Hi welcome to HCM. Smoking contains nicotine and when released in the blood, it causes narrowing of blood vessels. This puts pressure on the heart which beats faster to try and pump blood into these narrowed vessels. This leads to a rapid pulse that lasts as long as the nicotine effect remains. You also have a raised cholesterol that adds to the problem. You say you have been smoking since 9 years and have been experiencing this problem only since two years. This could be because your arteries have become narrower now and the nicotine effect on them is more pronounced. Regards
