Just to clarify, cardiologists and cardiac electrophysiologists use the term "sudden death" to define a specific cardiac event namely ventricular fibrillation cardiac arrest. There are "sudden death" survivors who spontaneously revert back to a more stable rhythm (rare of course but it happens) or those who have "aborted sudden death" due to a defibrillator discharge or other intervention. I know it sounded like a "duh" but that's the lingo and there are recoveries from SCD. Regards, bp
