Wolff-Parkinson-White (WPW) syndrome

Complications

For many people, WPW syndrome doesn't cause serious problems. But complications can occur. It's not always possible to know your risk of serious heart-related events. If WPW syndrome is untreated — particularly if you have other heart conditions — you might have:

  • Fainting spells
  • Fast heartbeats
  • Rarely, sudden cardiac arrest
