Tobacco consumption is the single most cause of the preventable deaths globally. Tobacco is consumed in the form of cigarettes. It contains nicotine which causes physical and psychological dependencies. Cigarette smoking increases the blood coagulability. Nicotine facilitates conduction block, re-entry and it increases the vulnerability to ventricular fibrillation. Hence, Nicotine and other components of cigarette can produce profound changes in the heart, which can be assessed by doing an ECG, which is the, cheapest and the most reliable method for assessing cardiovascular abnormalities.
