HOW DOES THE APP WORK?

To detect the heart rate and the heart rhythms, simply place the fingertip at the smart phone’s camera.  The tiny light sensors that make up the camera are sensitive enough to pick up small colour changes on the surface of the skin that synchronise with your pulse.


This is caused by blood flow changes from your heart pumping and the advanced software algorithm to detect the blood flow micro changes, with beat-to-beat accuracy.

The APP uses the Preview Call Back mechanism to grab the latest image from the preview frame. It then processes the stored images data and retrieves all red pixels values (refer to illustration).

The variable pixels are illuminated by the camera light and measured by the megapixel photo detecting lens as it passes through the pulsating capillary tissue beneath the surface of the finger. Measurements are tracked for each of the flow signals.

AF DETECT

Atrial fibrillation (AF) is a medical term for irregular heartbeat. A type of arrhythmia or heartbeat irregularity, AF is the most common heart rhythm condition typically found in one in four adults over the age of 40 developing the condition in their lifetime.


It is characterised by irregular heartbeat, which has no predictable pattern. People with AF are more likely to develop blood clots in the heart, which can be “thrown off” during the pumping of the heart. This can cause a stroke (Thrombo-embolic) in the vessels of the brain when the blood clot travels out of the heart.

The presence of AF increases the risk of stroke by five-fold. Globally, one in ten patients who are brought to the emergency department due to atrial fibrillation will die within one year.
