Apple Watch app can detect irregular heartbeats
The Apple Watch can detect atrial fibrillation or irregular heartbeats using its heart sensor and artificial intelligence, according to a University of California, San Francisco study. The 6,158- patient study used the Cardiogram for Apple Watch app and trained a deep neural network to automatically distinguish irregular heartbeats from normal heart rhythms.
The Apple Watch can automatically detect atrial fibrillation (AF) using its built-in heart rate sensor and artificial intelligence, according to a new study.

The research used a deep neural network that was based on photoplethysmographic (PPG) sensors that are frequently found in smart watches. When paired with an artificial intelligence-based algorithm, Apple Watch’s heart rate sensor can detect AF.

There were 6,158 participants in the University of California San Francisco Health eHeart Study who all used Cardiogram for the Apple Watch. The data gathered from the study was used to train a deep neural network to distinguish AF from normal heart rhythm automatically.
