 And how do you monitor yourself? You can have a Fitbit. You can have these recent smartwatches that can tell you if you have AFib. You can just do your blood pressure monitoring at home because people forget when you do a blood pressure, you can also see what your heart rate is doing. So when we're talking about AFib, patients normally come to me and they say, oh, my blood pressure was this. My upper number was this. My lower number was this. And I always ask them, what was your pulse?
