Assessment Of Parasympathetic Autonomic Functions In Stage 1 Essential Hypertension By Deep Breathing Test.

Abstract :
Essential hypertension is having more incidence of resting tachycardia and arrhythmias. Resting heart rate is the index of vagal tone. Autonomic nerves supplying the heart may also be affected in essential hypertension causing cardiac autonomic neuropathy. When the parasympathetic system is abnormal, deep eathing induced changes in heart rate decrease i.e. heart rate variability (HRV) decreases. Parasympathetic autonomic functions are less studied in stage 1 essential hypertension. So the present study was aimed to measure E:I ratio during deep eathing in stage 1 essential hypertensive subjects. Study designed as analytical, cross–sectional, comparative study in the Department of Physiology B J medical college and hospital, Pune. 50 newly diagnosed essential hypertensive male subjects in the age group of 35 –50 years having stage 1 hypertension according to JNC 7 criteria were selected in study group. Healthy age and gender matched, 50 normotensive subjects were included in control group. After informed consent, E:I ratio was measured during deep eathing in the study and control group. Comparisons were performed using ‘z–test’ in the two groups. During deep eathing test E:I ratio was significantly decreased in stage 1 essential hypertensive subjects as compared to normotensive subjects. (p<0.05) Conclusion: The parasympathetic autonomic activity is decreased in stage 1essential hypertensive subjects as compared to normotensive subjects.
