CardioSignal application can save your life!


Atrial fibrillation is the most common cardiac disorder and even 25% of the population may have atrial fibrillation during their life. Without a treatment it can increase your risk of stroke, heart failure and other heart-related complications.

Atrial fibrillation can also be symptomless and therefore difficult to detect. With CardioSignal smartphone application you can easily measure your heart and detect atrial fibrillation with 95% accuracy. 

Simply, lay down, relax, press start button and place the smartphone on your chest. Wait for 1 minute and the result will be ready in few seconds after the measurement.

Precordior is developing the next generation of cardiac monitoring solutions. Our patented and patent-pending methods non-invasively measure the motion of the heart. In practice, CardioSignal mobile application uses accelerometer and gyroscope to measure the motion of the precordium, the chest area above the heart. With this technology, we can produce a seismocardiogram indicating 3D linear motion, and a gyrocardiogram indicating 3D rotational motion along three axes. By analyzing this detailed data our algorithms can determine incredibly reliably for example whether the subject is suffering from atrial fibrillation.
