So wife bougth me a home BP unit and the app showed systolic like 170 and dia..whatever... 80.

Can this be rigth?. Im at cycle end and precycle BP was 125/80.
Tried numerous times and the readings were 185-160 over 75-90.

But can aas cause that isolated systolic hypertension?
Before i think i remember both used tobe elevated.
Ive red 170/80 is real real bad news.

I have big arms and that has been a problem for accurate readings before.
