Agilent Technologies provides two standard criteria programs, adult and pedi-
atric, for the PageWriter 300pi cardiograph. Patient information, including
age, sex, height, and weight can be used by the criteria programs in selecting
the interpretive statements.
NOTE For more information about interpretation, see the Interpretive Cardiograph
Physician’s Guide.
How the PageWriter 200/300pi Measures ECGs
The PageWriter 200/300pi calculates measurements for all the waveforms
that you see on the Auto 3 x 4 report. Every beat in every lead is measured
individually, allowing the natural variations among beats to contribute to the
representative measurements. This is in contrast to other measurement meth-
ods in which a representative beat is constructed and then measurements are
made only for the constructed beat. In the PageWriter 200/300pi cardiograph,
representative group, lead and global measurements are calculated from com-
binations of the comprehensive set of measurements for each beat.
