Three different methods are used:
Normally, heart rate is computed by averaging the 12 most
recent RR intervals.
For runs of PVCs, up to 8 RR intervals are averaged to compute
the HR.
If each of 3 consecutive RR intervals is greater than 1200 ms
(that is, rate less than 50 bpm), then the 4 most recent RR
intervals are aver\-aged to compute the HR.
HR change from 80 to 120 bpm:
Range: [6.4 to 7.2 seconds] Average: 6.8 seconds
HR change from 80 to 40 bpm:
Range: [5.6 to 6.4 sec] Average: 6.0 seconds
Ventricular bigeminy: 80 bpm
Slow alternating ventricular bigeminy: 60 bpm
Rapid alternating ventricular bigeminy: 120 bpm
Bidirectional systoles: 90 bpm
Methods A and D were used to establish overall system error
and frequency response.
Rejection of pacemaker pulses with amplitudes from ±2 mV to
±700 mV and widths from 0.1 ms to 2.0 ms (Method A)

Delay
max. 14 seconds
for limits from 0 to 20 rpm:

for limits above 20 rpm: max.
