Echo reference values?

Hi!

I was just wondering what reference values you use for a normal 2D-guided M-mode echocardiogram. The values I've found online are somewhat different.

Thank you!

Hello,
As strange as it sounds, normal values vary by echo lab.  If the lab that did your echo provided you with values, you should use those.  The other thing I would caution you about is that it is difficult to know what these numbers actually mean.  It is easy to get upset about a value that is not clincally significant is outside the normal range.
SD = standard deviation.
SD means that 95% of normal populations has values in this range, but it is still possible to have normal values slightly outside the range depending on clinic cirucmstances.

                             Female             Male
                         value        SD      value      SD
LV diastolic dimension:   50.8        3.6      70.9       7.5
LV systolic dimension     35.9        3.4      28.9       2.8
LV wall thickness         18.1       2        15.5       1.5
LA dimension              37.5       3.6      33.1       3.2

these numbers on are in mm

These values are from The Echo Manual by Jae K Oh from the Mayo Clinic.

I hope this helps.  thanks for posting.

Thank you!

However, I have difficulty understanding the values for LV dimensions. 70.9 sounds a little bit to large for a normal value? :)

And reference values mean mean + - 2 SD is equall to 95 %, right?

you are right
46.1 is the correct value (70 was in the row above).

+/- 2 SD is equal to 95%, correct.
