I have been using a blood pressure monitor to see what happens when I go from lying to standing and found that as well as my heart rate increasing my blood pressure goes up rather than down/ staying the same.
eg last night I was lying down: heart rate 79 BP 114/73
when I stood up it became: heart rate 115 (+36) BP 132/77
I'm not sure if that is of any siginficance. I have also done it from walking upstairs mainly to find my heart rate for that activity and, for example, first measurement hr was 143 and BP systolic was 123 then few mins later heart rate had come down to 117 but systolic was now 144. diastolic usually stays around late 60s and 70s but systolic seems to vary a lot more.
I haven't seen any mention of increased systolic in anything I have read about OI.
