Probable Causation of Abnormal Phenomenon of Electrocardiograph ADS Functionality
摘要
Abstract
Objective To research the probable causation of abnormal phenomemom of electrocardiograph ADS functionality.Methods The probable causation was analyzed from digital filter method, time constant, frequency superposition,and so forth. Reaults digital filter method and less time constant were probable causations of low frequency signal distortion, while frequency superposition was the probable causation of high frequency signal drifting. Conclusion Digital filter method,less time constant and frequency superposition are the probable causations of the abnormal phenomenon of electrocardiograph ADS functionality.[Chinese Medical Equipment Journal , 2011 ,32( 5 ) : 98-101]关键词
