AB ESSENTIALS  OF  DIAGNOSISTwo  classic  features  of  Wolff-Parkinson-White  (WPW)  pattern  on  ECG  are  short  PR  interval  and  wide,  slurred  QRS  complex  due  to  manifest  preexcitation  (delta  wave).Most  patients  with  WPW  pattern  do  not  have  clinical  history  of  arrhythmia  but  have  a  higher  risk  of  sudden  cardiac  death  due  to  rapidly  conducted  atrial  fibrillation  through  the  accessory  pathway.  Risk  factors  include  age  younger  than  20,  history  of  tachycardia,  and  rapid  conduction  properties  at  electrophysiologic  testing.
