Again convulsions were noted, head slumped to side, LOC lasted a little longer than initial episode. Once regained consciousness endorsed blurry vision (vision blurred), numb ears - kept slowly grabbing for ears (hypoaesthesia) (slow, uncoordinated movements) to see if they felt normal yet. Stated difficulty swallowing (dysphagia) (Latency: same day) and that that had never happened with syncopal episodes before.   Reportedly, Patient has been syncopal multiple times for vaccines over the last four years however never before then/in childhood so ice packs, fan, and alcohol swabs were readily available for sensory distraction. MD (Doctor of Medicine) to bedside to assess, exam WNL (within normal limits). Vitals WNL (BP and HR (heart rate)) though BP (blood pressure) extremely difficult to obtain due to running 'quiet' (could not be heard on manual BP). Patient monitored x 10 minutes and assisted to feet. Denied dizziness, vision impairment while standing. Left clinic independently. Of note, patient had never received Moderna before. Has endorsed syncopal episodes to 'flu shot' in past but unsure of brand. Syncope in setting of vaccinations new as of four years ago, no issues prior to that historically.
