Wolff-Parkinson-White Syndrome

ECG Features

Figure 1: ECG Strip[1]

Wolff-Parkinson-White (WPW) Syndrome is a pre-excitation syndrome caused by "early activation of the ventricles due to impulses bypassing the AV node via an accessory pathway."[2]

Clinical Significance[4]

  • WPW syndrome can first appear any time from childhood to middle age, and presentation of symptoms varies by patient age.
  • Symptoms of WPW syndrome range in severity from moderate chest discomfort or palpitations to severe cardiopulmonary compromise and cardiac arrest.
  • Treatments of WPW syndrome include radiofrequency ablation of the accessory pathway, antiarrhythmic drugs, and AV nodal blocking drugs.
