1. A device, comprising:
- a controller;
an event detection sensor adapted to cooperate with the controller to detect a supraventricular arrhythmia event;
a neural stimulator adapted to stimulate a neural target to elicit a sympathetic response through sympathetic stimulation or parasympathetic inhibition, the controller being adapted to control the neural stimulator to stimulate the neural target in response to the detected supraventricular arrhythmia event for treating the detected supraventricular arrhythmia event; and
a feedback sensor, distinct from the event detection sensor, adapted to sense a physiological response to stimulation of the neural target, the controller being adapted to make a comparison of the sensed physiological response to a target range for the response, and to use the comparison to adjust a stimulation intensity of the stimulation for treating the detected supraventricular arrhythmia event, wherein the feedback sensor is selected from the group consisting of a respiration sensor, a blood pressure sensor, and a nerve traffic sensor.

Abstract
In various method embodiments, a supraventricular arrhythmia event is detected, and a supraventricular arrhythmia treatment, including neural stimulation to elicit a sympathetic response, is delivered in response to a detected supraventricular arrhythmia event. Some embodiments detect a precursor for a supraventricular arrhythmia episode, and deliver prophylactic neural stimulation to avoid the supraventricular arrhythmia event. Some embodiments detect a supraventricular arrhythmia episode, and deliver therapeutic neural stimulation for the supraventricular arrhythmia event.
