VARIABILITY IN PERIPHERAL BLOOD FLOW AND MORPHOLOGY INDEX IN CONTROLS AND HYPERTENSIVE SUBJECTS

Manasi Sawant, G. D. Jindal, Sandhya Agarwal, Alaka K. Deshpande

Abstract


Peripheral pulse has been recorded in controls and hypertensive subjects with the help of peripheral pulse analyzer for analyzing peripheral blood
flow and morphological index variability as an alternative to blood pressure variability. Data in controls and patients has been age (less than and
above 30 years of age) and gender (male and female) stratified. One way analysis of variance has shown significant difference among all the 8
subgroups in 13 out of 16 variability parameters at 5% level of significance. Tukey's HSD test at the same significance level has shown gender wise
difference in 2 out of 64 comparisons, age wise difference in 7 out of 64 comparisons. Hypertension has shown significant change in 2 and 3
parameters in young male and female subjects respectively; with no significant change in higher age group. Significant changes observed in very
low frequency and high frequency parameters are similar to those observed in blood pressure variability.
