I have been amazed at the correlation (and sometimes lack of correlation) between my hr and bp. They both go up
when I exercise, but it is exercises that moves up
and down against gravity or that uses larger muscle groups that seem to raise my pressure. For example, I can go ninety to nothing on the elliptical and never get my bp too high (hr gets very high). If I try to run--forget it, zoom, my bp is in the danger zone, but my hr is still pretty low!
