QRSNTCH + or - Indicates a notch in the QRS complex.
A + indicates a notch or slur in the R or R’ wave.
A - indicates a notch or slur in the Q, S, or S’
wave.
DELTA Yes or No Indicates the presence or absence of pronounced
delta waves preceding QRS complexes.
ST ON millivolts Elevation or depression at the onset (J point) of
the ST segment.
ST MID millivolts Elevation or depression at the midpoint of the ST
segment.
ST 80ms millivolts Elevation or depression of the ST segment 80 ms
after the end of the QRS complex (J point).
ST END millivolts Elevation or depression at the end of the ST seg-
ment.
ST DUR milliseconds ST segment duration.
STSLOPE degrees ST segment slope. Slope is measured in degrees
and can range from 0 to ± 90 degrees
STSHAPE -, V, or ^ The ST segment shape:
- = Straight
V = Concave upward
^ = concave downward
T AMP millivolts T wave amplitude
T DUR milliseconds T wave duration
T AREA Ashman
units
(40 ms x 0.1
mV)
T wave area for monophasic T waves or the area
of the initial portion of a biphasic T wave.
T NOTCH Yes or No Indicates the presence or absence of a notch in the
T wave.
