Heart Palpitations. Anyone else?

This is a very broad topic. But I definitely want any and all input - nothing is irrelevant.
Does anyone have, not chronic but, consistent heart palpitations WITHOUT a heart condition or anxiety disorder??
I seem to get palpitations in the form of a slightly elevated heart rate (not rapid), pounding heartbeat, or both together. They're extremely uncomfortable.
I do not have anxiety, any heart rhythm or structural disorder, and I do not consume in excess any sugar or caffeine. My stress level is moderate, but not bad at all.
