So i have been hyper aware of my heart lately and i lost a ton of weight, from 260 to 150. I can feel my heart often now since i am skinny. My question is, when i stand up, it feels like my heart takes a few normal beats then speeds up and slows down, it almost feels like my heart is lagging, not skipping or stopping, but it slows down then speeds up to match my movements. I am not sure if my heart actually slowed down, since my resting hr is usually mid 70's and i am expecting it instantly raise even though it probably needs a second to respond.
I have had this feeling for years and had notated it on my 48hr monitor, but when it came back, they said they did not notice anything during that "event"
