HOW TO USE THE ECG PATIENT CABLE CONNECTION AND ELECTRODES
PLACEMENT
The ECG (electrocardiogram) is a recording of the electrical activity of the heart. The ECG is
obtained by placing either electrodes or paddles on the patient 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 calculation of heart rate.
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.
ECG CONNECTION
Connect the patient cable in its proper port ‘ECG’, placed on the frontal panel of the device.
