Yes, I think this wqveform does look externalised,
The way to be sure is to compare with the distal CCA waveform on the other side.
The one on the other side should be a lower resistance waveform.
upload that waveform if you have it handy.
3 lectures are being uploaded now,
One on the foetal heart,
A short one on tennis leg injury assessment,
and a 30 minute lecture called 360 degrees around the elbow
I recorded it for the Korean Pain physicians meeting that was this weekend in Seoul.
I could not attend so recorded the material for them and then did a question and answer session from my home.
The material is similar to the elbow material I have already recorded but there are some new cases and ideas.
