Hey guys. I was wondering what your opinion was on this. Has anyone ever had a feeling that I can only describe as it feels like too much blood is trying to be pumped through your heart at one time? This only happens maybe a couple times a year or so, but it's really strange. It feels like the heart tightens for a second and kind of "glub glubs" in a weird beat kind of way and then everything is back to normal. It's starting to worry me but I just thought I would see what you guys say. Thanks a lot.
