Abstract
A pulse wave information display apparatus according to the present invention includes a storage portion for storing pulse wave data and a display portion. The pulse wave information display apparatus specifies a first characteristic point corresponding to a global maximum of an early systolic component in a waveform of one beat which has been extracted from the pulse wave data, and normalizes the waveform of one beat based on an amplitude value at the specified first characteristic point. Accordingly, a normalized waveform of one beat is displayed on the display portion.
