Cardiovascular Parasympathetic Functions in Different Phases of Menstrual Cycle: A Prospective Observational Study

Ashwini N Nilekar, Kiran D Thorat, and Mangala Vatve.

Many studies suggest that all types of hormonal changes and a regular fluctuation in numerous functions affecting all body systems in women especially during menstrual phases including physical, psychological or behavioral is the result of disturbed autonomic nervous system (ANS) .In a present study the cardiovascular parasympathetic functions were assessed during various phases of menstrual cycle in 50 healthy, volunteers with no irregular menses, menorrhagia and oligo-menorrhoea. Parasympathetic functions were evaluated by Heart rate response, E: I Ratio and Valsalva Ratio tests in pre and post menstrual phases with statistically insignificant results (p>0.05), on comparison between the two phases. The study concludes that there were no statistical significant responses to any of the parasympathetic test on comparison between premenstrual phase and post menstrual phase of menstrual cycle, reflecting no change in the parasympathetic activity during the different phases of menstrual cycle.
