Hi, My HR , increases 8-10 points @ 1 minute, stays basically constant until the nitro. But did increase as a result of the nitro, which is normal. @ 2-3 minutes after the nitro it was in the low 40's. The B/p 2-3 minutes after nitro, is written as 82/50 blank 0/P 52/P I had 4 TTTs. I have orthostatic hypo tension also. I was basically disabled until I was put on Norpace and I really do know know what well feels like. I function great. I manually control my BP. Which basically means I never stop moving and I wear compression stockings. When not doing so I feel heavy and weak. I keep coming in here to clarify or add, but thought I should also mention that my B/P and H/R increase when I lay down. That is during the TTT it does.
