Q

What actually is WPW?

A
  • Wolff Parkinson White Syndrome​
    • WPW is an electrical abnormality in the heart that may be associated with supraventricular tachycardia (fast heart rate originating above the ventricles). When you have WPW, along with your normal conduction pathway, you have an extra pathway called an accessory pathway.
