Smartwatches Achieve High Accuracy in Detecting Atrial Fibrillation

Smartwatches Redefine Cardiac Health Monitoring with High AFib Detection Accuracy

The evolution of wearable technology has ushered in a new era for preventive healthcare. Among the most promising applications is the use of smartwatches to detect atrial fibrillation (AFib), a cardiac arrhythmia that affects millions globally and carries serious health risks. Recent research published in JACC: Advances confirms that smartwatches have achieved “excellent” diagnostic accuracy in detecting AFib, with pooled sensitivity and specificity exceeding 94% and 96%, respectively. This breakthrough highlights the transformative potential of wearable devices in early diagnosis and continuous heart monitoring. AFib, characterized by irregular heartbeats, impacts approximately 5% of the U.S. adult population, equating to around … Read more
