    How does a defibrillator work, what's inside?
    And how does it affect the body, ameliorate a heart attack?

    Hoping there's a cardiologist in this group, as well as engineers -

    OUside of the electronics that prevent it from discharging into a
    working heart, it is just a large capacitor . You hear on the TV shows
    the doctor calling out 'Charging 200' or Charging 400. That is the
    ammount of power the capacitor is charged to . The heart will often go
    into fiberlation which mostly means it is not contracting and letting
    loose in a normal manner but just randomly viberating. The Capacitor
    discharge clamps the heart mussel and lets it restart in a normal beat
    if it works.
