I49.8: Other specified cardiac arrhythmias
Your heart is beating irregularly, too quickly or too slowly.
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 normally begins at a site in your right atrium. The electrical activity spreads further around the heart via a type of cable.
The electrical activity may not spread in a normal way, or it may begin at a different location in the heart. There may also be extra heart beats. Your heart may then beat irregularly, too quickly or too slowly.
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
- B: Both sides
