1. An apparatus for providing therapy to the heart of a subject, comprising:
- a tachyarrhythmia detector means for detecting tachyarrhythmia of said heart;
a current generator;
an electrode system means connectable for delivering current from said current generator in vivo to the parasympathetic nervous system of said subject and for delivering current from said current generator in vivo to the sympathetic nervous system of said subject; and
control means for causing said current generator, upon detection of tachyarrhythmia by said tachyarrhythmia detector, to emit a first, pulsed current via said electrode system to the parasympathetic nervous system in order to activate said parasympathetic nervous system and to emit a second current via said electrode system to the sympathetic nervous system for blocking said sympathetic nervous system.

Abstract
A device for heart therapy has a tacharrythmia detector unit, a control unit and a current generator. The current generator controlled by the control unit emits via an electrode system a first, pulsed current to a physiological representative of the parasympathetic nervous system in order to activate same in response to detection of an impending or established arrhythmia. The current generator is further caused by the control unit, in the event of tachyarrythmia detection to emit, via the electrode system, a second current to a physiological representative of the sympathetic nervous system in order to block same.

15. A method for providing therapy to the heart of a subject, comprising the steps of:
-
detecting tachyarrhythmia of said heart; and upon detection of tachyarrhythmia, delivering a first, pulsed current in vivo to the parasympathetic nervous system of said subject in order to activate said parasympathetic nervous system and delivering a second current in vivo to the sympathetic nervous system of said subject for blocking said sympathetic nervous system. - View Dependent Claims (16, 17, 18, 19, 20, 21, 24, 25, 26, 27)
