Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 8
Abstract
Background: In India, tobacco kills 8–10 lakh people each year and majority of these deaths occur in young age. An estimate says that an average of five-and-a-half minutes of life is lost for each cigarette smoked. A 12- lead electrocardiogram (ECG) is aroutine, inexpensive tool for assessment of cardiovascular disease in both clinical and research setting and ECG changes powerfully predicts future CVD events Hence the present study is carried out to demonstrate the effects of smoking on electrocardiogram and thereby creating awareness and the potential benefits of primordial prevention in such population. Materials and methods: This study was carried out in the department of Physiology, Sri Venkateswara medical college, Tirupati, Andhra Pradesh, India. Informed consent was obtained from all the participants. The study group comprised of 45 males with age range between 40 and 55years and 45 age matched males as controls. The smokers in this study were that smoking 11-20 cigarette/day for last 15 years. Questionnaires were administered to provide the details about their smoking habits. Results: In the present study of 90 subjects, 45 non - smokers and 45 smokers, who smoke 11 - 25 cigarettes per day for the past 15 years. In this case-control study, it was found that abnormalities in ECG parameters were more likely to be prevalent in smokers as compared to non-smokers. QTc-interval increased with increase in pack years of smoking. P-wave duration, PR-interval, Conclusion: This study clearly showed the importance of ECG evaluation in young healthy smokers. These ECG abnormalities indicate cardiovascular risk in term of cardiac arrhythmia, pulmonary arterial hypertension, heart blocks etc in such subjects.
