Fig 1 Navigator user interface showing target zone (solid yellow lines), patient position (red dot), and recommended manipulation of cardiac determinants (yellow arrow) and present values of cardiac determinants (right-hand column, second field from above). In the navigator group, the investigator had access to the graphical and numerical displays; in the control group, only the right-hand numerical display was visible.
