3.3 Preparing the Patient
3.3.1 Instructing the Patient
Give necessary guidance to patients before they leave:
1. Show them how to use events button and explain when to press the button;
2. Explain to the patients or nursing staff the importance of registering patient log timely and
completely. Introduce writing format, contents, what to record, recording time, location,
activities and self-feeling in detail;
3. Warn patients:
♦ Do not get the recorder wet. No bathing, shower or shampooing;
♦ Do not touch electrodes or unplug leads.
♦ Do not open recorder. Do not take out battery or SD card;
♦ Do not place mobile, TV or other electrical appliances one meter around the recorder.
♦ Do not place heat source like heater close to the recorder.
4. Tell them to stop recording when they feel extremely uncomfortable and tell them how to
stop;
5. Let them revisit 24 hours (48 hours or longer) later.
3.3.2 Preparing the Skin
Thorough skin preparation is very important. The skin is a poor conductor of electricity and
frequently creates artifacts that distort the ECG signals. By performing methodical skin
preparation, you can greatly reduce the possibility of noise caused by muscle tremor and baseline
drift, ensuring high-quality ECG waves. There is natural resistance on the skin surface due to dry,
dead epidermal cells, oils and dirt.
To Prepare the Skin
1. Shave hair from electrode sites, if necessary. Excessive hair prevents a good connection.
2. Wash the area thoroughly with soap and water.
3. Dry the skin with a gauze pad to increase capillary blood flow to the tissues and to remove
the dead, dry skin cells and oils.
NOTE: If you don't have enough time for the steps above, you can use pledget to scrub
the electrode sites to remove the dead, dry skin cells and oils and increase
capillary blood flow to the tissues.
