Abstract: A medical device system includes a memory; and processing circuitry in communication with the memory. The processing circuitry is configured to receive parametric data for a plurality of parameters of a patient, determine, based on the parametric data, an atrial fibrillation (AF) burden of the patient over a period of time, wherein the AF burden of the patient over the period of time includes a pattern of increased AF burden; output, for display by a user device, a request to identify whether the patient engaged in each patient behavior of a set of patient behaviors during the period of time; and determine, based on receiving a response indicating that the patient engaged in one or more patient behaviors of the set of patient behaviors, a suggestion to change at least a subset of the one or more patient behaviors to attenuate the pattern of increased AF burden.
