3.2 Preparing the Patient 

3.2.1 Instructing the Patient 

Before attaching the electrodes, greet the patient and explain the procedure. Explaining the 

procedure decreases the patient’s anxiety. Reassure the patient that the procedure is painless. 

Privacy is important for relaxation. When possible, prepare the patient in a quiet room or area 

where others can’t see the patient. Make sure that the patient is comfortable. The more relaxed 

the patient is, the less the ECG will be affected by noise. 

3.2.2 Cleaning the Skin 

Thorough skin preparation is very important. The skin is a poor conductor of electricity and 

frequently creates artifact that distorts the ECG signal. By performing methodical skin 

preparation, you can greatly reduce the possibility of the 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 clean 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. 

3.3 Connecting the Patient Cable to the 

Electrocardiograph and Electrodes 

WARNING 

The performance and electric shock protection can be guaranteed only if original patient 

cable and electrodes of the manufacturer are used.
