Background and Aim: The nicotine present in the cigarette smoke induces conduction block, acts as a cardiac A-type potassium channels blockers and increase the ventricular fibril formation which also changes the cardiac electric impulses usually assessed via electrocardiogram (ECG). The present study aims to evaluate and compare the ECG profile change in seemingly fit smokers and non-smokers. Materials and Methods: The present study was conducted in the Department of Medicine, for two years involved 148 patients evaluated for different parameters heart rate, the PR interval, QRS complex QTc (corrected QT interval) using a 12 lead ECG. P-value < 0> Results: All the patients were male and the mean age was comparable in non-smoking group (NS) vs smoking group (S) (29.26±5.90 vs. 30.42±6.19 years; p=0.244). Mean systolic (127.43 ± 7.29 (S) vs. 123.03 ± 6.96 (NS) mm Hg; p Conclusion: Smokers show abnormalities in the ECG profile that may eventually increase the risk of incidence of cardiovascular diseases.
