1. Apparatus comprising:
- a monitor, configured to sense one or more physiological parameters;
an electrode device, configured to be coupled to a baroreceptor site of a subject; and
a control unit, configured to detect an episode of non-sinus atrial tachycardia responsively to the one or more sensed physiological parameters, and, responsively to the detection, restore normal sinus rhythm (NSR) of the subject, by;
driving the electrode device to apply a stimulation signal to the baroreceptor site, andconfiguring the stimulation signal to lower a blood pressure of the subject sufficiently to restore the NSR.

Abstract
Apparatus is provided, which includes an electrode device, configured to be coupled to an atrial site of a subject containing parasympathetic nervous tissue, and a control unit. The control unit is configured to, responsively to a detection of an episode of non-sinus atrial tachycardia, restore normal sinus rhythm (NSR) of the subject, by driving the electrode device to apply a parasympathetic stimulation signal to the atrial site, and configuring the parasympathetic stimulation signal to activate the parasympathetic nervous tissue sufficiently to restore the NSR. Other embodiments are also described.

13. Apparatus comprising:
-
a monitor, configured to sense one or more physiological parameters; an electrode device, configured to be coupled to a baroreceptor site of a subject; and a control unit, configured to; detect an episode of non-sinus atrial tachycardia responsively to the one or more sensed physiological parameters, responsively to the detection, wait during a delay period, upon conclusion of the delay period, determine whether the episode has been successfully resolved responsively to the one or more sensed physiological parameters, and responsively to a determination that the episode has not been resolved, restore normal sinus rhythm (NSR) of the subject by; driving the electrode device to apply a stimulation signal to the baroreceptor site, and configuring the stimulation signal to lower a blood pressure of the subject sufficiently to restore the NSR. - View Dependent Claims (14, 15, 16, 17, 18)
