Comply with the requirements of YY 1079-2008 Part 4.1.2.1 d). The average
heart rate has been calculated as follows:
If the last three consecutive RR intervals are greater than 1200 ms, the 4
closest RR intervals are averaged to calculate heart rates. Otherwise, take the
12 closest RR intervals, subtract the maximum and minimum values, and take
the average to calculate the heart rate.
The heart rate value displayed on the screen is refreshed every second
Accord with the requirements of YY1079-2008 Part 4.1.4.1 and 4.1.4.3, pulses
that meet the following conditions are suppressed:
Amplitude: ± 2- ± 700 mV
Width: 0.1- 2 ms
Rise time: 10- 100 μs
Minimum input pendulum rate: 10 V/s RTI
