Any one eva experianced a feeling like....... your heart just become solid and to large in your chest right after palp's stops or any time?

Another thing I noticed is that my whole right arm moving to beat of my heart thumping in my chest.....I was not scared of what i was noticing I was just amused by it all.

I wonder what I should pay attention to and what to ignore when I have palps but I dont worry or get scared or anxious in anyway. I forgot to mention these sensation to my Dr just in case thay were a more serious sign but I'm kind of interested in thw way other people experiance palps.
