Atrial Fibrillation (AF) is the most common arrhythmia that affects about 2% of the population. The prevalence of AF increases with age, from 0.5% at 40–50 years, to 5–15% at 80 years. AF is associated with increased rates of death, stroke, heart failure and hospitalizations as well as degraded quality of life, reduced exercise capacity, and left ventricular dysfunction.
AF can be paroxysmal, meaning that AF events can occur episodically and self-terminate; in such cases the clinical diagnosis is performed by Holter recordings usually for 24h or 7 days. However, because of the time irregularity of this pathology, the monitoring period could be insufficient to detect AF. The main risks of undiagnosed AF events are associated to cardioembolic stroke and AF-related complications whose management would imply higher costs for health care system.
The project aim at the development of a contactless fully automated system for screening of AF patient in different environments. The system consists of a videoPPG system, i.e. camera that detects variations of light intensity reflected by a region of subject’s face, positioned at a variable distance. From video recordings, the blood volume pulse (BVP) of peripheral arteries is extracted and processed to detect AF.
