Iron deficiency anemia is considered as one of the major public health problem in Bangladesh. Cardiac autonomic nerve dysfunction may present in iron deficiency anemia which increases the risk and further complications of this disease. Assessment of heart rate variability (HRV) is a non-invasive technique to evaluate cardiac autonomic nerve function status. To assess the cardiac autonomic nerve function status by heart rate variability analysis, 100 female subjects with iron deficiency anemia aged 20-45 years were included in the study group. For comparison, age and sex matched 100 apparently healthy female were selected as control. The HRV parameters were recorded by a 4 active channels, Polyrite-D. Mean resting pulse rate, LF power, LF norm and LF/HF were significantly (p <0.0001) higher and total power, HF power, HF norm were significantly (p <0.0001) lower in subjects with iron deficiency anemia in comparison to those of control group. This study concludes that cardiac parasympathetic activity was reduced in female with iron deficiency anemia.Bangladesh Med J. 2014 Sep; 43 (3): 125-129

Background: Lower heart rate variability (HRV) in sedentary people is associated with higher risk of coronary heart diseases. Deep Relaxation Technique (DRT) generate higher HRV which reduces the risk of coronary heart disease. Objective: To assess HRV after practicing DRT to find out it’s effect on cardiac autonomic nerve function in sedentary subjects. Methods: This study with intervention by DRT was carried out in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University from July 2012 to June 2013 on 30 apparently healthy sedentary females aged 25-35 years practicing DRT for 3 months. 30 apparently healthy sedentary females who had no experience of relaxation technique constituted control. All subjects were sedentary housewives. The study subjects were participants in a private yoga center in Dhaka. HRV was assessed by RMS polynte D and frequency domain parameters were analysed. Statistical analysis was done by Independent Sample t-test. Results: Total power (p<0.001), HF power (p<0.01), HF norm (p<0.05) were significantly higher and LF power (p<0.001), LF norm (p<0.05), LF/HF (p<0.01) were significantly lower in the relaxation group than those of non relaxation group. Conclusion: Cardiac autonomic nerve function was improved by practice of DRT with parasympathetic dominance in sedentary females.

Objective. To explore the autonomic nerve rhythm and the correlation between palpitations below the heart (PBTH) and autonomic nerve function in patients with PBTH based on heart rate variability (HRV). Methods. The outpatients or ward patients of Wenzhou Hospital of Traditional Chinese Medicine were collected and divided into two groups: the PBTH group and the normal group. The HRV of each group was detected. Single-factor statistical methods, Spearman correlation analysis, and logistic regression were used to describe and analyze the rhythm and characteristics of autonomic nerves in patients with PBTH and the correlation between PBTH and autonomic nerve function. Results. (1) In the comparison of HRV in different time periods in the same group, the SDNN, RMSSD, pNN50, TP, and HF in the PBTH group at night were significantly higher than those in the daytime ( P < 0.01 ), while the LF/HF ratio was significantly lower than that in the daytime ( P < 0.01 ). (2) In the comparison of HRV between the two groups in the same time period, the RMSSD and pNN50 of the PBTH group during the daytime period were significantly higher than those of the normal control group ( P < 0.05 ), and the LF/HF was significantly lower than that of the normal group ( P < 0.05 ). (3) In the Spearman correlation analysis, PBTH was significantly correlated with RMSSD, pNN50, and LF/HF ratio in the daytime period, with correlation coefficients of 0.424, 0.462, and −0.524, respectively ( P < 0.05 ). (4) Logistic regression analysis showed that the decrease of LF/HF ratio during the daytime period was an independent risk factor for PBTH in TCM (OR = 0.474, 95% CI: 0.230–0.977, P < 0.05 ). Conclusions. The changes in parasympathetic nerve function in patients with PBTH have a circadian rhythm, which is characterized by increased activity during the nighttime. At the same time, the autonomic nerve activity of people with PBTH during the daytime is unbalanced, and the decrease of LF/HF ratio during the day is an independent high risk factor for PBTH.

Background: Nonlinear measure of heart rate variability (HRV) is an emerging tool to detect changes in cardiac autonomic nerve function (CANF) in transfusion dependent thalassemic (TDT) patients. Slow breathing exercise (SBE) can significantly improve HRV in health and various diseases. Objective: To observe the effect of slow breathing exercise (SBE) on non linear measures of HRV in TDT patients. Methods: This prospective interventional study was done in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka in 2018 on 60 male TDT patients aged 15-30 years. Thirty patients received conventional treatment and 30 patients performed slow breathing exercise along with the conventional treatment for 3 months. Age and sex matched 30 healthy control were enrolled. All subjects were followed up at baseline and after 3 months. Non linear (Poincare) HRV parameters were recorded by Power Lab 8/35 AD Instrument, Australia. For statistical analysis paired sample ‘ t’ test and independent sample ‘t’ test were used. Result: SD1, SD2 and SD1/SD2 were found significantly lower in TDT patients compared to healthy control at baseline. After 3 months of slow breathing exercise, significant increment of these parameters occurred with trend of improvement in cardiac autonomic nerve function in this group of patients. Conclusion: Slow breathing exercise may improve cardiac autonomic nerve function and sympathovagal balance in transfusion dependent thalassemic patients.

Background: Heart rate variability has been considered as an indicator of autonomic nerve function status. Few works have been done to assess the heart rate variability in normal healthy subjects in different countries. Objectives: To assess the cardiac autonomic nerve function status in healthy Bangladeshi population of different age groups by analyzing time domain measures of Heart Rate Variability. Methods: This cross sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from the period of July 2012 to June 2013. For this purpose, a total number of 180 healthy subjects were selected with the age ranging from 15-60 years of both sexes. All the study subjects were divided into 3 different groups according to age (Control 15-30 years; middle age 31-45 years; older age 46-60 years). Each group included 60 subjects of which 30 were male and 30 were female. The subjects were selected from different areas of Dhaka city by personal contacts. HRV parameters were recorded by a 4 active channels, RMS Polyrite-D-2 machine For statistical analysis, one way ANOVA, unpaired Student’s ‘t’-test and Pearson’s correlation coefficient test were performed. as applicable. Results: Systolic blood pressure (SBP), diastolic blood pressure (DBP) were significantly (p<0.001) higher in older group in comparison to control & middle age group. Again RR interval and RMSSD (p<0.001), were significantly lower in older age group (p<0.05) compared to control & also to middle age group. But HR was found significantly higher (p<0.05)in both middle and older subjects than control and also in older (p<0.05) compared to middle age. Correlation analysis showed moderate negative correlation of mean R-R with age in middle age whereas significant negative correlation for RMSSD both in middle and older age subjects. Conclusion: In this study, markedly decreased cardiac parasympathetic function were found with aging process.
