Abstract
When pulse waveform MH is detected by pulse wave detection sensor unit wavelet transformer performs wavelet transformation on pulse waveform MH and generates analyzed pulse wave data MKD. This analyzed pulse wave data MKD consists of a time region in which one heartbeat is divided into eighths, and the frequency region of 0-4 Hz which has been divided into eighths. Frequency corrector generates corrected pulse wave data MKD′ by performing frequency correction on analyzed pulse wave data MKD. Pulse type data generator compares corrected pulse wave data MKD′ over each frequency-time region, and generates pulse type data ZD indicating the type of pulse. Display displays the pulse type for pulse waveform MH based on pulse type data ZD.
