1. A system for predicting and preventing cardiac arrhythmias for use in combination with an implantable arrhythmia treatment device, said system comprising:
- means for monitoring the neural activity of a patient to predict an impending arrhythmia;
means for taking actions in said implantable arrhythmia treatment device prior to an initial irregular beat of said impending arrhythmia to prevent the initial irregular beat or prepare for said arrhythmia upon said means for monitoring detecting a predetermined change in said neural activity.

Abstract
A system for predicting and preventing cardiac arrhythmias for use in combination with an implanted arrhythmia treatment device comprising means for sensing the neural activity of a patient and triggering the implanted arrhythmia treatment device to take preventative and curative actions for an impending arrhythmia upon an elevation of the neural activity. The preventative actions include overdrive pacing of the heart, charging a defibrillator capacitor, activating an alternative cardiac sensing scheme, and applying an anti-arrhythmia drug to the heart of a patient.

13. A system for predicting and preventing cardiac arrhythmias for use in combination with an implantable arrhythmia treatment device, said system comprising:
-
means for monitoring the sympathetic neural activity of a patient to predict an impending arrhythmia; means for monitoring the ECG of the heart of the patient; means for detecting the concurrence of both a change in the sympathetic neural activity and an abnormal characteristic of said ECG, and generating a concurrence output signal; means for taking actions in said implantable arrhythmia treatment device prior to an initial irregular beat of said impending arrhythmia to prevent the initial irregular beat or prepare for said arrhythmia upon the generation of said concurrence output signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
