leads off: one or more lead names appearing in the
upper-left corner of the screen and printer report
indicates that those leads are not making a good
connection with the patient. Leads off is also seen on
the screen and printed report as a dotted line trace.
measurements: the amplitudes, durations, areas,
and intervals that characterize the ECG waveform.
(Menu key): the cardiograph key that
displays the configuration menu selections on the
cardiograph’s front panel display.
modem: a device that converts data from an
electronic device into signals that can be carried by
telephone line to another location where it is received
by another modem and converted to data for use in
another electronic device.
modemSCP: transmission by modem, using
Standard Communications Protocol, as described in
the European Committee for Standardization,
Standard Communications Protocol - Computer -
Assisted Electrocardiography, (CEN/TC 251).
operator: the person who records ECGs.
overread: to review an ECG report. This review
must be completed by a qualified physician.
patient cable: the patient lead set and instrument
cable. The patient cable connects the cardiograph to
the electrodes attached to the patient.
pediatric criteria: the interpretive rules used when
analyzing ECGs of persons aged 15 years or younger.
post view: to retrieve an ECG from the internal
memory and display it on the LCD display.
pre-acquisition: Agilent term for acquiring ten
seconds of ECG before the operator presses the
key.
preview screen: the LCD display screen that shows
the ECG traces as they will appear on the printed ECG
report.
Rhythm ECG: an ECG report format which shows
one-lead 60-second waveforms.
rhythm strip: the ten second recording of a
particular lead that is printed at the bottom of an Auto
ECG report.
SCP: Standard Communications Protocol, a data
transmission standard, as described in the European
Committee for Standardization, Standard
Communications Protocol - Computer - Assisted
Electrocardiography, (CEN/TC 251).
softkeys: the labels or commands assigned to the
function keys. The softkeys appear at the bottom of
the front panel display, and are executed when the
corresponding function key is pressed. These keys are
noted in this manual as softkeys.
standard leads: the conventional twelve lead set
order is I, II, III, aVR, aVL, aVF, and V1 through V6.
Welsh cups: reusable chest electrodes held in place
by suction cups. Limb plate electrodes are used on the
arms and legs when Welsh cups are used on the
patient’s chest.
