Description
Standing up is something most of us take for granted; we've been doing it since childhood. Our bodies automatically adjust to the pull of gravity by increasing vascular tone, heart rate and cardiac output. POTS symptoms are sometimes correctable if an underlying cause is discovered. Researchers are attempting to identify and treat the mechanisms and causes of POTS.
