Does anyone else have this issue? If I sit upright at my desk more than a couple of hours when I get up my heart starts racing I get PVC's, feel cold, and feel awful shaky dizzy. After about 30-45 minutes of moving around I feel better. I know I know I should get up and move around more during the day but my job requires that I sit for long periods of time. I guess I just going to have to force myself to move around more.... I realize others cant even get out of bed so I am thankful to be able to move around and lead a fairly "normal" life but I hate it when it happens. It scares me. I have had multiple tests done since my diagnoses in 2009 but it still scares me.......... Anyone else experience similar issues? End of rant I guess thanks for listening. I don't post much but I do love to read about others and it is nice to know I am not alone.
