Assessment Of Effect Of Stress On Heart Rate Variability In Obese Subjects
Naveen Bhartia Porwal

Background:Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. The present study was conducted to assess effect of stress on heart rate variability in obese subjects. Materials & Methods: The present study was conducted on subjects (25 obese, 25 non- obese) of both genders. In all subjects, a baseline blood pressure was recorded using mercury sphygmomanometer. The baseline ECG was recorded for 5 minutes in both groups. The frequency domain of HRV analysis such as LFnu, HFnu and LF/HF ratio recordings was carried out. The mental stress test was applied as a mental stressor.  Results: SBP in group I was 112.6 mm Hg and in group II was 134.8 mm Hg, DBP in group I was 68.4 mm Hg and in group II was 76.6 mm Hg. The difference was significant (P< 0.05).LFnuin group I at rest was 31.5 and during mental stress was 36.7, HFnu in group I at rest was 46.4 and during mental stress was 49 and LF/HF ratio in group I at rest was 0.8 and during mental stress was 0.9. The difference was significant (P< 0.05). LFnuin group I at rest was 47.5 and during mental stress was 39.2, HFnu in group I at rest was 38.4 and during mental stress was 32.4 and LF/HF ratio in group I at rest was 1.3 and during mental stress was 1.2. The difference was significant (P< 0.05). Conclusion: Author found reduced autonomic neuronal activity to mental stress in obese subjects as compared to non- obese.

Key words: Autonomic neuronal activity, Obese, Stress
