Techniques for applying, configuring, and coordinating nerve fiber stimulation
First Claim
1. A method for treating a subject in which a first control unit is implanted and configured to apply, from a first implantation site within the subject, only when a heart rate of the subject is within a first set of values, pulses to a heart of the subject responsive to a sensed electrical parameter of the heart, the pulses selected from the group consisting of:
- pacing pulses and anti-arrhythmic energy, the method comprising;
configuring a second control unit to apply, at a second implantation site within the subject, only when the heart rate is within a second set of values, a current that increases parasympathetic tone of the subject and affects a heart rate of the subject, the second implantation site selected from the group consisting of;
a vagus nerve, an epicardial fat pad, a pulmonary vein, a carotid artery, a carotid sinus, a coronary sinus, a vena cava vein, a right ventricle, and a jugular vein; and
configuring at least one of the control units to coordinate an aspect of applying the pulses with an aspect of applying the current, wherein the first and second control units are not under common control,wherein the first and second sets of values are non-overlapping.

Abstract
Apparatus is provided including an implantable sensor, adapted to sense an electrical parameter of a heart of a subject, and a first control unit, adapted to apply pulses to the heart responsively to the sensed parameter, the pulses selected from the list consisting of: pacing pulses and anti-arrhythmic energy. The apparatus further includes an electrode device, adapted to be coupled to a site of the subject selected from the list consisting of: a vagus nerve of the subject, an epicardial fat pad of the subject, a pulmonary vein of the subject, a carotid artery of the subject, a carotid sinus of the subject, a coronary sinus of the subject, a vena cava vein of the subject, a right ventricle of the subject, and a jugular vein of the subject; and a second control unit, adapted to drive the electrode device to apply to the site a current that increases parasympathetic tone of the subject and affects a heart rate of the subject. The first and second control units are not under common control. At least one of the control units is adapted to coordinate an aspect of its operation with an aspect of operation of the other control unit. Other embodiments are also described.
