Chapter 5: ECG Monitoring User Manual
5-16
■ ECG GAIN
To adjust the size of ECG waveform, select gain value for each lead from ×0.25, ×0.5, ×1, ×2,
×4 and AUTO. In "AUTO" mode, the monitor chooses an appropriate gain automatically.
■ ECG SWEEP
Available options for ECG SWEEP speed are 12.5, 25, and 50 mm/s.
■ ECG FILTER
For noises reduction, smoother waveforms or detailed waveforms, there are three options
for filtering the ECG:
FILTER TYPE FREQUENCY RANGES APPLICATION
NORMAL
0.5-40HZ This mode is applicable in normal situation
EXTENDED
0.05-100HZ
In diagnostic application. but the ECG
waveform might have some noises
MONITOR
0.5-24HZ
This mode may reduce interference from
Electrosurgery equipment or can be used
when the system has high noises or doesn't
have equipotential earth.
■ HR AVERAGE
Available options for HR AVERAGE are 4, 8 and 16 sec.
To calculate HR value average, the values are sent per second to averaging section and any
change based on user setting is made in output data.
- Response time of Saadat monitor to HR change with regard to different HR averages is as
follows:
■
Response Time
HR Avg.= 16s HR Avg.= 8s HR Avg.= 4s
11 6 5 HR= 80 to 120 BPM
13 8 7 HR= 80 to 40 BPM
