Middle-Aged Women Found Down: Seen in the ED

The patient shows no signs of trauma but is a poor historian so no further details are available. Do her vitals or ECG provide any clues to a Dx?

History of present illness: A woman in her mid-50s is transported from the streets to the emergency department (ED) after being found down without evidence of trauma in front of a business. She is a poor historian and is unsure if she might have fainted or just fallen asleep. She denies chest pain or other complaints but seems quite sleepy.

Vital signs and physical examination:

  • Heart rate: 52 beats/min
  • Blood pressure: 115/73 mm Hg
  • Respiratory rate: 12 breaths/min with O2 saturation of 94% on room air
  • Neurologic examination is nonfocal but she is uncooperative and so it is limited.
  • ECG findings are shown here
