Not usually: Palpitations in young people usually aren't dangerous -- but they can be annoying. Exercise and stress reduction can help. Some people get palpitations because of thyroid disease, and you might want to have your thyroid level checked. If you are having problems with lightheadedness, fainting, or shortness of breath, those are signs it might be something more serious.

Not necessarily : Sometimes palpitations are associated w bad heart rhythms, but also occur in healthy people. Not uncommon to occur in healthy young women. (personal experience). Can be scary. Sometimes worse in some positions than others (lying on one side vs the other). Caffeine & stress/anxiety can make them worse. Sometimes a med like atenolol can help but it can have side effects too. Ask your doc.
