Abstract
Background: Heart rate variability (HRV) means the beat-to-beat variations of cardiac rhythm which is influenced by the interplay of sympathetic and parasympathetic nerves. At present, cardiovascular morbidity and mortality have become a matter of great concern in the young population. Such complications may arise from cardiac dysautonomia. HRV analysis may be considered an efficient tool to detect this derangement as early as possible. Moreover, normative data on HRV should be established among the young population of India considering other demographic parameters such as gender, height, weight, and BMI.

Aim and Objective: Our study intends to establish normative data for short-term HRV parameters among medical students of a tertiary care hospital in West Bengal.

Materials and Methods: After obtaining approval from the Institutional Ethics Committee, 250 apparently healthy medical students were assessed and HRV parameters such as mean RR, mean HR, SDNN, NN50, pNN50, root mean square of successive differences (RMSSD), high frequency (HF), low frequency (LF), and LF/HF ratio were recorded.

Results: In time domain parameters, values were significantly higher in males for mean HR and significantly higher in females for mean RR, NN50, and pNN50. In frequency domain parameters, significantly higher values were found for LF and LF/HF ratio in males and HF in females.

Conclusion: We have established gender-based normative values of HRV parameters in the young population.

Key words: Heart Rate Variability; Normative Values; Medical Students
