How is WPW Treated?

Treatment depends on the type and frequency of arrhythmias, associated symptoms such as syncope, and presence of structural heart disease. Typically a physician will recommend an ablation procedure to further define the characteristics of the accessory pathway, and ultimately, to eliminate the pathway entirely.

  • Observation - If you have no symptoms, you may not require treatment. Your doctor may choose to have regular follow-up without treatment.
  • Medications - A variety of drugs are available to treat arrhythmias. Because everyone is different, it may take trials of several medications and doses to find the one that works best for you. It is important to know:
    • The names of your medications
    • What they are for
    • How often and at what times to take them
  • Ablation - In people with WPW and symptoms of palpitations or syncope, an ablation procedure is recommended for two reasons: 1) to prevent symptom recurrence and 2) to prevent sudden cardiac death. During ablation, either heat (thermal) or cryoenergy (freeze) is delivered through a catheter to “destroy” the abnormal pathways.
