Abstract
Method and apparatus for analyzing the propagation of arterial pulse waves in a patient's circulatory system. The apparatus comprises R-wave detecting means for outputting an R-wave timing signal at the time of detection of the R-wave component contained in a detected electrocardiographic signal. A pulse wave peak detecting means is provided for outputting a peak timing signal at the time of the detection of a selected peak of the arterial pulse wave detected in the peripheral blood vessels of a patient's circulatory system. A pulse wave propagation time counter is provided for successively counting the time interval from the input of the R-wave timing signal to the input of the peak timing signal, and a pulse wave propagation time analyzer is provided for analyzing the distribution of pulse wave propagation times and other detected biophysiological parameters, from which an effective diagnosis of the condition of the patient's circulatory system can be made.
