Background: Irritable bowel syndrome (IBS) may be associated with autonomic nerve dysfunction. However, moderate to vigorous physical exercise cause improvement of this nerve function. Objective: To observe the effect of moderate physical exercise on the autonomic nerve activity by analysis of HRV in patients with Irritable bowel syndrome. Methods: This prospective study was carried out in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka in 2013. For this purpose, 77 male patients aged 20-50 years with IBS were included in the study. They were subdivided into IBS-D (24 patients), IBS-C (26 patients) and IBS-A (27 patients) and were selected from the OPD, Gastroenterology, BSMMU. 28 apparently healthy male were studied as control. HRV parameters were recorded prior to onset of physical exercise and after completion of 3 months of brisk walking. For assessing autonomic nerve function, some time domain measures of HRV were recorded by Polyrite D. ANOVA, Independent sample t-test and paired t-tests were used for statistical analysis. Results: The pre-exercise values of mean R-R interval, Max/Min ratio, SDNN,RMSSD, NN50%, PNN50% were significantly(p<0.05) lower and mean heart rate was significantly (p<0.05) higher in all IBS patients compared to control. The post exercise data showed mean HR was significantly decreased in IBS-A and SDNN & RMSSD were significantly increased in IBS-C and IBS-A. Conclusion: This study concluded that parasympathetic activity decreased in patients with IBS, which was improved after regular moderate physical exercise of 3 months.

Background: Reduced heart rate variability (HRV) with cardiac autonomic nerve dysfunction has been found in Type 2 Diabetes Mellitus (T2DM) patients. Yoga based slow breathing exercise (SBE) improved this autonomic functions in healthy subjects. Objectives: To assess the effect of SBE on cardiac autonomic nerve function(CANF) by power spectral analysis of HRV in patients with T2DM. Methods: This prospective interventional study was carried on 30 male diagnosed T2DM patients aged 45-55 years with disease duration 5-10 years enrolled from Out Patient Department of Endocrinology, Bangabandhu Sheikh Mujib Medical University, Dhaka. They performed SBE for 30 minutes twice daily for 3 months. Thirty apparently healthy age, BMI matched male who did not undergo any type of exercise were included as control. To assess the cardiac autonomic nerve function, power spectral analysis of HRV of all patients were done before and after 3 months of SBE. HRV data were recorded by polyrite D (RMS India). For statistical analysis, independent sample and paired sample t-test were used. Results: The preintervention values of Low frequency (LF) normalized unit(nu) and Low frequency/High frequency( LF/HF) ratio were significantly (p<0.001) higher and the values of LF power, HF power, HF normalized unit (HF nu) were significantly (p<0.001) lower in all diabetic patients compared to control. The postintervention values of LF power, HF power, HF nu increased significantly (p<0.001) and the LF nu, LF/HF ratio decreased significantly (p<0.001)compared to their pre-intervention values in T2DM. There were no significant differences between the post intervention values of LF nu, HF nu and LF/HF ratio in T2DM and the control. Conclusion: Impaired cardiac autonomic nerve function was significantly improved by SBE in T2DM. J Bangladesh Soc Physiol. 2019, December; 14(2): 63-68

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
