I feel pounding in my heart, can I have something serious?

Sometimes, all of a sudden, I feel like it's a throbbing in my heart, I do not know for sure, but I think it's like he's going to jump out of my chest and sometimes I can not take a deep breath. I have no history of heart problems in the family. Can I have something serious? Thank you!
Expert answer:

Palpitations always lead us to think of a heart problem, but in a young adult with no risk factors for heart disease, anxiety, stress and emotional problems in general are the most common causes for palpitations.
