This has only usually happened during panic attacks (which I get infrequently , now anxiety attacks… that’s 24/7) but starting on Friday I’ve had several episodes of my heart just randomly racing to the point it’s pounding out of my chest. The first time was on Friday at the beach and I couldn’t even get to the beach front because I thought I was dying. (Finally eventually made it and had a blast but was weird it happened as I wasn’t really anxious) 

Saturday we were driving for a few hours and I got beyond sick with a migraine , nausea, shaking, and I kept getting these horrible bursting sensations in my head, I was trembling and spacing out, I switched with my husband who drove the rest of the way because I actually felt I was not able to drive . 

When we arrived I had a blast no anxiety, at night time I could not sleep due to my heart racing and pounding 

Today was the same thing , I was super sick with a migraine , couldn’t talk, felt disconnected and I’m when we finally came home I napped and again my heart was racing and pounding so much so that you could visibly see my chest shaking . 

Nothing is particularly giving me anxiety but it’s starting to concern me that I’m having these weird brief periods of just my heart racing and pounding . This usually only happens with my agoraphobia and inside places that trigger me . I’ve had my heart checked only a couple months ago so it’s perfectly fine except some regurgitation which poses no issue. Has anyone had these periods of their heart just going haywire ?? How many consecutive days ?
