Radial pulse analysis at deep pressure in abnormal health conditions

Radial pulse analysis is popular as complementary approach for health diagnosis in India and China. Three pulse pressure signals on the two hands carry rich information about health status. Pressure applied while observing the pulse signal plays an important role in the analysis of the body conditions based on dynamic nature of the pulse signal. Deep pressure is the pressure applied on pulse point prior to complete obstruction of radial artery. Pulse morphologies for deep pressure in abnormal health conditions are studied for the group of subjects suffering from chronic gastritis, arthritis and prostate enlargement. Two abnormal pulse patterns have been identified relating to the characteristics of dicrotic notch at deep pressure and the dynamics of pulse segment in the late diastole phase of the pulse. These new abnormal pulse patterns are identified with their correlation to abnormal status. Time domain quantification parameters namely Dicrotic Notch Suppression Ratio (DNSR) and BAD Notch Ratio are defined to identify their presence.
