6-12 ECG and Arrhythmia Monitoring
Changing the Size of the ECG Wave
If any of the displayed ECG waves is too small or clipped, you can change
the size of the ECG waves on the screen.
Changing the adjustment factor only changes the visual appearance of the
ECG wave on the MX40. It does not affect the ECG signal analyzed by the
algorithm.
Comparing the wave size to the 1 mV calibration bar on the ECG wave
segment can help you get an idea of the true ECG signal strength.
To change the size of the ECG waves on the screen by
a fixed adjustment factor:
1 Touch the HR parameter.
2 In the Setup ECG menu, scroll to the second page and select Adjust
Size.
3 Select the required adjustment factor from the list.
Size X1/2 to halve the wave size
Size X1 to display the wave without zoom
Size X2 to double the wave size
Size X4 to multiply the wave size by four
or
4 Touch the ECG wave and enter the size from the Change Wave menu.
5 Select the required adjustment factor from the list.
