Chapter 5 Connecting ECG Cable
During defibrillation, don’t touch the patient, electrodes, patient cable and lead
terminals. Otherwise it may result in serious injury or death.
For a pacemaker patient, ECG machine may interpret and record the pacemaker
pulse as the QRS complex wave. Please carefully inspect the ECG waveform
recorded by ECG machine.
For a pacemaker patient, pacemaker detection should be activated when set the
machine. Please refer to Section 4.2.2 for details.
Please verify that all electrodes are connected to the correct sites on patient
body. Avoid electrodes (including neutral electrodes) and the patient contacting
the ground or any other electric conductors.
As with all medical equipment, carefully route patient cabling to reduce the
possibility of patient entanglement or strangulation.
Suction ball of chest electrodes contains natural rubber, which may cause
allergy. Please pay close attention to the skin placed with electrodes, if allergy
occurs, please change other types of electrodes.
Automatic measurement and diagnosis are for the doctors’ reference only, and
cannot be directly used as the basis for clinical treatment.
5.1 Environmental Requirements
It is required to keep warm indoors in winter, and the room temperature is no lower than
18 ℃ so as to avoid EMG interference caused by coldness. In summer, open the air
conditioner to control room temperature and to prevent insecure placement of electrodes
cause by the patient’s sweating.
AC power outlet must be connected with dedicated and reliable ground wire. .
When place the ECG machine, try to keep its power cord away from the patient’s bed and
patient cable. Do not place other appliances or power cord near the bed.
