Okay, so I've always heard that heart rate and blood pressure are linked, to the degree that significantly raising or lowering the former will nudge the latter in the same direction. (In a well publicized study, nurses observed that patients visiting their doctor's office tested lower after sitting and resting for a while than those who had just walked in off the street or something.) But whenever I measure my BP right after riding to Wallyworld, I find the higher my heart rate, the lower my pressure. For instance, my last few tests were all around 95/65 and 122 bpm. Prior tests where my bpm was closer to 100, results for my BP would hover around 115/75. Is this dynamic unusual, or are the BP monitors at Walmart terribly unreliable?
n.b.: My resting heart rate is pretty high, not much below 100, been that way all my life. (Doctor wanted to put me on beta-blockers but I declined.) So I am a bit of a freak to start with.
Thanks all for any insight.
