I44.3: Other and unspecified atrioventricular block

The heart’s electrical impulses to your ventricles are not being transmitted normally.

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.

Your heart’s electrical impulses from your atria to your ventricles are being transmitted abnormally. As a result, your heart may skip a beat every now and then. The heart may also beat very slowly.

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