The aim of present study was to compare the heart rate variability parameters in healthy adult males and females. It is known that many factors influence the heart rate variability, one of which is gender. Gender difference in heart rate variability parameters is due to different activity of autonomic nervous system in both genders. Fifty healthy young males with age 18-25 years and BMI 18-25 kg/m2 taken part in this study. HRV parameters of subjects were recorded after making them comfortable by resting in supine posture for 15 minutes. The recording was done in 5 minutes in the supine position by Recorder and Medicare System (P) Ltd. (RMS) Polyrite D. Intergroup comparison between male and female was done by using unpaired‘t’ test. HRV parameters like mean R-R interval, mean values of low frequency in normalized unit (LF nu), mean values Total Power (TP) and mean values of LF/HF ratio were high in males than females but mean high frequency in normalized unit ( HF nu) were high in females than males. Males have sympathetic dominance whereas females have parasympathetic dominance.
