疗设备。在此，我们报告一个无线局域网络（WLAN）对心电图（ECG）监测系统产生 EMI 的案例。一名患有心肌梗死的患者在我院运动医学中心参加心脏康复计划，采用无线心电图监测系统。WLAN 安装后，无线心电图监测系统无法显示正常的 ECG 信号。当 WLAN 打开时，ECG 信号会发生扭曲，但关闭 WLAN 后又会恢复正常。
