7 years ago i was dx with benign palpitations (not sure if pvc or pac). noticed at rest. every once in a while i will feel them a during exercise.

Palpations : Palpitations could be benign, but you must get evaluated to make sure you do not have an underlying rhythm such as Wolff-Parkinson-White syndrome or other arrhythmias you should see your doctor soon thank you

Harmless in a youngm: I would not be too concerned . They are considered benign in a otherwise healthy young man under 40 years of age. You can ignore them.
