Something odd just happened. Normally I have a resting heart rate in the high 40s or low 50s. There have been occasions when everything seems to go out of control and I get a resting heart rate in the 90s, but not many (that I have measured at any rate). Normally when I stand I get a pretty immediate jump up to the resting + 30 or more. Today, a couple of hours ago, I got up from a rest and took my standing heart rate and it was only in the 50s. Or rather I measured it the way I normally do (with a pulse oximeter) and the first reading was 70 and it promptly fell to the low 60s, but I felt odd so I got out my wrist based blood pressure meter and tested my heart rate and blood pressure by this point my heart rate was in the 50s and my blood pressure was +20mm for both systolic and diastolic. I know that the wrist based meters are only designed for sitting down, so I was misusing it, and I was not able to stand completely still, I wobbled back and forth a little, but this seemed very odd. I have been consuming more salt water than usual, and have been feeling a greater need than usual so that could be part of the reason I guess, But I was just wondering if someone with a better handle on orthostatic intolerance/dysautonomia could comment.
