Abstract

Background: Heart rate variability (HRV) has been considered as an indicator of autonomic nerve function status.

Objective:To find out the reference values of heart rate variability by time domain measures of HRV inadult Bangladeshi population of both sexes.

Methods:This cross-sectional, analytical study was conducted between July 2012 and June 2013. A total of 180 subjects were selected through the Department of Physiology, Dhaka Medical College Dhaka, Bangladesh, with the age ranging from 18 to 60 years. All the study subjects were divided into 3 different groups: group A (18-30 years), group B (31-45 years) and group C (46-60 years). Each group had 60 subjects: 30 males and 30 females. The experimentation of HRV parameters and recording of data were done using RMS Polyrite D (version 2.4) in Autonomic Nerve Function Test Laboratory of the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Mean systolic and diastolic blood pressure, heart rate along with R-R interval between successive QRS complexes, standard deviation of NN interval (SDNN), RMSSD (square root of mean squared differences between adjacent NN intervals) were observed and analyzed.

Results: Systolic and diastolic blood pressure and RMSSD were significantly higher in males than that of females in all three groups (P<0.001). However, no differences were observed in mean heart rate, R-R interval, and SDNN between males and females in any group.

Conclusion: Our data suggest that males have higher cardiac sympathetic activities, while females show higher cardiac parasympathetic activities in different age groups in terms of heart rate and blood pressure regulation. The difference of blood pressure is statistically significant; however, the difference of mean heart rate is not statistically significant.
