You might want to check with your doctor immediately. I don't know what your medication situation is but when mine was running that low the doctor reevaluated what I was taking. He weaned me off the Beta Blocker and blood pressure returned to a level that allowed me to gain some strength Mine stays around 115/68 – 125/72 with a pulse in 50-70 range. I do feel better. My HA was 4 years ago with 3 stents. I think it is possible to have a BP too low. I am 75 as well.
