5)Whether instruments are in good condition.
Whether the ECG machine is damaged;
Whether ECG machine is inspected and maintained regularly:
Whether recording paper is sufficient.
6.2 Acquisition and Recording
6.2.1 Recording Setting
After the checks are all right, power on the ECG machine, it enters into Waveform Acquisition
interface, and then you can observe the waveform when they become stable. With reference to
Chapter 4 System Setting set the sampling mode, layout, gain, and paper speed on actual
needs, and then press key to print ECG waveform. The system will automatically
acquire the waveform and generate the patient report.
On Waveform Acquisition interface, press shortcut keys , , to set paper
speed, gain, and filter. In manual mode, press key to change leads. For other settings,
refer to Section 4.2. If the layout is selected with rhythm lead, set it in [12-lead]. For details,
please refer to Chapter 4.
When ECG signal is just connected or the machine receives overload noise,
waveform will be chaotic, baseline drift will be severe, and waveform
amplitude may exceed the maximum width. At this moment, please wait until
the machine is connected, the patient calms down, and waveform displayed
on the interface become stable, then start measuring and recording.
When the ECG machine is overloaded or any part of the amplifier is saturated,
or ECG machine works abnormally, at this moment, only baseline is displayed
on the interface. In order to achieve accurate results, please wait until the
machine is connected, the patient calms down, and waveform displayed on
the interface become stable, then start measuring and recording.
