The wearable combines medical-grade ECG and sleep breathing disturbance detection.
The Fitbit Heart Study is looking to enroll 200,000 to 250,000 device owners, and will support clinical evaluation and regulatory submissions of the company's PPG atrial fibrillation algorithm.
The PPG-based feature automatically measures the wearer's heart rhythm every five minutes, and will be ready for integration with a range of devices later this year.
The new algorithms integrate with Eko's digital stethoscope.

The Belgium-based company's app can render heart rhythm irregularity readings in roughly 60 seconds.
The pair will be targeting patients with asymptomatic or silent atrial fibrillation.
As part of the deal, Oscar Health members who are identified as high risk for diabetes or AFib will be offered confirmatory tests and be referred to an in-network provider.
Among more than 400,000 participants who enrolled in the study, only 0.5 percent ever received an atrial fibrillation alert from the app.
An algorithm trained on a deep neural network was able to perform on par with board certified cardiologist when annotating 12 different types of heart rhythms.
