Rugbyears I wouldn't worry too much.
I tried one of those home test jobbies and I get consistently inconsistent readings. The lowest I remember was about 80/30. The 190/110 had me worried for a bit mind you so it went up to 220/120, all within an hour of each other! They do appear to be horribly inaccurate and I wouldn't waste your time but maybe I had a cheap crappy one.
Every medical I've had my BP has been between 120/60 and 130/70. Resting heart rate of about 80.
I'm 6'2", 15st. Smoke a bit, drink even less and exercise even less than that.
