• Interference from an ungrounded instrument near the patient or electrosurgery usage can induce
noise and artifact into the waveforms.
7.3 ECG Display
The following figures show the ECG waveform and numeric areas. The display may be configured to look slightly
different.
7.4 Preparing for ECG Monitoring
7.4.1 Preparing the Patient Skin
Proper skin preparation is necessary to ensure good signal quality at the electrode sites, as the skin is a poor
conductor of electricity. To properly prepare the skin, choose flat areas and then follow this procedure:
1. Shave hair from skin at chosen electrode sites.
2. Gently rub skin surface at sites to remove dead skin cells.
3. Thoroughly cleanse the site with a mild soap and water solution. We do not recommend using ether or
pure alcohol, because this dries the skin and increases the resistance.
4. Dry the skin completely before applying electrodes.
7.4.2 Applying Electrodes and Connecting the Patient
To connect ECG cables, follow this procedure:
(1) ECG lead label of the displayed waveform (2) ECG waveform gain
(3) ECG filter mode (4) Notch filter status
(5) Paced status: If Paced is set to Yes , is displayed. If Paced is set to No, is displayed.
(6) Pace pulse marker: If Paced is set to Ye s , pace pulse markers “|” are displayed corresponding to detected
pacer for each beat.
(1) Parameter label (2) HR measurement unit
(3) HR alarm limits (4) HR value
