System and method of cardiac pacing during sleep apnea
First Claim
Patent Images
1. A method for treating a patient experiencing sleep apnea, the method comprising:
- detecting an episode of sleep apnea;
determining one or more parameters for a cardiac pacing pulse, wherein the one or more parameters are selected to create a hemodynamic imbalance within a patient'"'"'s cardiovascular system; and
delivering at least one of the cardiac pacing pulses to the patient'"'"'s heart.

Abstract
An exemplary method for treating sleep apnea is described that includes determining parameters for a cardiac pacing pulse based, at least in part, on information characteristic of sleep apnea, wherein the cardiac pacing pulse aims to create a hemodynamic imbalance. An exemplary implantable cardiac device is programmable to perform such an exemplary method. Other exemplary methods, devices, and/or media are also disclosed.

12. An implantable cardiac stimulation system comprising:
-
a pulse generator that generates cardiac pacing pulses for delivery to a patient'"'"'s heart; a sleep apnea detector that is operative to detect an episode of sleep apnea; and a sleep apnea therapy module that is responsive to the episode of sleep apnea to control the pulse generator to generate one or more non-physiologic pacing pulses, wherein the one or more non-physiologic pacing pulses are operative to cause a hemodynamic imbalance within the patient. - View Dependent Claims (13, 14, 15)

16. The system as recited in 12, wherein the cardiac pacing pulse creates an abnormal cardiac electrical rhythm and the sleep apnea therapy module receives feedback from the sleep apnea detector to vary the morphology of the abnormal cardiac electrical rhythm.

17. A method for treating a patient experiencing sleep apnea, the method comprising:
-
detecting an episode of sleep apnea; and in response to the episode of sleep apnea, delivering a ventricular stimulation pulse at an atrioventricular delay of less than about 25 milliseconds following an atrial event.

18. A method for treating a patient experiencing sleep apnea, the method comprising:
-
detecting an episode of sleep apnea in a patient; and applying at least one cardiac pacing pulse to the patient'"'"'s heart to create a hemodynamic imbalance within the patient'"'"'s cardiovascular system in response to the detection of an episode of sleep apena.

-
19. An implantable cardiac stimulation system comprising:
-
means for detecting an episode of sleep apnea in a patient; and means for applying at least one cardiac pacing pulse to the patient'"'"'s heart to create a hemodynamic imbalance within the patient'"'"'s cardiovascular system in response to the detection of an episode of sleep apena. - View Dependent Claims (20, 21, 22)
