  1. Are these seizures? The EEG is not conclusive but the CFM is suggestive of seizures

  2. Normal CFM and continuous EEG

  3. Trace from infant with non ketotic hyperglycinaemia – note very high amplitude CFM and frequent high voltage EEG bursts

  4. Severe suppression of CFM with low voltage EEG bursts but no clear EEG seizure pattern

  5. Severe suppression of CFM with low voltage bursts on EEG

  6. Repetitive seizures – CFM hard to classify – often changes to severe suppression after treatment with anticonvulsants

  7. Very suppressed CFM with bursts evolving to seizures

  8. Probable seizure but EEG not characteristic – CFM has normal amplitude

  9. Severe suppression of CFM with high voltage bursts on EEG

  10. Variation in CFM amplitude possibly due to change in sleep/awake state; EEG moderately discontinuous

  11. Artefact – CFM/EEG cannot be classified – initial part of trace appears normal

  12. Very high voltage seizure discharge – CFM moderately suppressed

  13. Probable movement artefact rather than seizure - CFM otherwise normal

  14. Exaggerated sleep wake cycling pattern – common during recovery phase – note movement artefact with nursing care

  15. Gross artefact - Note abnormal impedance in lower half of slide – CFM trace cannot be interpreted

  16. Gross artefact probably due to detached electrodes Note abnormal high impedance in lower half of slide – CFM trace cannot be interpreted

  17. CFM suspicious of frequent brief seizures but EEG not characteristic – full EEG exam needed

  18. Rapidly recovering CFM trace – EEG initially moderately discontinuous

  19. Initial very suppressed CFM – sudden increase in amplitude probably due to seizures

  20. Severely suppressed CFM with some low voltage bursts on EEG and artefact due to handling of infant

  21. Gross ECG artefact elevating CFM baseline – seizures are also present

  22. Note seizures – CFM baseline elevated due to ECG artefact

  23. Note ECG artefact causing elevation of CFM trace

  24. CFM suspicious of intermittent seizure but not obvious on EEG

  25. Probable pulse artefact which is abolished by change of position of head

  26. Frequent seizures

  27. Seizure on severely suppressed background with frequent low voltage bursts

  28. ECG artefact resulting in CFM appearing falsely reassuring

  29. Frequent high voltage sharp waves on EEG causing seizure like elevation of CFM

  30. Normal continuous EEG activity and normal CFM with some sleep/wake pattern

  31. Moderately abnormal CFM with artefact due to handling marked

  32. Moderately abnormal CFM; note compressed scale of EEG trace
