Belgium-based app maker FibriCheck has announced a new version of its smartwatch app that is capable of automatically monitoring the users’ heart rhythms while they sleep.

The app can be integrated into any smartwatch and can detect episodes of intermittent and silent atrial fibrillation, in which symptoms are either irregular or non-existent, making it difficult to diagnose.

Atrial fibrillation is responsible for about 25 per cent of strokes, the majority of which are preventable if diagnosed and treated in a timely manner.

The app automatically monitors the wearer’s heart rhythm ever five minutes and then provides a nightly overview and any alerts. These can also be forwarded to doctors for follow-up and treatment.

FibriCheck CEO Lars Grieten said: “Our goal is to make it as easy as possible for people to know if they have a heart rhythm irregularity, to prevent AF strokes from happening.”

“The FibriCheck heart rhythm app is a device-agnostic medical software application that can easily be integrated into any phone or wearable product that uses PPG (photoplethysmography) sensors.”

“For smartphone, smartwatch and consumer technology companies, this opens up new possibilities to expand product offerings and provide consumers with innovative ways to manage their health and health-related conditions, including better heart health.”

The company has said that the revamped app is towards the end of user testing and will be available to smartwatch manufacturers in the second half of this year.
