I49.9: Cardiac arrhythmia, unspecified
Your heart is beating irregularly.
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 originates in the right atrium. The heart’s electrical activity triggers the heartbeat. The activity then first spreads in the two atria. The activity then flows via a sort of cable from the atria to the ventricles.
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
