Polyspikes slow wave complex
From EEGpedia
- Same as Spike slow wave complex, however with 2 or more spikes associated with the slow wave
- Usually the slow wave is of higher amplitude than the spike
- Spike:
- Clearly distinguishable from background activity
- Sharp peak at conventional paper speeds (i.e. 30 mm/sec)
- Duration of 20-70 ms
