1. An arrhythmia treatment system comprising:

  • sensor means adapted for implantation in a patient for sensing a physiological characteristic which exhibits a change upon the onset of cardiac arrhythmia and for generating an electrical signal corresponding to said physical characteristic;

    treatment means contained in a housing adapted for implantation in a patient, said treatment means adapted to be connected in vivo to said sensor means to receive said electrical signal therefrom for initiating an arrhythmia treatment sequence, including releasing a treatment pulse in vivo to said patient via electrodes adapted for implantation in said patient, in response to said change in said physical characteristic;

    means in communication with said treatment means for informing said patient, substantially simultaneously with the initiation of said arrhythmia treatment sequence, that said arrhythmia treatment sequence has been initiated; and

    means in communication with said treatment means and operable by said patient for optionally stopping said arrhythmia treatment sequence before releasing said treatment pulse.
