Progression of clinical and electrophysiological events in Case 2.
Time | EEG (intracranial) | EKG | Respiration | Clinical (out of camera range; audio only) |
---|---|---|---|---|
Event 1 | ||||
9.32.04 | Baseline | 132bpm | N/A | No complaints, asks to go to the bathroom; Registered Nurse (RN) observes patient sit on toilet (for safety) |
19:44:36 | Abrupt theta-delta, progressed to diffuse delta | 120bpm, later obscured by artifact | N/A | Patient heard falling in bathroom at 19:44:50. RN assumes seizure |
19:44:50 | Suppression | 84bpm | N/A | Unresponsive |
19:45:05 | Diffuse delta-theta, with intermittent generalized suppression, then diffuse theta | 84bpm | N/A | Patient initially unable to follow commands, moving, some verbalization |
19.45.52 | Diffuse theta | 84bpm | Deep breathing at 42 brpm heard briefly | Following commands |
19:49:10 | Return to baseline | Heart rate 144 BPM | N/A | Asks to lie down; asks for water; complains of left leg numbness. Noted to be cold and clammy. Denied shortness of breath or headache. |
Event 2 | ||||
20:00:17 – 20:02:00 | Baseline | 144bpm | N/A | Patient feels cold to touch; reliable BP unobtainable. Patient states he feels “a little light and hot” |
20:02:16 | Baseline | 144bpm | N/A | Patient feels “clammy and wet”; RN asks patient to stay still. Conversing. |
20:02:47 – 20:03:00 | Transition to diffuse theta slowing | 132bpm | 42brpm | RN trying to help patient sit up |
20:03:33 – 20:03:56 | Diffusely slow (theta/delta) – progresses to diffuse delta | 102bpm | 42brpm, moaning | RN encourages patient to get up from floor with assistance. Patient feels hot, drinks water. |
20:03:57 | Marked generalized EEG suppression | 60bpm, then progressive bradycardia and idioventricular rhythm | N/A | Unresponsive; RN assumes seizure |
20:08:37 | Marked generalized EEG suppression | Intermittent ventricular complexes | 2brpm Face briefly seen on video |
Unresponsive. RN assessing patient, weak pulse noted. RN administers O2 via mask/manual ventilation (video/audio available at this point) |
20:09:00 – 20:13:00 | No data | No data | No data | Cardiopulmonary resuscitation (CPR) begun at the end of this this period |
