This article assesses few electrocardiographic parameters in young adults (students) caused by smoking. The electrocardiogram of young smokers (with a history of at least six months of smoking) and young non-smokers were recorded using 12 leads, three channel ECG machine and the data thus obtained were analyzed statistically. It was found that there is extremely statistically significant difference in the timings of P-R interval and T-P interval when young smokers were compared with young non-smokers.
