Ventricular Indices Statements (if applicable)
These Indices (and numeric comparisons) have ranges which demonstrate an elevated risk of relaxation
abnormalities associated with LV diastolic dysfunction .
If any of the criteria related to the MyoVista Ventricular Indices specified are met, then a statement listed in
Table E-4 will be displayed below the Repolarization Measures Algorithm Statement (see Figure E-8) .
Figure E-8
Table E-4 . Provides the relative-risk calculations for a patient having relaxation abnormalities associated with
LV diastolic dysfunction as opposed to those who do not trigger the rule stated in that row .
