A diagnostic gauge for cardiac health is described. Multiple parameters
pertaining to a patent's cardiac health are distilled to a single
diagnostic vector having an angle and a magnitude. The diagnostic vector
is plotted on a Cartesian graph to form a visual gauge that provides a
general assessment of the patient's cardiac health given the underlying
parameters. This allows care providers to diagnose more quickly a
patient's cardiac health through observation of the gauge without having
to review all of the measured parameters. Additionally, the diagnostic
gauge can be used to screen for those patient's with conditions that
require more immediate attention. A trend of the diagnostic vectors can
also be developed and plotted to reveal changes in the patient's cardiac
health over time.
