Wolff-Parkinson-White (WPW) is a condition in which the heart has an extra electrical pathway, also called an accessory pathway. Because of this extra pathway, electrical signals in the heart bypass the normal electrical pathway. The heart has 4 chambers that work like a pump. The atria are the 2 top chambers.
