T’ AMP millivolts T’ wave amplitude
T’ DUR milliseconds T’ wave duration
T’ AREA Ashman
units
(40 ms x 0.1
mV)
Area of the terminal portion of a biphasic T wave.
PR INT milliseconds Interval from the onset of the P wave to the onset
of the QRS complex.
PR SEG milliseconds Interval from the end of the P wave to the onset of
the QRS complex.
V.A.T. milliseconds Ventricular Activation Time: the interval from the
onset of the QRS complex to the latest positive
peak in the complex, or the latest substantial
notch on the latest peak, whichever is later.
QRS PPK millivolts Peak-to-peak QRS complex amplitude.
QRS DUR milliseconds QRS complex duration, measured from its onset
to the ST segment onset (J point).
QT INT milliseconds Interval from the onset of the QRS complex to the
end of the T wave.
GROUP 1 (or 2 - 5) Indicates the rhythm group used to derive the rep-
resentative measurements for each lead. Will be
Group 1 unless no Group 1 beats were detected
during the analysis interval for this lead.
