3.1 ECG ACQUSITION
3.1.1 ECG PATIENT CABLE CONNECTION AND ELECTRODES PLACEMENT
The ECG is a record of the electrical activity of the heart. The ECG is obtained by placing either STANDARD
ELECTRODES or DISPOSABLE ELECTRODES on the patient's chest and allows the heart's electrical activity to
be monitored and recorded. ECG monitoring allows to identify and interpret the cardiac rhythms or
dysrhythmias and measurement of heart rate (HR).
ECG Electrode Requirements
Electrode quality is critical for obtaining an undistorted ECG signal. Always check the date code on
electrode packages for the "Use By date" before applying the electrodes to a patient. Do not use electrodes
with expired "Use By date" codes. Disposable electrodes are intended for a single use.
For best ECG monitoring results, use silver/silver chloride (Ag/AgCl) electrodes.
Other types of electrodes will display the post-defibrillation ECG in less time than expected.
Possible misinterpretation of ECG data.
The frequency response of the monitor screen is intended only for basic ECG rhythm identification; it does
not provide the resolution required for diagnostic and ST segment interpretation. For diagnostic or ST
segment interpretation, or to enhance internal pacemaker pulse visibility, attach the ECG cable and then
print the ECG rhythm.
3.1.2 PROCEDURE
1. ECG ELECTRODES ATTACHMENT
Follow the drawings below for the disposable ECG electrodes position on the patient's body.
