AB Palpitations  are  extremely  common  among  patients  who  present  to  their  internists  and  can  best  be  defined  as  a  “thumping,”  “pounding,”  or  “fluttering”  sensation  in  the  chest.  This  sensation  can  be  either  intermittent  or  sustained  and  either  regular  or  irregular.  Most  patients  interpret  palpitations  as  an  unusual  awareness  of  the  heartbeat  and  become  especially  concerned  when  they  sense  that  they  have  had  “skipped”  or  “missing”  heartbeats.  Palpitations  are  often  noted  when  the  patient  is  quietly  resting,  during  which  time  other  stimuli  are  minimal.  Palpitations  that  are  positional  generally  reflect  a  structural  process  within  (e.g.,  atrial  myxoma)  or  adjacent  to  (e.g.,  mediastinal  mass)  the  heart.
