Abstract
A microcomputer performs a frequency analysis of pulse waves which are taken at regular time intervals from a patient through a pulse wave detection section. Then, if the amplitudes and phases of the spectra of the pulse waves fulfill some set conditions, either .alpha.-blocker or .beta.-blocker is given to the patient, and the patient's circulatory activity is maintained in a stable condition.
