AFib

Cardio Intelligence is now testing its latest AI for detecting paroxysmal atrial fibrillation. 

It is offering free two-week access to the FibriCheck feature on its app for the first 100,000 users.   

New research finds using a smartphone app more than doubles detection and treatment rates in older people

The Rhythm Evaluation for AntiCoagulaTion (REACT-AF) trial will study a "pill-in-pocket" method of stroke prevention for patients with atrial fibrillation. Some participants will monitor for AFib using an Apple Watch and take blood thinners as needed, instead of using the drug continuously.

The latest clearance is for an algorithm that characterizes how much atrial fibrillation a patient is experiencing over time.

The tech giant also announced a new atrial fibrillation history feature and sleep stage tracking.

The new algorithm is able to assess a user's heart rhythm when they are asleep or still. 

The latest feature can now be combined with Samsung's cuffless blood pressure monitoring feature, which got approval in South Korea a few weeks ago. 

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.
