-Each echocardiogram is an evaluation of the LV dimensions, wall thicknesses and function.
+Each echocardiogram should include an evaluation of the LV dimensions, wall thicknesses and function.
-There has to be conducted several (read: different) measurements to be a good estimate of LV function.
+Several (read: different) measurements have to be performed from different views to asses a good estimate of LV function.
