They're different situations. the reason why your heart beats faster was already explained (not getting enough oxygen to vital organs) but Exercising only puts your heart rate up temporarily.
Smoking raises it and it stays at a high rate for longer periods. and your heart is struggling CONSTANTLY to get oxygen through your body, which stresses it out and puts you at risk for multiple problems

Your body needs more oxygen when you are exercising, so your heart beats faster to pump the blood quicker and get it delivering the oxygen quicker.
When you smoke, you aren't getting enough oxygen. You are breathing in useless crud instead. Your heart beats faster meaning there is even more demand for oxygen that isn't there.
So that’s the difference. When you exercise your heart speeds up to help you work and give your body what it needs, when you smoke, it speeds up because you are making it work too hard and not giving your body what it needs.

The difference is Smoking gives you Cancer. It has nothing to do wheter your heart is beating fast.
