Chapter 4: Preparation

Patient preparation

Before you start recording the ECG, note the following:
 Give the patient enough time to relax after lying on the bed.
 Electrodes should be placed in suitable and prepared areas.
 The ambient temperature should be appropriate and the patient should not suffer from cold
and tremors.
 Use enough gel.
 Make all necessary settings on the device before recording.
 At the time of recording, the patient is asked to be as calm and still as possible, not to speak
and not to contract her/his muscles.
 At the end of the recording or at least at the end of the work shifts, accessories, especially the
suction chest electrodes and clamp, should be cleaned.
 If the patient has Pacemaker, the Pace Detect option must be ON.

ECG Electrodes Connection

ECG cable consists of two parts: main cable that is connected to the device and lead wires that are
connected to the patient
Warning
When you connect the cables and electrodes, make sure that no metal part is in contact
with the safety ground. Verify that all ECG electrodes are correctly attached to the patient.
Warning
Interference from a non-grounded instrument near the patient and/or ESU (Electrosurgical
Unit) interference can cause inaccuracy of ECG waveform.
Warning
Use only the manufacturer recommended ECG cable with internal resistance. Other ECG
cables and leads may cause improper performance and/or provide inadequate protection
during defibrillation.
