title: Assessment of Cardiovascular Autonomic Functions and Baroreceptor Reactivity in Women with Premenstrual Syndrome.
abstract: OBJECTIVE
  The study was conducted to assess the autonomic status of women with mild PMS using short-term heart rate variability (HRV) analysis and conventional autonomic function tests (CAFT).
  
  
  METHODS
  Sixty females in the age group 17-25 years with mild premenstrual syndrome were identified using a self-report questionnaire, the shortened premenstrual assessment form. HRV and CAFTs were recorded 1- 5 days prior and 8-10 days after menstruation.
  
  
  RESULTS
  The subjects showed a significant increase in HR and SBP in luteal phase. In HRV, an increase in mean HR and LF-HF ratio were seen in the luteal phase whereas an increase in the NN50, RMSSD and pNN50, HF, HF(nu) and TP were seen in the follicular phase. In CAFT, no change in HRB, 30:15 and El I ratios but increase in ?DBP(ihg) in the luteal phase was seen.
  
  
  CONCLUSIONS
  The increase in HR and SBP in the luteal phase could be because increased water and salt retention due to the ovarian steroids. A decrease in HRV, increase in ?DBPihg with no change in 30:15 ratio in the luteal phase could be attributed to delayed withdrawal of ovarian hormones in the luteal phase.
