Abstract: A medical device system including a pacemaker implantable in an atrial chamber of a patient's heart is configured to sense near field atrial events from a cardiac signal received by a sensing module of the pacemaker and to sense far field ventricular events. The pacemaker is configured to establish an atrial lower rate interval to control a rate of delivery of atrial pacing pulses, determine a rate of the far field ventricular events sensed by the sensing module, determine an atrial event rate, compare the rate of the sensed far field ventricular events to the atrial event rate, and adjust the atrial lower rate interval in response to the comparison.

Abstract: A medical device system including an pacemaker implantable in a chamber of a patient's heart is configured to sense near field events from a cardiac electrical signal, establish a lower rate interval to control a rate of delivery of pacing pulses and schedule a first pacing pulse by starting a pacing escape interval set equal to the lower rate interval. The pacemaker withholds the scheduled pacing pulse in response to sensing a near-field event during the pacing escape interval and schedules a next pacing pulse to be delivered at the lower rate interval from a time that the pacing escape interval is scheduled to expire.

Abstract: A medical device and method conserve electrical power used in monitoring cardiac arrhythmias. The device includes a sensing circuit configured to sense a cardiac signal, a power source and a control circuit having a processor powered by the power source. The control circuit is configured to operate in a normal state by waking up the processor to analyze the cardiac electrical signal for determining a state of an arrhythmia. The control circuit switches from the normal state to a power saving state that includes waking up the processor at a lower rate than during the normal state.

Abstract: Systems, apparatus, methods and computer-readable storage media facilitating management of operation of an implantable medical device (“IMD”) using a number of communication modes are provided. An IMD is configured to operate in a disabled mode wherein radio frequency (RF) telemetry communication is disabled, or operate in a first advertising mode using the RF telemetry communication. The IMD receives a clinician session request from a clinician device via an induction telemetry protocol while operating in the disabled mode or the first advertising mode, and transitions to operating from the disabled mode or the first advertising mode to operating in a second advertising mode based on receiving the clinician session request. From the second advertising mode, the IMD can establish a clinician telemetry session with the clinician device using the RF telemetry communication and a unique security mechanism facilitated by an identifier for the clinician device included in the clinician session request.

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: The present invention provides a technique for verifying pacing capture of a ventricular chamber, particularly to ensure desired delivery of a ventricular pacing regime (e.g., “CRT”). The invention also provides ventricular capture management by delivering a single ventricular pacing stimulus and checking inter-ventricular conduction during a temporal window to determine if the stimulus captured. If a loss-of-capture LOC) signal results from the capture management testing, then the applied pacing pulses are modified and the conduction test repeated. If LOC, an alert message can issue. Other aspects include: use of a trend of A-RV/LV and LV-RV timing intervals to monitor changes in the patient's heart conduction properties; bi-ventricular verification test and search—while still pacing BiV by detecting latent sense; single-V pacing threshold search, use of timing of sense in other V chamber to establish capture and LOC windows; (iv) use of a premature V pace rather than short AV interval if VV cannot be discriminated from AV; (v) option to run a threshold search only if the Bi-ventricular verification test fails.
Abstract translation: 本发明提供了一种用于验证心室的起搏捕获的技术，特别是确保心室起搏方案（例如CRT）的期望的递送。 本发明还通过递送单个心室起搏刺激并且在时间窗口期间检查心室间传导来确定是否捕获刺激来提供心室捕获管理。 如果捕获管理测试产生捕获失控LOC信号，则应用起搏脉冲进行修改，并重复传导测试。 如果LOC，可以发出警报消息。 其他方面包括：使用A-RV / LV和LV-RV时间间隔的趋势来监测患者心脏传导性质的变化; 通过检测潜在感觉仍然起搏BiV，双心室验证测试和搜索; 单V起搏阈值搜索，使用其他V腔中的定时定时来建立捕获和LOC窗口; （iv）如果VV不能与AV区别，则使用过早的V步速而不是短AV间隔; （v）仅当双心体验证测试失败时才能运行阈值搜索的选项。
