1. A system for predicting sudden cardiac death episode, comprising:

  • a measuring device that measures intra-cardiac impedance;

    a derivation module that derives a physiologic cardiac parameter from the measured impedance, the derived physiologic cardiac parameter comprising an ejection fraction;

    a trending module that trends the derived parameter over spaced time intervals to create trend data; and

    an analyzing module that analyzes the trend data to predict the onset of a sudden cardiac death episode.
