Hazlinney........years ago BP was taken lying down after a rest, even at the Drs surgery. But the argument was that you spent the most of your life, standing up or sitting down and a BP after rest and or lying down was not a true representatative of your cardiovascular state.
I agreed.
So now at home if one takes one's BP 2 or 3 times a day, sitting, then that gives a true representative of one's BP i.e whether treatment is necessarry or not.
