Journal Title: International Journal of Medical and Health Sciences - Year 2015, Vol 4, Issue 2
Abstract
Introduction: Cigarette smoking is one of the major risk factor for cardiovascular diseases and epidemiological studies have established a gradient of risk; the highest for containing smokers, intermediate for reformed smokers and the lowest for nonsmokers. Materials & Methodology: The present cross sectional study conducted in Department of physiology, D.Y.Patil Medical College, Kolhapur in male individuals above 18 years up to 70 years of age group selected from the general population. The aim of the study was to know electrocardiographic pattern in non-smokers, to study electrocardiographic changes in different group of smokers, to compare the electrocardiographic changes in non-smoker to smokers. After consent detailed history from subjects, electrocardiogram was recorded during resting state in supine position. The ECG results are evaluated for different parameters. Results: The smokers & heavy smokers showed decrease in P-R interval. There was decrease in QRS complex in smokers and heavy smokers. There was difference in R wave voltage in smokers compared to non-smokers. S-waves voltage in smokers and non-smokers showed difference. ST segment shows difference in smoker and heavy smoker group. Т-Р interval has decrease in heavy smokers to non-smokers which may alter the heart rate. There was highly significant difference showed in Twave abnormality in smoker & heavy smoker compared to non- smoker. Conclusion: Smokers and heavy smokers are prone for cardiovascular risk. Social climate conducive for non-smoking may be helpful to combat the epidemic of tobacco smoking.
