Cardiac therapy system
First Claim
1. A cardiac therapy system controlled by activity signals of the autonomous nervous system in a patient'"'"'s body which constitute a measure for the patient'"'"'s cardiovascular output requirement, for use with a conventional cardiac pacemaker circuit, the system comprising:
- pickup means for detecting at least the autonomous nervous system activity signals in the patient'"'"'s body;
control means for generating control signals as a function of time and/or intensity of the autonomous nervous system signals picked up in the patient'"'"'s body by the pickup means;
neurostimulator means for changing vascular resistance by nerve stimulation of the patient in adaptation to the patient'"'"'s intracardial output requirement, in response to control signals from the control means;
arrythmia suppressor means for generating anti-arrhythmia stimulation pulses to the patient'"'"'s heart which are controlled by control signals from the control means;
andpump assist means for assisting the pumping of the patient'"'"'s heart in response to control signals from the control means.

Abstract
A cardiac therapy system for use with a conventional cardiac pacemaker ciit is controlled by activity signals of the autonomous nervous system (ANS) in a patient'"'"'s body which constitute a measure for the patient'"'"'s cardiovascular output requirement. The system includes pickup circuitry for detecting at least the autonomous nervous system activity signals in the patient'"'"'s body, a control circuit for generating control signals as a function of time and/or intensity of the autonomous nervous system signals picked up in the patient'"'"'s body, a neurostimulator for changing vascular resistance by nerve stimulation of the patient in adaptation to the patient'"'"'s intracardial output requirement, in response to control signals from the control circuit, an arrythmia suppressor for generating anti-arrhythmia stimulation pulses to the patient'"'"'s heart which are controlled by control signals from the control circuit, and a pump assist for assisting the pumping of the patient'"'"'s heart in response to control signals from the control circuit.
