Developing the Effective Method of Spectral Harmonic Energy Ratio to Analyze the Arterial Pulse Spectrum
Figure 2
(a) The arterial pressure wave pumped by left ventricle flows into both organs and hands. Thus, the blood circulation forms a wave system. In the arterial pulse spectrum of a normal subject, the harmonic peaks decrease progressively. Hence, SHER is relatively low. (b) For a subject with heart disorder, the arterial pressure wave flowing into the organs might be influenced and the harmonic peaks decrease abruptly in the fourth, fifth and sixth harmonics. Thus, there is less energy in the above harmonic frequencies for the patient subject and SHER is relatively high.
