Ive been doing side by side BP tests with the arm vs wrist machines. Sys is normally 10-15 higher and dis is 5-10 higher on the arm vs the wrist. Seems like quite a large discrepancy.
My arms are just about 17" and the arm monitor I bought is made for that size. It does seem to get quite tight when it measures, though. My doc also uses the "large" cuff and my BP has always been high when visiting the doc. He's having me keep a log for a month, then he's going to test against his manual method when I visit him next. (I'm bringing both the arm and wrist ones)
Anyone else have experience with either arm vs wrist BP monitors, or having issues of higher readings on the arm because of muscle mass? I have to believe it plays PART of a role.. but havent really found much info. I find it hard to believe that some of my friends who lay around smoking wacky tabacy, drinking every day and eating pizza have no BP issues, but myself who lifts 3x a week and runs 2-3x a week and eats "better than average" has BP issues.
I'm sure I'm not the only one who's run into this.
