Patient Preparation
The ECG traces quality depends very much on the stability and
conductivity of the electrodes during the test, especially during
high stages when the patient movements can cause artifacts.
Here are some basic rules to ensure good electrical contact:
• Shave hair at the electrode contact points.
• Use a special shirt that attached the electrodes and lead
wires to the body.
• Use high quality liquid gel electrodes.
• Make sure that the lead wires do not swing.
Detachable 3 leads each 100cm with clip connectors on the
patient end designed for use with disposable ECG electrodes.
Furthermore, equip 3 repeatable limbs electrode clamps which
can connect with clip connector. Limbs electrodes are white, red
and green (AHA\IEC).
