The ECG in Figure-1 was obtained from an 18-year old woman — who moments before been resuscitated from out-of-hospital cardiac arrest. Does this ECG in Figure-1 provide clue(s) to the etiology of this patient's cardiac arrest? I suspected the answer resides in the reason why an 18-year woman might have a cardiac arrest.
