How does it work?
FibriCheck uses photoplethysmography-technology (PPG) to measure your heart rhythm.
When you measure your heart rhythm with FibriCheck, here’s what happens:
- When you hold your finger on your smartphone’s camera, the flashlight illuminates your finger.
- Your skin and underlying tissues absorb some of this light.
- As your blood pulses with each heartbeat, the amount of light changes.
- Your smartphone’s camera monitors these changes in light.
- Our medically certified AI algorithm immediately analyses this.
-
You receive a result and a set of graphs (your measurement report) that can be verified by our team of medical experts and interpreted by your physician.
Why do we use PPG?
-
You only need your smartphone
No additional hardware is required. -
You can measure when and where you want
Heart rhythm disorders come and go, often without symptoms, which is why you can benefit from regular monitoring with FibriCheck. -
Better outcomes through early detection
Early diagnosis and treatment improve the outcome of heart rhythm disorder.
Is it reliable?
FibriCheck is best in class when compared to rivalling devices for heart rhythm monitoring. *
