I use my Apple watch for monitoring. It alerted me in both episodes. One lasted 2 months and the other 3 weeks. These are not very short periods like what you are describing. Also, if you are taking meds that make your blood pressure normal, are you scored as hypertensive in all these “models” that determine whether you should be prescribed Xarelto? I have a problem with a model that gives you -0- if you are 64 and a full 1 if you are 65.
