    Abstract: Systems and methods for managing machine-generated alerts of a medical event such as worsening heart failure (WHF) are described. A patient management system includes a patient database of information about a correspondence between a plurality of alert thresholds (ATHs) and corresponding clinical outcome indicators (COIs) for a plurality of patients. A control circuit can query the patient database for a matching patient that meets specific query criteria compared to a target patient, retrieve an ATH-COI correspondence associated with the matching patient, and determine the alert threshold using a user input of a COI and the retrieved ATH-COI correspondence. A medical event detector detects the medical event using physiological signals sensed from the target patient and the determined alert threshold.

    Abstract: An interrogation system for a medical device includes a memory storing a diagnostic algorithm, a processor configured to run the diagnostic algorithm, and a communication module configured to facilitate data transfer between the interrogation system and the medical device. The diagnostic algorithm is configured to reach a diagnostic conclusion based on data from the medical device. The diagnostic algorithm is configured to iteratively interrogate the medical device for the data from the medical device until the diagnostic algorithm reaches the diagnostic conclusion, each iterative interrogation requesting additional data as compared to prior iterations. The communication module is configured to receive the additional data from the medical device in response to each iterative interrogation. The diagnostic algorithm is further configured to store an indication of the diagnostic conclusion within the memory.

    Abstract: System and methods for energy adaptive communications between medical devices are disclosed. In one example, a medical device includes a communication module configured to deliver a plurality of pulses to tissue of a patient, where each pulse has an amount of energy. A control module operatively coupled to the communication module, may be configured to, for each delivered pulse, determine whether the delivered pulse produces an unwanted stimulation of the patient and to change the amount of energy of the plurality of pulses over time so as to identify an amount of energy that corresponds to an unwanted stimulation threshold for the pulses. The control module may then set a maximum energy value for communication pulses that is below the unwanted stimulation threshold, and may deliver communication pulses below the maximum energy value during communication with another medical device.
