Chapter Purpose
This chapter is intended to provide the user with:
• Display overview.
• Overview of patient demographic entry.
• Instructions to acquire an ECG.
• Instructions to print an ECG.
• Instructions to store an ECG.
• Rhythm printouts.
Display Overview
The CP 20 features a 320 x 240 pixel LCD display for valuable preview of ECG waveform, function key
labels and other parameters as explained below:
• Heart Rate: When a patient is connected to the cardiograph, his/her heart rate is displayed in
real-time. The heart rate is the average ventricular rate measured over an average of the
patient’s last five beats.
NOTE: If a lead fail occurs, an indicator flashes in this location.
• Speed: Use Speed (F3) to select one of the various options for display and rhythm printout
speed : 5mm/s, 10mm/s, 25mm/s, 50mm/s. Acquired ECGs can be printed at 25mm/s or
50mm/s. ECGs selected from memory can only be printed at the default speed of 25mm/s.
• Gain: Use Gain (F4) to select waveform amplitude for display and printout: 5mm/mV, 10
mm/mV, 20 mm/mV
• Filter: Use Filt (F5) to select the low-pass filter options: 40Hz, 150Hz, 300Hz for ECG
printouts.
• Clock: Time display with hour, minutes and seconds resolution. (See section 2 for setting a
new date and time). When the ECG is acquired, the time displayed is the printed ECG
acquisition time.
