Figure 1. Demonstration of the teaching mode of the Functional Heart Project. The user can
select the group of cases he or she is interested in seeing by pointing and clicking on one of
the buttons at the right. The computer randomly chooses a case to be shown within the range of
EFs selected. As the images are presented, the ERNA calculated EF is shown to the right of the
ECHO image thus reinforcing the correlation between the image and the EF.
