1. A method for classifying and treating an arrhythmia, comprising:

  • implementing a programmed arrhythmia recognition routine to classify the arrhythmia before treating the arrhythmia, wherein implementing the programmed arrhythmia recognition includes;

    sensing a characteristic of a ventricle before delivering a diagnostic neural stimulation;

    delivering the diagnostic neural stimulation to diagnose the arrhythmia;

    sensing the characteristic of the ventricle while delivering the diagnostic neural stimulation; and

    using the sensed characteristic of the ventricle before and during the diagnostic neural stimulation to classify the arrhythmia as either a supraventricular tachyarrhythmia (SVT) or a ventricular tachycardia (VT); and

    implementing a programmed response to classifying the arrhythmia after completing the programmed arrhythmia recognition routine, including;

    delivering a VT therapy to treat the VT when the classified arrhythmia is the VT; and

    either delivering no therapy or delivering an SVT therapy to treat the SVT when the classified arrhythmia is the SVT,wherein;

    the VT therapy and the SVT therapy each have distinct protocols from the diagnostic neural stimulation and are delivered after completion of the programmed arrhythmia recognition routine; and

    the SVT therapy includes myocardial stimulation therapy.
