ICD-Code I45.6: Pre-excitation syndrome

In your case, the heart’s electrical impulses may be flowing between the atria and the ventricles via an additional route.

The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition.The electrical currents flow through the heart. The heart's electrical activity causes the heart muscle to contract. It begins at a site in your right atrium. Initially the electrical activity spreads to both atria. The electrical activity then flows on via a sort of cable to the ventricles.

In addition to the normal route for your heart’s electrical impulses, there is an additional route for the impulses to travel between your atria and your ventricles. The electrical impulses may travel faster than normal via this route. They may also flow in the wrong direction via this route. This can cause the electrical impulses to become confused. The heart is then unable to beat as it should. It may beat much too quickly.

Additional indicator

On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
