iPhone camera application may detect atrial fibrillation

November 14, 2016

NEW ORLEANS, Nov. 14, 2016 -- A smartphone application made it possible to use the iPhone camera to detect atrial fibrillation via facial signals and without physical contact, according to a preliminary study presented at the American Heart Association's Scientific Sessions 2016.

The technology, called Cardiio Rhythm, detects subtle beat-to-beat variations in facial skin color, which reflect a person's heart rate fluctuation. They tested the app on 85 hospitalized patients, comparing the app to recordings on a 12-lead electrocardiogram (ECG).

The 12-lead ECG detected atrial fibrillation in 25 of the 85 patients. The smartphone application correctly identified more than 92 percent of cases with atrial fibrillation and nearly 95 percent of cases without atrial fibrillation.

The convenience of a contact-free approach makes the technology attractive for large-scale community atrial fibrillation screenings, researchers said.

Anticoagulant benefits for atrial fibrillation decrease with age
The net clinical benefit of anticoagulants for atrial fibrillation (AF) -- one of the most important causes of irregular heartbeats and a leading cause of stroke -- decreases with age, as the risk of death from other factors diminishes their benefit in older patients, according to a study led by researchers at UC San Francisco.

Research improves understanding of mechanism of atrial fibrillation
Mouse model studies show that noncoding DNA regions linked to atrial fibrillation risk can display long-range regulatory functions directed at Pitx2 gene and in this way predispose to the condition.
