Cardiac Arrest

Alyssa has been suffering with fluttering sensation in her chest and decides to go to the doctor to have it checked out.  While at the office, the doctor gives her a thorough examination and sends her off with a clean bill of health.  As she's getting dressed after the exam, she starts to feel weak and goes into cardiac arrest.  The nurse calls for the doctor who runs in - they get the defibrillator out and zap the unconscious patient back to life.  Alyssa stays in the office for many hours to make sure she doesn't have a recurrence.  Later, as she's finally preparing to leave, she again goes into cardiac arrest and must be resuscitated with the defibrillator once more.  When she comes to, electrodes are placed on her chest and she's monitored for some time before allowed to leave.
