Performance
Heart Rate Measurement Range
30-220 bpm (beats per minute)
Heart Rate Accuracy
10% or ±5bpm (whichever is greater)
Heart Rate Resolution
1 bpm
Heart Rate Calculation
Heart Rate is calculated:
•
Taking into account last 10 beat-to-
beat intervals
•
Excluding the minimum and the
maximum intervals
•
Averaging the remaining eight
intervals to compute “mean_interval”
and
•
Compute 60/mean_interval (in
seconds) to convert to bpm
Heart Rate Sampling Rate
250 samples per second
Heart Rate Meter Accuracy and
Response to Irregular Rhythm
Provides correct heart rates (60, 80,
90, 120 bpm) using test waveforms
as indicated in ANSI/AAMI EC13 Sec.
4.1.2.1(e). All QRS are counted with test
waveforms within HR accuracy defined
above
Response time of heart rate meter to
change in heart rate
Inside a reporting interval,
instantaneous heart rate change from
80 bpm to 120 bpm shall be captured
within 8 seconds (margin of +2 sec)
