Abstract: A medical device is configured to set a post-atrial time interval in response to an atrial event and generate an event time signal in response to a ventricular electrical signal crossing an R-wave sensing threshold during the post-atrial time interval. The device accumulates oversensing evidence in response to the event time signal and adjusts a ventricular sensing control parameter based on the accumulated oversensing evidence in some examples.

Abstract: The disclosure describes capturing the cardiac tissue using current steering techniques with a multi-pole cardiac lead implanted near the cardiac tissue. The techniques may include current-controlled sources in an IMD to provide current regulation to the pacing pulses allowing direct stimulation through multiple electrode contacts with known current delivery to the tissue. This current steering technique may use a delivery current source coupled to a delivery electrode and a receiving current source coupled to a receiving electrode to steer the current to the desired tissue to be stimulated. In some examples, different electrode pairs may be paced sequentially or together. In other examples, two or more electrodes may be considered the “delivery electrodes” and two or more electrodes may be considered the “receiving electrodes.” In some examples a current-controlled source in the IMD may be implemented using a source degeneration circuit.

Abstract: Techniques for facilitating improved power management for an implantable device are provided. In one example, an implantable device includes a telemetry circuit and a power management circuit. The telemetry circuit is configured to facilitate a telemetry session between the implantable device and an external device. The power management circuit is configured to connect a power supply to the telemetry circuit via a first current-limiting device based on a determination that the telemetry circuit satisfies a defined criterion. The power management circuit is also configured to connect the telemetry circuit to a second current-limiting device based on a determination that the telemetry circuit is connected to the first current-limiting device for a defined period of time.
