measured using the M3001A
measurement server and the M1020B measurement module.
Complies with EN ISO 9919:2005 (except alarm system; alarm system complies with IEC 60601-2-
49:2001).
Heart Rate Averaging Method 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 averaged to compute the HR.
Response Time of Heart Rate Meter to Change in
Heart Rate
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
Heart Rate Meter Accuracy and Response to
Irregular Rhythm
Ventricular bigeminy: 80 bpm
Slow alternating ventricular bigeminy: 60 bpm
Rapid alternating ventricular bigeminy: 120 bpm
Bidirectional systoles: 90 bpm
Accuracy of Input Signal Reproduction Methods A and D were used to establish overall system error
and frequency response.
