I found this ref on Stokes-Adams attack:

[...]
Simultaneous EEG and ECG tracings were obtained during the syncopal
attack. These showed that she was in normal sinus rhythm with a rate
of 70 bpm prior to her loss of consciousness. Her cardiac rhythm
quickly degenerated into complete cardiac standstill after a couple of
junctional escape beats. This lasted for 27 seconds. During the period
of sinus rhythm, her EEG tracings showed prominent moderate voltage of
10 per second alpha rhythm of symmetrical distribution with no
consistent focal changes. Ten seconds following ventricular
standstill, this background EEG rhythm was replaced by a three per
second burst of high voltage delta activity in all areas. This was
followed six seconds later, by a flat record of no electrical activity
in all the 20 scalp electrodes. It was during this period that the
patient was noted to have lost consciousness.

"was noted to have lost consciousness", eh.
