“The role that technology plays in allowing patients to capture meaningful data about what’s happening with their heart, right when it’s happening, like the functionality of an on-demand ECG, could be significant in new clinical care models and shared decision making between people and their healthcare providers,” said Nancy Brown, CEO of the American Heart Association, the world’s leading voluntary organization focused on heart and brain health. “At the American Heart Association, we are committed to educating and empowering people to be proactive in all areas of their heart health and general well-being.”
“The idea that wearables can be used by both patients and their health care providers to manage and improve heart health holds promise and should also be approached with caution to ensure information and data are used responsibly and in concert with other evidence-based tools and guidelines,” said C. Michael Valentine, MD, FACC, president of the American College of Cardiology. “The ACC, through its focus on innovation, is committed to exploring ways that new technologies can optimize patient care and outcomes.”
The ECG app’s ability to accurately classify an ECG recording into AFib and sinus rhythm was validated in a clinical trial of around 600 participants. Rhythm classification from a gold standard 12-lead ECG by a cardiologist was compared to the rhythm classification of a simultaneously collected ECG from the ECG app. The study found the ECG app on Apple Watch demonstrated 98.3 percent sensitivity in classifying AFib and 99.6 percent specificity in classifying sinus rhythm in classifiable recordings. In the study, 87.8 percent of recordings could be classified by the ECG app.
