so when i sit down fast, kneel down, bend down, stand up or lay down my heart starts to beat very forcefully and i can feel it in my throat and chest and i feel short of breath. but my heart rate does NOT increase it stays the same or gets slower just each beat is extremely forceful?
i get the exact same thing, it beasts harder and slower for a few seconds. i also find its worse if ive been sedentary for a while. if you go for a long walk then do the same thin ii bet it doesnt do it as much
