AB CASE  STUDYA  38-year-old  man  has  been  experiencing  palpitations  and  headaches*.  He  enjoyed  good  health  until  1  year  ago  when  spells  of  rapid  heartbeat  began.  These  became  more  severe  and  were  eventually  accompanied  by  throbbing  headaches  and  drenching  sweats.  Physical  examination  revealed  a  blood  pressure  of  150/90  mm  Hg  and  heart  rate  of  88  bpm.  During  the  physical  examination,  palpation  of  the  abdomen  elicited  a  sudden  and  typical  episode,  with  a  rise  in  blood  pressure  to  210/120  mm  Hg,  heart  rate  to  122  bpm,  profuse  sweating,  and  facial  pallor.  This  was  accompanied  by  severe  headache.  What  is  the  likely  cause  of  his  episodes?  What  caused  the  blood  pressure  and  heart  rate  to  rise  so  high  during  the  examination?  What  treatments  might  help  this  patient?
