Rithmi is a non-invasive and widely used wearable device, responsible for recording data and detecting arrhythmias in real time.
The technology employed uses a recording system based on photoplethysmography (PPG). The PPG sensor measures the intensity of light reflected from the surface of the skin and the red blood cells underneath to determine the volume of blood in the respective area at any given moment. With this data we obtain a pulse wave of the heart and can determine when each heartbeat occurs.
This, together with the development of a proprietary algorithm capable of detecting possible arrhythmias in the heart, allows the monitoring and tracking of the user’s health in their daily activity.
