Abstract: An implantable medical device system receives a cardiac electrical signal produced by a patient's heart and comprising atrial P-waves and delivers a His bundle pacing pulse to the patient's heart via a His pacing electrode vector. The system determines a timing of a sensed atrial P-wave relative to the His bundle pacing pulse and determines a type of capture of the His bundle pacing pulse in response to the determined timing of the atrial P-wave.

Abstract: Techniques for facilitating telemetry between a medical device and an external device are provided. In one example, a medical device includes a classification component and a communication component. The classification component is configured to determine a classification for data generated by the medical device. The classification component is also configured to determine an urgency level for an advertising data packet based on the classification for the data. The communication component is also configured to broadcast the advertising data packet for the medical device at a defined beaconing rate based on the urgency level for the advertising data packet.

Abstract: An IMD system receives a near field His bundle electrical signal produced by a patient's heart via a first sensing electrode vector and a far field cardiac electrical signal via a second sensing electrode vector different than the first sensing electrode vector. The IMD system generates His bundle pacing pulses delivered to the patient's heart via a His pacing electrode vector and determines a type of cardiac capture evoked by a His bundle pacing pulse.

Abstract: Techniques for determining an attachment stability of leadless pacing device (LPD) implanted within a patient are described. For example, the LPD may detect one or more stability metrics from one or more electrodes of the LPD and/or an activity sensor within the LPD. Based on one or more of these stability metrics, e.g., a mechanical motion of the LPD, a stability module within the LPD may determine the attachment stability of the LPD within the patient. If the attachment stability is insufficient to provide efficacious therapy or indicates at least partial dislodgement of the LPD from tissue, the LPD may wirelessly transmit stability information to an external device. In some examples, the LPD may be implanted within a chamber of the heart.

Abstract translation: 描述了用于确定植入在患者体内的无引脚起搏装置（LPD）的附着稳定性的技术。 例如，LPD可以从LPD的一个或多个电极和/或LPD内的活动传感器检测一个或多个稳定性度量。 基于这些稳定性度量中的一个或多个，例如LPD的机械运动，LPD内的稳定性模块可以确定患者体内LPD的附着稳定性。 如果连接稳定性不足以提供有效的治疗或指示LPD至少部分从组织移走，则LPD可以将稳定性信息无线传输到外部设备。 在一些实例中，LPD可以植入心脏的腔室内。
