心脑电图机是医院普遍使用的诊断检查设备。但在使用诊断及检定过程中,心脑电图机的交流干扰是最常见的也是最棘手的问题。干扰现象的产生直接影响心脑电图机波形图的准确性,使记录器所描述的图形幅值的波形产生突变,从而直接影响到医生的诊断。1.漏电流干扰。心脑电图诊断室内 EEG machine is a commonly used diagnostic test equipment in hospitals. However, in the use of diagnostic and verification process, the exchange of heart and brain EEG interference is the most common and most difficult problem. Interference phenomenon directly affects the accuracy of ECG waveform, the waveform of the waveform described by the recorder mutation, which directly affects the doctor’s diagnosis. 1. Leakage current interference. EEG diagnosis indoors
