摘　　要：心脑电图机(ECG-EEG)可客观完整地记录心脏或大脑活动时所产生在身体表面的电位差,为临床疾病诊断提供依据,而临床将并非由心脏或大脑活动而引发心脑电图上的改变称之为"伪差"(即干扰),心脑电图波形的质量直接影响医生对患者体质参数等的判断。为此,从机内和机外两方面分析干扰ECG-EEG使用的信号来源,并总结排除干扰的对策,对提高临床疾病诊断的准确率及促进ECG-EEG在临床中的应用有积极意义。Electrocardiogram-electroencephalogram(ECG-EEG)can objectively and completely record the potential difference that generated on the body surface by the heart or brain activity,and provide basis for the diagnosis of clinical diseases.And the changes that didn’t come from the heart or brain activity in ECG-EEG were called as“false difference”(Interference),and the quality of wave figuration of ECG-EEG could directly affect the judgment of doctors on the body mass parameters of patients.Therefore,the analysis of signal source that interfered the usage of ECG-EEG from two aspects included the intra and external of machine and the summary of the countermeasures that eliminated interference have positive significance in increasing the accuracy of the diagnosis of clinical disease and promoting the application of ECG-EEG in clinical work.
