It sounds like Anxiety but if your scared about it you can reassure yourself by going to the Drs and getting them to take your blood pressure and listen to your heart. 

Best of luck and don't be worried.

Is this the first time you have felt like this? Have you had any tests run to rule out heart issues? Have you been diagnosed with anxiety?
