Your Care Instructions

Wolff-Parkinson-White (WPW) syndrome is a heart rhythm problem that causes a very fast heart rate. It happens because you have an extra electrical pathway in your heart. WPW is a congenital heart problem. This means you were born with the problem.

You may have a fast heart rate or feel a fluttering in your chest (palpitations), feel light-headed or dizzy, or faint. When you have these symptoms, it is called an episode. You may never have an episode, rarely have one, or have one once or twice a week.

Very rarely, a WPW episode can trigger a heart rhythm that can cause death.

Your doctor may prescribe medicines to help slow down your heartbeat. Your doctor may also suggest you try vagalmanoeuvres when having an episode of WPW. These are things, like bearing down, that might help slow your heartrate. Bearing down means that you try to breathe out with your stomach muscles but you don't let air out of yournose or mouth. Your doctor can show you how to do vagal manoeuvres. He or she may suggest that you lie down on your back to do them.

In some cases, a procedure called catheter ablation is done.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Take your medicines exactly as prescribed. Call your doctor or nurse call line if you think you are having a problem with your medicine. You will get more details on the specific medicines your doctor prescribes.
  • If your doctor showed you how to do vagal manoeuvres, try them when you have an episode. These manoeuvresinclude bearing down or putting an ice-cold, wet towel on your face.
  • Monitor your condition by keeping a diary of your WPW episodes. Bring this to your doctor appointments. First, you'll need to count your heart rate (take your pulse).
  • After you check your heart rate, write down:
    • How fast or slow your heart was beating.
    • If your heart rhythm was regular or irregular.
    • What symptoms you had.
    • The time of day your symptoms occurred.
    • How long your symptoms lasted.
    • What you were doing when your symptoms started.
    • What may have helped your symptoms go away.
  • If they trigger episodes, limit or avoid alcohol or drinks with caffeine.
  • Do not use over-the-counter decongestants, diet pills, or "pep" pills. They often contain ingredients that make your heart beat faster (stimulants).
  • Do not use illegal drugs, such as cocaine, ecstasy, or methamphetamine, which can speed up your heart's rhythm.
  • Do not smoke. Smoking can make this condition worse. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
