Wouldn't this help with pre-stroke detection? The article mentioned that 1 in 4 strokes are caused by AFib. I would imagine this would be helpful for in-patient Neuro-ICU and stroke hospitalists. On the patient side, shouldn't something like this - assuming the monitoring is in real-time - provide a preventative/detection benefits for patients with a high-risk for stroke?
Even before that - putting in on an Apple Watch potentially enables screening from a public health perspective. I'd rather prevent the stroke rather than regretfully putting the patient on coumadin after they've been paralyzed...
