NOVACODE 0

Baseline ECG Suppression Codes

0.0

No suppression codes

0.1

ECG not availiable

0.2

Inadequate quality or missing leads

  • 0.2.1 Inadequate quality
  • 0.2.2 Missing leads

0.3

Lead connection interchange.

  • 0.3.1 RA/RL Connection interchange (ECG Uncodable)
  • 0.3.2 Other lead Connection interchanges (correction made and ECG coded)

0.4

QRS >= 120 ms (code 2.4, 3.1, 3.2, 3.3, and 1.9; code 0.4 suppresses ST-T scores and code 5; code 4 with code 3.2 suppresses code 8)

0.5

Atrial fibrillation (AF) or atrial flutter (AFL) (suppresses code 2, 7, and 9; codes 0.5 with code 1.5.1 (atrial flutter) suppresses ST-T scores and code 5.5, 5.6, and 5.8)

0.6

Electronic pacemaker (code 0.6 with code 1.6.1 suppresses all other codes; code 0.6 with code 1.6.2 suppresses codes 1.0 - 1.5, code 2, code 7, and code 9)

0.7

Other suppression codes (use code 0.7 to indicate absent P wave and PR measurements associated with codes 2.2.1 and 2.3)

0.8

Uncertain P wave detection (Flags rhythm code 1.9.1)
