If you remember your high school biology, the atriums are the top two chambers of the heart, while the ventricles are the bigger, bottom two. Atrial fibrillation is a problem with the squeezing motion of the atriums. “It’s almost tremulous and shaking—it’s not a cohesive unit that squeezes together,” explains Suzanne Steinbaum, a cardiologist who focuses on women’s heart health at The Mount Sinai Hospital. “And so what happens is, as it circulates, blood can pool in that atrium, and when blood pools, it clots.” That clot could cause a stroke, so an ECG test that can help screen for atrial fibrillation has an obvious advantage.

And there lies the life-saving potential of this gadget, and other home ECG tests. “If we can detect atrial fibrillation—which is a major cause of stroke in the US—before patients end up with a stroke, it could be very, very helpful,” says Adam Skolnick, a cardiologist with NYU Langone Health. A device that someone frequently has on them and screens for that is useful, because the condition isn’t always something a patient feels.
