How to tell if my palpitations are serious or not?

Palpitations. They can be serious. But, most humans have palpitations. Many of us do not pay enough attention to know it though. Here is some good advice: if you have other symptoms with your palpitations such as shortness of breath, chest pain, numbness in your teeth or if the palpitations persist for more than a few seconds you may well go see your family doctor to discuss. If they seem severe call 911.
Get medically. Evaluated to determine the cause of your palpitations. The physician will advise if you if the reason is serious or not.
