DUAL CHAMBER TIMING FOR LEADLESS PACEMAKERS USING INFREQUENT ATRIAL SIGNALS AND VENTRICULAR CONTRACTIONS
First Claim
1. A method for adjusting a pacing rate in a dual-chamber, leadless pacemaker system implanted in a heart, the method comprising:
- determining, with a leadless atrial pacemaker implanted in an atrium of the heart, that an intrinsic atrial contraction rate of the atrium is faster than a ventricular contraction rate;
transmitting a first signal from the atrial pacemaker to a leadless ventricular pacemaker implanted in a ventricle of the heart to increase a ventricular pacing rate of the ventricular pacemaker;
receiving the transmitted first signal with the ventricular pacemaker; and
increasing the ventricular pacing rate, based on the received first signal.

Abstract
A method for adjusting a pacing rate in a dual-chamber, leadless pacemaker implanted in a heart may involve determining, with a leadless atrial pacemaker implanted in an atrium of the heart, that an intrinsic atrial contraction rate of the atrium is faster than a ventricular contraction rate, transmitting a first signal from the atrial pacemaker to a leadless ventricular pacemaker implanted in a ventricle of the heart to increase a ventricular pacing rate of the ventricular pacemaker, receiving the transmitted first signal with the ventricular pacemaker, and increasing the ventricular pacing rate, based on the received first signal.

17. An implantable, dual-chamber, leadless pacemaker system, comprising:
-
an atrial leadless pacemaker, comprising; a sensing module configured to sense signals indicative of ventricular contractions; a processing module configured to determine whether an intrinsic atrial contraction rate is greater than a ventricular contraction rate; and a communication module configured to transmit a signal to a ventricular leadless pacemaker to increase a ventricular pacing rate in response to instructions from the processing module to increase the ventricular pacing rate; and a ventricular leadless pacemaker, comprising; a sensing module configured to receive the transmitted signal from the atrial pacemaker; and a processing module configured to increase the ventricular pacing rate according to the received signal, to determine when no signal has been received from the atrial pacemaker for a predetermined amount of time, and to decrease the ventricular pacing rate when no signal has been received from the atrial pacemaker for the predetermined amount of time. - View Dependent Claims (18, 19, 20, 21, 22, 23)
