Fitbit Data to justify cardioversion


Great case report to read if not for the ingenious use of historical heart rate data.

As in the case report described here, the identification that the patient’s atrial fibrillation was present for only a few hours permitted him to undergo cardioversion as opposed to simply receive rate control and then an anticoagulant. Information from the activity tracker could also be used to determine the frequency of tachycardic events in a patient with intermittent atrial fibrillation and aid in determining whether long-term anticoagulation or ablative therapy were required.


put this the camp of “why didn’t i think of that”


does the fibit actually measure heart rate acurately? I feel like I have read the there is very poor accuracy and reliability in these sensors. What could falsely elevate your rate and cause this to be a faulty method
