Re: Question about Echo


Valve openings, chamber sizes, etc. are measured. For instance heart chambers are measured by a transducer (manually controlled) by outlining the chamber size during peak of relaxation and again before contraction. Then the echo software calculates chamber size. I watched and questioned the tech during the test, and it is obvious chamber size is not precise because the edges of the chambers shown on the screen to be outlined are somewhat "fuzzy". There would be a margin of error of a few points up or down.

When questioned I have found the techs to be helpful in explaining the procedure and what they are seeing. If not asked I believe the tech will not volunteer comment on any findings or opinions. They certainly will not give any advise on or recommend any treatment or make a dx. Because the tech did not mention any results does not mean something bad or something good is going on.
