Fast heart rate when standing and sometimes SOB
Hello everyone! I just wanted to post and see if anyone else has had the same problems as me. When I stand up from lying down my heart rate shoots up 40 plus beats. I will have a heart rate of 60 and then when I stand it will hit 120. This makes my chest feel tight and I can feel my heart race. It will eventually within 10 minutes subside but I do not know what it could be from. I have wondered if it could be POTS because I have the shortness of breath upon standing and the chest tightness. I am not sure what it could but it can be really frustrating. Sometimes also my heart feels like it wants to beat hard. Anything input would help, Thanks!
