Abstract: Techniques are disclosed for adjusting event detection parameters used for sensing mechanical motion data of a heart of a patient for use in cardiac pacing therapy. For example, processing circuitry receives, from a user, an input specifying one or more event detection parameters defining mechanical motion sensing of a heart of a patient by one or more motion sensors of an implantable medical device (IMD). The processing circuitry controls the IMD to perform mechanical motion sensing of the heart of the patient in accordance with the one or more event detection parameters. The processing circuitry obtains mechanical motion data of the heart of the patient sensed in accordance with the one or more event detection parameters. The processing circuitry controls the IMD to deliver cardiac pacing therapy based on the mechanical motion data of the heart of the patient sensed in accordance with the one or more event detection parameters.

Abstract: Systems, devices, and techniques for establishing communication between two medical devices are described. In one example, an implantable medical device comprises communication circuitry, therapy delivery circuitry, and processing circuitry configured to initiate a communication window during which the implantable second medical device is capable of receiving the information related to a cardiac event detected by a first medical device, the communication window being one of a plurality of communication windows defined by a communication schedule that corresponds to a transmission schedule in which the first medical device is configured to transmit the information, control the communication circuitry to receive, from the first medical device, the information related to the cardiac event that is indicative of a timing of the cardiac event with respect to a timing of the communication window, schedule and control delivery of a therapy according to the information related to the cardiac event.

Abstract: A pacemaker is configured to operate in an atrial synchronous ventricular pacing mode and, after expiration of a conduction check time interval, switch to an asynchronous ventricular pacing mode that includes setting a ventricular pacing interval to a base pacing rate interval. The pacemaker is further configured to determine when atrioventricular block detection criteria are satisfied during the asynchronous ventricular pacing mode and, responsive to the atrioventricular block detection criteria being satisfied, switch back to the atrial synchronous ventricular pacing mode.

Abstract: In an example, an implantable medical device (IMD) includes a hold capacitor configured to deliver an electrical therapy pulse, and charge pump circuitry configured to transfer energy from the battery to the hold capacitor. In this example, the charge pump circuitry comprises a plurality of capacitors, and switching circuitry configured to put the charge pump circuitry into a K-factor mode selected from a group of K-factor modes by opening and closing a combination of switches connected to the plurality of capacitors.
