Pulse Waveform Analysis Research Papers (original) (raw)

Background and Aim: In this study, radial artery pulse wave,
generated by a piezoelectric transducer, was analyzed for gender, age and Mizäj
(constitution) related variations in pulse wave parameters. The aim was to generate
a normal radial pulse wave profile for healthy subjects and to verify the claim
of Unani Medicine that pulse characteristics vary as per gender, age and Mizäj.
Experimental Procedure: Pulse wave parameters were measured in 133 women
and 127 men aged between 18 to 39 years. Pulse wave parameters observed
were Time to systolic peak (TP1), Amplitude of systolic peak (AP1), Interwave
time (IWT), Total pulse time (TPT) and Intra wave time (ZS).
Results and Conclusion: In all pulse wave parameters, a significant difference was
observed between males and females, with higher means in males as compared to
females except for AP1. In different age groups, a significant variance (p<0.05)
was found in TP1, TPT and ZS but not in AP1 and IWT. No significant variations
were seen in pulse parameters in different constitutions. The results support the
postulation of Unani Medicine that the characteristics of pulse vary according to
age and sex. The findings, however, do not support the assumption on genderbased
differences in the relative pulse strength assumed to be higher in males.
Similarly, the claim of Unani Medicine that pulse characteristics vary with Mizäj
was also not affirmed.
