High frequency atrial burst pacing for improved ventricular rate control during atrial arrhythmias
First Claim
1. A medical device for delivering cardiac stimulation, comprising:
- a first electrode, positioned within a first chamber of a heart, sensing cardiac signals associated with the first chamber and capable of delivering stimulation to the first chamber;
a second electrode, positioned within a second chamber of the heart, sensing cardiac signals associated with the second chamber and capable of delivering stimulation to the second chamber;
a processing unit processing the sensed signals and controlling the stimulation delivery via the first electrode and the second electrode, the processing unit determining whether a predetermined rhythm is detected in the first chamber and delivering high-frequency burst pacing to the first chamber in response to a predetermined rate being sensed in the second chamber during the predetermined; and
a patient signaling device generating a patient-generated signal, wherein the processing unit detects the patient-generated signal and delivers high-frequency burst pacing to the second chamber of the heart in response to the patient-generated signal.
