Heart rate variability changes during stroop color and word test among genders.

Stress is the reaction of the body to a change that requires physical, mental or emotional adjustments. Individual differences in stress reactivity are a potentially important risk factor for gender-specific health problems in men and women. The Autonomic regulation of the cardiovascular system is most commonly affected by stress and is assessed by means of short term heart rate variability (HRV).

Poincare plot of heart rate variability: an approach towards explaining the cardiovascular autonomic function in obesity.

Obesity has been shown to affect cardiovascular function. Heart rate variability (HRV) has been an accepted method of measuring cardiovascular autonomic function. The aim of the study is to evaluate the impact of obesity on HRV using Poincaré plot (POP) analysis.

Measurement of the effect of Isha Yoga on cardiac autonomic nervous system using short-term heart rate variability.

Background: Beneficial effects of Yoga have been postulated to be due to modulation of the autonomic nervous system.

Objective: To assess the effect of Isha Yoga practices on cardiovascular autonomic nervous system through short-term heart rate variability (HRV).

Design Of The Study: Short-term HRV of long-term regular healthy 14 (12 males and 2 females) Isha Yoga practitioners was compared with that of age- and gender-matched 14 (12 males and 2 females) non-Yoga practitioners.

Heart rate variability in normotensive subjects with family history of hypertension.

Hypertension (HT) is a major silent disease affecting young people because of their hereditary and modern lifestyles. Target organ damages occur before overt hypertension is diagnosed. Many offspring of HT parents show early changes in their cardiovascular autonomic functions.
