AB  - Supraventricular  tachycardias  (SVTs)  include  all  tachyarrhythmias  that  either  originate  from  or  incorporate  supraventricular  tissue  in  a  reentrant  circuit.  The  ventricular  rate  may  be  the  same  or  less  than  the  atrial  rate,  depending  on  the  atrioventricular  (AV)  nodal  conduction.  The  term  paroxysmal  supraventricular  tachycardia  (PSVT)  refers  to  a  clinical  syndrome  characterized  by  a  rapid,  regular  tachycardia  with  an  abrupt  onset  and  termination.  Approximately  two-thirds  of  cases  of  PSVT  result  from  AV  nodal  reentrant  tachycardia  (AVNRT).  Orthodromic  AV  reentrant  tachycardia  (AVRT),  which  involves  an  accessory  pathway  (AP),  is  the  second  most  common  cause  of  PSVT,  accounting  for  approximately  one-third  of  cases.  The  term  Wolff-Parkinson-White  (WPW)  syndrome  designates  a  condition  comprising  both  preexcitation  and  tachyarrhythmias.  Atrial  tachycardias,  which  arise  exclusively  from  atrial  tissue,  account  for  approximately  5%  of  all  cases  of  PSVT.1  The  purpose  of  this  chapter  is  to  review  the  mechanism,  clinical  features,  and  approach  to  diagnosis  and  treatment  of  patients  with  AVNRT  and  AP-mediated  tachycardias  (including  WPW  syndrome).  Particular  attention  is  focused  on  reviewing  management  guidelines  developed  by  the  American  Heart  Association  (AHA),  American  College  of  Cardiology  (ACC),  and  Heart  Rhythm  Society  (HRS;  formerly  known  as  the  North  American  Society  of  Pacing  and  Electrophysiology).1  We  will  also  provide  a  brief  overview  of  atrial  tachycardia.
