Diagnosis

Your doctor will likely recommend heart tests to diagnose WPW syndrome, such as:

  • Electrocardiogram (ECG). Small sensors attached to your chest and arms record electrical signals as they travel through your heart. Your doctor can look for patterns among these signals that indicate the presence of an extra electrical pathway in your heart.
  • Portable ECG. Using a portable ECG device at home provides more information about your heart rate. A Holter monitor records your heart activity for 24 hours. An event recorder monitors heart activity when you experience symptoms of a fast heart rate.
  • Electrophysiological testing. Thin, flexible tubes (catheters) tipped with electrodes are threaded through your blood vessels to various spots in your heart. The electrodes can precisely map the spread of electrical impulses during each heartbeat and identify an extra electrical pathway.
