The invention is applicable to the field of
biological signal processing, and provides an electrocardiographic scatter point display method and device. The electrocardiographic scatter point display method comprises: respectively acquiring data characteristics and a
heartbeat type of each QRS
wave group in an electrocardiographic
signal; determining a layer corresponding to the
heartbeat type in an electrocardiographic scatter point diagram; calculating a position point of the QRS group in the layer according to the data characteristics, and generating an electrocardiographic scatter point corresponding to the QRS group at the position point; acquiring a
heart rate ratio of the position point, and calculating the color brightness based on the
heart rate ratio; and rendering a color to theelectrocardiographic scatter point of the position point according to the color brightness. The invention reflects the overall signs of different
heartbeat type electrocardiographic scatter points onthe basis of the degree of scatter point colors and different
layers, can avoid the problem that the electrocardiographic scatter point display mode is too single and the interaction performance is poor, can ensure that in the case of a large number of electrocardiographic scatter points, a user does not appear visually confusing, can enable the user to quickly identify the QRS
wave group of theabnormal
rhythm from the electrocardiographic scatter point diagram, thereby improving the diagnostic efficiency.
