Patent ID: 7555341

Claim:
An implantable medical device, comprising: at least one port, each port being adapted to connect at least one lead that has at least one electrode; a sensing circuit connected to the at least one port to sense atrial activity and ventricular activity for use in determining an Atrioventricular-Conducted Ventricular Tachyarrhythmia (AVCVT) event; a neural stimulation circuit connected to the at least one port to selectively apply a neural stimulation signal to an inferior vena cava-left atrium (IVC-LA) fat pad located between an inferior vena cava and a left atrium; a pacing circuit connected to the at least one port to provide bradycardia support pacing to maintain at least a programmable minimum heart rate; and a controller connected to the sensing circuit, the neural stimulation circuit and the pacing circuit, the controller being adapted to detect the AVCVT event using a comparison of the atrial activity and the ventricular activity sensed by the sensing circuit to determine that the atrial activity is tracking the ventricular activity, apply the neural stimulation signal to the IVC-LA fat pad in response to and during the detected AVCVT event to block atrioventricular (AV) conduction to terminate the AVCVT event, and provide bradycardia support pacing when the neural stimulation signal is applied to the IVC-LA fat pad.
