The EMG filter is an adaptive, non-linear and time- variant
low pass filter that is applied to ECG signals. Since EMG is a non-
linear filter, user should be trained by a qualified person to use this
filter.
In some cases, using the EMG filter may affect P, QRS and T waves.
Lowpass and non-linear EMG filter may decrease amplitude
of 10 Hz and higher frequency signals for different morphologies of
ECG signal.
The EMG filter is designed only for ECG signals. In case of
other applications (e.g. calibration), turn off this filter.
Pace Detect: Available options are Off and On. The electrocardiograph system detects and rejects
pacemaker-generated signals from ECG signal, so that they will be ignored in determining heart
rate. If you select On for patients with pacemaker, detected pacemaker signals will be marked on
the ECG waveform as a white vertical line.
For patients with pacemaker, the PACE DETECT function
must be switched "ON", otherwise, the pacing impulse may be
counted as normal QRS complex.
In patients with pacemaker, if the PACE DETECT function is
"OFF", turn off the low pass (25Hz, 35Hz) and EMG filters to
check pacemaker function.
ECG signal saturation occurs when the signal is not displayed
or exceeds lower or upper limits of the display area.
