The document discusses various EEG and CFM traces from infants. It notes features like suppressed or abnormal CFM traces with seizures, bursts, or artifacts visible on the EEG. Specific traces show improvements over time from severely abnormal to normal as the infants recover with treatment. The document suggests full EEG exams are needed when CFM traces are suspicious of seizures but the EEG is not clearly characteristic.

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 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

33. Normal trace initially – second half of trace has artefact

34. Normal amplitude with seizures

35. Severely abnormal trace with seizures

36. Severely abnormal trace with slow seizure discharge

37. Severely abnormal trace with frequent seizures in initially

38. Severely abnormal trace with seizures

39. Severely abnormal trace with high amplitude bursts

40. Moderately abnormal trace with burst suppression pattern improving initially

41. Moderately abnormal trace improving to a normal trace
