Abstract: An intracardiac ventricular pacemaker is configured to detect an atrial mechanical event from a motion sensor signal received by an atrial event detector circuit of the pacemaker. The motion sensor signal is responsive the motion of blood flowing in the ventricle. A pacing pulse is scheduled at an expiration of a pacing interval set by a pace timing circuit in response to detecting the atrial mechanical event. An atrial-synchronized ventricular pacing pulse is delivered upon expiration of the pacing interval.

Abstract: An implantable medical device includes an activity sensor, a pulse generator, and a control module. The control module is configured to determine activity metrics from the activity signal and determine an activity metric value at a predetermined percentile of the activity metrics. The control module sets a lower pacing rate set point based on the activity metric value at the predetermined percentile.

Abstract: In some examples, a leadless pacing device (hereinafter, “LPD”) is configured for implantation in a ventricle of a heart of a patient, and is configured to switch between an atrio-ventricular synchronous pacing mode and an asynchronous ventricular pacing mode in response to detection of one or more sensing events, which may be, for example, undersensing events. In some examples, an LPD is configured to switch from a sensing without pacing mode to an atrio-ventricular synchronous pacing mode in response to determining, for a threshold number of cardiac cycles, a ventricular depolarization was not detected within a ventricular event detection window that begins at an atrial activation event.

Abstract: An intracardiac ventricular pacemaker is configured to operate in in a selected one of an atrial-tracking ventricular pacing mode and a non-atrial tracking ventricular pacing mode. A control circuit of the pacemaker determines at least one motion signal metric from the motion signal, compares the at least one motion signal metric to pacing mode switching criteria; and responsive to the pacing mode switching criteria being satisfied, switches from the selected one of the non-atrial tracking pacing mode and the atrial tracking pacing mode to the other one of the non-atrial tracking pacing mode and the atrial tracking pacing mode for controlling ventricular pacing pulses delivered by the pacemaker.

Abstract: An implantable rate responsive pacemaker includes a sensor module configured to produce an activity signal correlated to a metabolic demand of a patient and a posture signal correlated to patient posture. The pacemaker further includes a pulse generator configured to generate and deliver pacing pulses to a patient's heart via a pair of electrodes coupled to the pacemaker. A control module is coupled to the pulse generator and the sensor module and is configured to determine a sensor indicated pacing rate from the activity signal, compare the posture signal to verification criteria for confirming an exercising posture of the patient, and withhold an adjustment of a pacing rate to the sensor indicated pacing rate responsive to the verification criteria not being met.

Abstract: A method and apparatus for determining estimated remaining longevity for an implantable stimulator. The device employs pre-calculated numbers of days for various combinations conditions of device usage parameters to determine remaining device longevity based upon identified actual conditions of device usage and employs the determined longevity to change longevity indicator states in the device. While between longevity state changes, the device the identified conditions of device usage and adjusts the determined longevity if the conditions of use change significantly. The indicator states may correspond to one or more of Recommended Replacement Time (RRT), Elective Replacement Indicator (ERI) or End of Service (EOS).

Abstract: An intracardiac pacemaker is configured to filter a raw cardiac electrical signal received by the pacemaker to produce a filtered cardiac electrical signal, analyzes the filtered cardiac electrical signal to establish cardiac event sensing criteria that discriminate P-waves from T-waves and R-waves all present in the raw cardiac electrical signal, and sense the P-waves from the filtered cardiac electrical signal when the established cardiac event sensing criteria are met. Sensed P-waves may be used for controlling atrial-synchronized ventricular pacing delivered by the pacemaker.

Abstract: An intracardiac pacemaker is configured to receive a cardiac electrical signal developed across a pair of electrodes coupled to the pacemaker and detect a crossing of a first sensing threshold of the cardiac electrical signal. A pacing escape interval timer is set to a first pacing escape interval in response to the cardiac electrical signal crossing the first sensing threshold. The pacing escape interval timer is adjusted if the cardiac electrical signal crosses a second sensing threshold during a time limit.
