Abstract
The present application provides an electrocardiogram signal quality assessment method, an electronic device and a chip system, and relates to the technical field of signal assessment. In the method, peak variability characteristics and peak quantity variability characteristics of multiple electrocardiogram signal samples are statistically analyzed, and the peak variability characteristics of the multiple electrocardiogram signal samples are used as an abnormal demarcation point, and the peak quantity variability characteristics of the multiple electrocardiogram signal samples are used as another abnormal demarcation point. According to the relationship between the peak variability characteristics and the peak quantity variability characteristics of the electrocardiogram signal to be assessed and the two abnormal demarcation points, it is determined whether the electrocardiogram signal to be assessed is a normal signal, an abnormal signal or a noise signal, and the method can accurately detect a normal electrocardiogram signal.
