ABC-VT score

A new score to help predict adverse events in patients with frequent premature ventricular contractions (PVCs).

In the study predictors of adverse remodeling were:

  • non-sustained VT) (odds ratio [OR], 5.3)
  • longer PVC coupling interval of at least 500 ms (OR, 4.7)
  • PVC burden (OR, 4.4 for >20%; OR, 3.5 for 10% to 20%)
  • Superiorly directed PVC axis (OR, 2.7)

These parameters were scored and scores from 0 to 4 were classified as low risk; from 5 to 8, intermediate risk; and from 9 to 12, high risk.


  1. Doesn’t include patients with low coupling interval prone for R on T phenomena
  2. PVC dispersion not included in score
  3. LV remodelling assessment by EF and correlating with endpoint may not be fool proof
