Abstract
Background: Cigarette smoking is major risk factor for theSmoking is mediated by impaired autonomic nervous system (ANS) activity. development of atherosclerosis. Cigarette smoking alters baseline sympathetic and vagal modulation of the sinoatrial node (S-A Node) and peripheral sympathetic vascular control. Aims & Objective: To assess the effect of active smoking on ANS function as manifested by Heart rate variability or deep breathing test abnormalities. The present cross sectional study was carried out in the Department ofMethods And Materials: Physiology, Madhubani Medical College, Madhubani, Bihar during April 2021 to March 2022 and it was approved by the Institutional Ethical and Research Committee. Result: The difference was observed between the mean values of the Para sympathetic function tests in the smokers and the non – smokers (i.e. p<0.01). It was seen that the Resting Heart Rate had signi?cantly increased and that the Expiration: Inspiration Ratio, the 30:15 Ratio (Response to standing) and the Valsalva Ratio had signi?cantly decreased in the smokers as compared to those in the non – smokers. Conclusion: The cardiovascular autonomic function tests are reliable, non-invasive and easy to carry out. By doing some simple tests we can detect the early involvement of the autonomic nervous system before the clinical symptoms appears. The results of this study are suggestive of decreased sympathetic reactivity in smokers.
