Key result
Cigarette smoking in healthy adult males significantly increased the LF/HF ratio (3.10 vs 2.44, p<0.01), indicating increased sympathetic and decreased parasympathetic activity.

This cross-sectional study evaluates the effect of cigarette smoking on heart rate variability as a measure of autonomic nervous system regulation in healthy adults.
Smoking may alter HRV in healthy adults; leaves open causal effects on autonomic function and needs prospective confirmation.
Background: Smoking has acute deleterious effects on the blood pressure and sympathetic tone, and it reduces the myocardial oxygen supply. HRV is recognized as an effective and noninvasive tool for evaluating autonomic nervous system regulations of the heart. AIM: The aim of our study was to observe the effect of cigarette smoking on heart rate variability in healthy adult smokers in the age group of 20 -60 years. Material And Method: A cross-sectional (observational) study was conducted on 60 healthy adult smokers and 60 healthy non-smokers in the age group of 20-60 years. Heart Rate Variability (HRV) was recorded by Physio Pac (PC-2004). The data consisted of anthropometric parameters analysis, Time Domain Analysis and Frequency Domain Analysis in smokers and controls. Data collected was analysed statistically.

Kaur et al. (2017) conducted a cross-sectional in Healthy adult smokers and non-smokers (n=120). Cigarette smoking vs. Non-smokers was evaluated on LF/HF ratio (p=<0.01). Cigarette smoking in healthy adult males significantly increased the LF/HF ratio (3.10 vs 2.44, p<0.01), indicating increased sympathetic and decreased parasympathetic activity.
