Abstract: Diurnal and nocturnal pacing for an implantable medical device (IMD) that includes a temperature sensor, one or more electrodes, one or more pulse generators and a control circuit is managed. A temperature signal indicative of a core body temperature is sensed at the temperature sensor. The control circuit produces first and second moving composite temperature (MCT) signals based on the temperature signal sensed over first and second periods of time, respectively, wherein the second period of time is longer than the first period of time. A current temperature signal is compared to the first and second MCT signals, and a pacing rate for pacing pulses, generated by the one or more pulse generators and delivered to the one or more electrodes, is controlled based on one or more relations between the current temperature signal, the first MCT signal and the second MCT signal.

Abstract: Implantable medical devices (IMDs) described herein, and methods for use therewith described herein, reduce how often an IMD accepts a false message and/or reduce adverse effects of an IMD accepting a false message. Such IMDs can be leadless pacemakers (LPs), or implantable cardio defibrillators (ICDs), but are not limited thereto. Such embodiments can be used help multiple IMDs (e.g., multiple LPs) implanted within a same patient maintain synchronous operation, such as synchronous multi-chamber pacing.

Abstract: Described herein are implantable medical systems, and methods for use therewith, that provide a temperature based rate response for a patient within which the implantable medical system is implanted. Such a method can include sensing a blood temperature signal indicative of a core body temperature of the patient, and producing a relative temperature signal based on the blood temperature signal. The method can further include producing a moving baseline temperature signal based on the relative temperature signal, producing a proportional response signal based on the relative temperature signal and the moving baseline temperature signal, and producing a sensor indicated rate response signal based on the proportional response signal and a base rate. The sensor indicated rate response signal can also be based on a dip response signal and/or a slope response signal. Additionally, a pacing rate is controlled based on the sensor indicated rate response signal.

Abstract: A cardiac rhythm management system provides an increase in pacing rate as a combination of responses to three characteristics of a relative-temperature signal: a dip, a positive slope, and a positive magnitude. The relative-temperature signal is the difference between a short-term and a long-term temperature average. A dip produces a limited and temporary rate increase having a first proportionality. A positive slope produces a rate increase with a second proportionality. A positive magnitude produces a rate increase with a third proportionality. The dip response seeds the slope response to provide a seamless and immediate rate transition after a dip. The cardiac rhythm management system limits and filters the sum of the rate increases to provide a sensor indicated rate, which is used to stimulate the heart.

Abstract: Techniques for use with an implantable medical device (IMD) reduce how often a first receiver of the IMD wakes up a second receiver thereof to reduce power consumption. A received message and/or a channel over which messages can be received is/are examined, and a value is adjusted based on results thereof. After being adjusted, the value is compared to a first threshold if the IMD is in a normal state, or compared to a second threshold if the IMD is in a noise state. If in the normal state, there is a determination whether to stay in the normal state or switch to the noise state. If in the noise state, there is a determination whether to stay in the noise state or switch to the normal state. At least the second receiver is temporarily put to sleep, if the IMD is maintained in or switched to the noise state.
