Hi, Vince, I have found that Harvard Health is about as reliable as Harvard politics... both corrupt... both STINKO... JMHO!
I had a Doc appt just a few days ago... 160/80. This has happened a few times before, my normal Doc visits come in at 120/80 or better, so it is not any stress over seeing a Doc... I am not uptight about those visits... here is an alternative take, as my UroDoc told me... if you get walked back to the room you will see the Doc in, by his assistant... and she takes your BP immediately... you have a great chance of coming in high... while if you have a chance to sit still for awhile before taking... chances are, your result will be far more accurate. Ditto if you come in high in the first scenario, then ask your Doc to take your BP again at end of appointment... and I have done this... it comes in much lower. You are not supposed to take BP after even walking around for awhile... for accurate results, you need to be sitting down quietly for at least a few minutes. Test it out at home if you have a monitor!
