ECG Signal Processing and Display
The monitor identifies QRS complexes with amplitudes between 0.2 and 5.0 mV and a QRS width of 70
to 120 ms for adults (or 40 to 120 ms for neonates). It calculates heart rates within a range of 15 to 300
beats per minute, using the R-R intervals of the last 10 seconds and diisregarding the two longest and two
shortest R-R intervals. It averages the remaining intervals, and displays the result as the current heart rate
in the HR parameter box on the main screen.
