Abstract: A system and method for detecting and verifying bradycardia/asystole episodes includes sensing an electrogram (EGM) signal. The EGM signal is compared to a primary threshold to sense events in the EGM signal, and at least one of a bradycardia or an asystole is detected based on the comparison. In response to detecting at least one of a bradycardia or an asystole, the EGM signal is compared to a secondary threshold to sense events under-sensed by the primary threshold. The validity of the bradycardia or the asystole is determined based on the detected under-sensed events.

Abstract: This disclosure describes systems, devices and techniques for improving the longevity of battery life in a device. An example first device includes communication circuitry configured to communicate with a second device and processing circuitry configured to determine an expected amount of data to be transmitted by the second device to the first device. The processing circuitry is configured to determine that the expected amount of data to be transmitted by the second device to the first device is greater than or equal to a predetermined data threshold and based on the expected amount of data to be transmitted being greater than or equal to the predetermined data threshold, determine that a predetermined restriction is met. The processing circuitry is configured to, based on the predetermined restriction being met, control the communication circuitry to transmit an instruction to the second device.
