People who have a heart arrhythmia called atrial fibrillation now have a less-invasive way to track the condition. All it takes is a smart phone and an app called Cardio Rhythm.
The application analyzes a person's facial skin color via a smart phone camera. In testing, it was accurate in 92 percent of the readings — including a select group that had been diagnosed with atrial fibrillation previously with an ECG scan.
Researchers at the Chinese University in Hong Kong created the app.
