I49.5: Sick sinus syndrome
Your heart’s pacemaker is not working properly.
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 pacemaker for our heartbeat is in the heart’s right atrium. The pacemaker normally emits regular, small electrical currents for the heart. The electrical currents trigger the heartbeat.
Your pacemaker is not working properly. As a result, your heart may beat too quickly, too slowly, or irregularly.
On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.
- G: Confirmed diagnosis
- V: Tentative diagnosis
- Z: Condition after
- A: Excluded diagnosis
- L: Left
- R: Right
