Normal Chamber Quantitation Values

Ranges for normal dimensions of common structures are delineated in the table below. Note that though M-mode has long been used for measurement of LV dimensions, 2-D measurements are likely more reliable and are being used with increasing frequency as the standard measurements at many institutions.
