AB In  POTS,  orthostatic  symptoms  (tremulousness,  lightheadedness,  palpitations,  visual  disturbances,  weakness,  fatigue,  anxiety,  hyperventilation,  nausea)  develop  with  a  significant  tachycardia  (an  increase  of  30  beats/minute  or  more  or  a  heart  rate  of  120  beats/minute  or  more)  within  10  minutes  of  standing,  in  the  absence  of  postural  hypotension  or  an  autonomic  neuropathy.  POTS  is  more  common  in  women  than  men  and  in  patients  between  20  and  50  years  of  age.  Other  medical  problems  causing  a  tachycardia  must  be  excluded.
