Chapter 6 ECG Acquisition and Recording
6.1 Acquisition Preparation
To secure the patient and to record stable accurate electrocardiogram (ECG), please carefully
check the following items before you power on the machine for measurement.
1）Check whether the exam room is appropriate;
 Whether there are apparatuses such as X-ray machine, ultrasound system and so forth in
the patient room, as they may interfere with each other;
 Whether the ground is well connected;
 Whether room temperature and humidity are suitable; temperature would better be in the
range of 20 ~ 25℃, ambient humidity would better be in the range of 30% ~ 60%.
2） Whether the power is well connected.
 Whether the power plug is loose;
 Whether the power cord is intertwined;
 Whether the power is sufficient if supplied by battery.
3）Whether the lead wires are well connected.
 Whether the plug is loose;
 Whether the patient cable stays too close to the power cord;
 Whether the lead wires and electrodes are well connected;
 Whether electrodes are installed loosely, or adjacent electrodes have contact with each
other.
4）How is the patient?
 Whether the patient is too nervous; whether he or she moves or talks
 Whether the patient’s hands or feet contact metal objects such as bed edges.
