The article in the influential medical journal is a response to a recent study in the same publication on the utility of Fitbit watches for detecting AF. More scientific evaluation is needed to develop and validate consensus recommendations to ensure that benefits will outweigh risks for consumers who use smartwatches in screening themselves for AF, says Gregory Marcus, MD, MAS, a UCSF professor of medicine with the Division of Cardiology, in an opinion piece in Circulation. That’s the conclusion of a UC San Francisco cardiologist who specializes in arrhythmias and was among the first to explore the potential of smartwatches to alert wearers about possible atrial fibrillation (AF), a serious condition that can sometimes lead to deadly strokes.

Company claims are leaping ahead of medical science in promoting the use of smartwatches to screen for heart rhythm disorders.
