I did an internet search on palpitations and dizziness and there were mostly anxiety hits. I have always been a worrier but I have never had a problem with anxiety and panic attacks. Until POTs started, I never noticed my heart beating in my life. Here are some situations where my symptoms show up. I was curious if you experience the same and whether or not you think it is related to dysautonomia or anxiety. In what type of situations are your symptoms gauranteed to flare up? It would be neat if there were certain things that we find we all have in common that could possibly lead to clues as to what is going on with our bodies! Does anyone else get wicked palps and dizzy after laughing? Does sitting at a cookout in the heat make you dizzy and shaky? Do stairs/mild exertion cause skipped beats/palps? Most sites mention that sitting down relieves symptoms. I have symptoms laying/sitting and standing...just different symptoms. How about you? Is the tachy worse in the morning for you? This morning I went from 44-140 in a minute but tonight I am going from 44-90...not as bad. Some nights it only goes up 10 bpm or so but the morning is always a huge jump. In the morning, when I feel the racing standing up, if I bend at the waste or kneel I can drop 80 bpm within seconds....how about you? Is anyone else on this board a shy person? I always have been and wonder if that could be a common thing amongst dysautonomia patients. Anything else you can think of that could be a common thing, let me know. I was a math major. With math, there is always some sort of a definitive answer.....the unknowns of POTs are driving me nuts:) As always - Thanks for your time!
