Neural stimulation system for cardiac fat pads

A method, comprising:

• providing a feedback signal indicative of at least one physiological signal;
• and
• providing a neural stimulation therapy responsive to the feedback signal, including:
• stimulating an SVC-AO cardiac fat pad to change ventricular contractility of the heart without changing heart rate or inducing an arrhythmia, the SVC-AO fat pad being located proximate to a junction between a superior vena cava and an aorta;
• and
• stimulating a PV cardiac fat pad associated with an sinoatrial (SA) node to change a sinus rate of the heart without changing AV conduction time, the PV cardiac fat pad being located proximate to a junction between a right atrium and right pulmonary veins;
• and
• stimulating an IVC-LA cardiac fat pad associated with an atrioventricular (AV) node to change the AV conduction time of the heart without changing the sinus rate, the IVC-LA cardiac fat pad being located proximate to a junction between an inferior vena cava and a left atrium.

A method for providing specific pacing effects to a heart, comprising:

• changing ventricular contractility of the heart without changing heart rate or inducing an arrhythmia;
• and
• changing a sinus rate or an AV conduction time of the heart, wherein changing the sinus rate does not change the AV conduction time and changing the AV conduction does not change the sinus rate,
• wherein changing the ventricular contractility includes stimulating an SVC-AO cardiac fat pad located proximate to a junction between a superior vena cava and an aorta,
• wherein changing the sinus rate includes stimulating a PV cardiac fat pad located proximate to a junction between a right atrium and right pulmonary veins, and
• wherein changing the AV conduction time includes stimulating an IVC-LA cardiac fat pad located proximate to a junction between an inferior vena cava and a left atrium.
