Abstract

Background: Smoking is a detriment to physical fitness even among relatively young, fit individuals with lower physical endurance than non-smokers. The present study was conducted to assess effect of exercise on electrocardiographic parameters amongst smokers and non- smokers.
Materials & Methods: 120 smokers and non- smokers of both genders were equally divided into two groups, i.e., Group I (smokers) and Group II (non-smokers). The baseline pulse and blood pressure were taken, whereas ECG parameters were recorded by using BIOPAC in both groups.
Results: Group I had 45 males and 15 females and group II had 48 males and 12 females. There was significant difference in P wave, QRS, QT interval, ST segment, SBP, DBP and pulse rate after exercise in both groups. The difference was significant (P< 0.05).
Conclusion: Smokers shows more variations in ECG and cardiovascular parameters after exercise than non- smokers and hence are more prone to cardiovascular diseases
