    摘要： 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.

    摘要： 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.
