Muscle Sympathetic Nerve Actvity

[pickledfairy]

Never heard of it, but looked it up and it stands for Muscle Sympathetic Nerve Activity....looks like it can be measured during baroflexture testing, etc. One article I could find that defined it stated it is "a direct measure of sympathetic nervous outflow". Don't know if this helps, but I couldn't find much more unless I read a ton of articles....and right now I don't think I would have understood them anyway !

I included a pubmed link in my prior post--click on it for an article that's about msna testing and baroflex response.

This is technical, cardio girl, but it appears to be a test to determine the connection between hypovolemia, sensitivity of the pressure receptors (the body's response to a dropping BP), and the sympathetic system response. I guess they are seeing if you over- or under-react to BP changes. I forget if you have hypovolemia, but don't recall your mentioning it (but I am old), so maybe they are checking to see where the culprit(s) are.

i have been tested for hypovolemia (the green dye test thingy?) and it was normal, so...not hypovolemic issues with me as far as i know....
