Wolff-parkinson-white Syndrome


Wolff-Parkinson-White (WPW) syndrome is a condition that causes tachycardia (fast heartbeat). A normal heartbeat is about 60 to 100 beats per minute. WPW causes 100 or more heartbeats per minute. WPW develops because an extra piece of heart muscle causes more electrical activity within your heart. WPW can develop for no known reason. Congenital heart disease or a family history of WPW can increase your risk.


Informed consent

is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.


Medicines may be given to slow or regulate your heartbeat.


  • An EKG is a test that measures the electrical activity of your heart.
  • Blood tests may be used to check your thyroid and potassium levels.
  • An x-ray may show if your heart is larger than it should be.
  • Electrophysiologic studies (EPS) test the electrical activity of your heart.


  • Radiofrequency ablation is a procedure used to send energy to the area of your heart that has an electrical problem. The energy causes an area of the heart muscle to scar. This stops the electrical problem and allows your heart to beat normally.
  • Cardioversion is a procedure used to give your heart an electrical shock. The shock may help put your heartbeat back into a normal rhythm. Cardioversion may be needed if other treatments do not work.


You may develop heart failure or low blood pressure. Rarely, WPW can cause shock or death.
