A 16-year-old female was admitted to the coronary care unit after an aborted sudden cardiac death. The patient was awakened to answer a telephone call and suddenly collapsed. The fall was witnessed and a rapid 911 call allowed the para- medics to arrive within 5 minutes. The patient was in VF and was successfully defibrillated with one shock. She remained comatose and was intubated and transported to the hospital.
On physical exam she was intubated and withdrew to painful stimuli. Her pupils were dilated, but reactive to light symmetrically. Her past medical history is remarkable for 3 brief fainting episodes. She was not using any prescription medication. The mother denied knowledge of substance abuse. Her family his- tory is notable for a sister who died suddenly at the age of 20.
