Abstract

Systems and methods are disclosed to determine and record one or more key metrics of atrial fibrillation for a patient, including determining indications of atrial fibrillation of the patient in respective detection windows of a day using received physiologic information, recording first physiologic information of the patient at a first sampling frequency for the determined indications of atrial fibrillation of the patient up to and not exceeding a first threshold of the medical device system for transmission to a remote device, and determining and recording one or more key metrics of atrial fibrillation for the determined indications of atrial fibrillation of the patient at a second sampling frequency lower than the first sampling frequency without regard to the first threshold.

A medical device system, comprising:

a signal receiver circuit configured to receive physiologic information of a patient;
and
an assessment circuit configured to:
determine indications of atrial fibrillation of the patient in respective detection windows of a day using the received physiologic information;
record first physiologic information of the patient at a first sampling frequency for the determined indications of atrial fibrillation of the patient up to and not exceeding a first threshold of the medical device system for transmission to a remote device;
and
determine and record one or more key metrics of atrial fibrillation for the determined indications of atrial fibrillation of the patient at a second sampling frequency lower than the first sampling frequency without regard to the first threshold.
