I45.6: Pre-excitation syndrome
The heart’s electrical currents may be flowing to the heart via an additional route. So your heart is sometimes beating too quickly.
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 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.
The heart’s electrical currents usually only flow in one direction: from the atria to the ventricles. In your case there is an additional route for the currents. There are then at least 2 routes for the currents: the normal route and the additional route. As a result, the currents may also flow back to the atria. This is confusing the heart’s normal electrical activity. The heart is then sometimes unable to beat as it should. It may then beat far too quickly. If the heart beats too quickly, it may cause problems.

- V: Tentative diagnosis
