System to treat AV-conducted ventricular tachyarrhythmia

摘要

Various aspects of the present subject matter provide devices and methods to treat AV-conducted ventricular tachyarrhythmia (AVCVT). According to various embodiments of the method, an AVCVT is sensed, an IVC-LA fat pad is stimulated when the AVCVT is sensed to block AV conduction, and bradycardia support pacing is provided while the IVC-LA fat pad is stimulated. Other aspects and embodiments are provided herein.

主权项

1. An implantable medical device, comprising:
pacing circuitry configured to provide bradycardia support pacing to maintain a minimum heart rate; an atrial rate detector configured to detect an atrial rate; a neural stimulation circuit configured to apply neural stimulation to an interior vena cava-left atrium (IVC-LA) fat pad; and a controller operably connected to the pacing circuitry, the atrial rate detector and the neural stimulation circuit, wherein the controller is configured to control the neural stimulation circuit to deliver neural stimulation to the IVC-LA fat pad on condition that the detected atrial rate exceeds a programmable threshold programmed into the implantable medical device.
