30-220 bpm (beats per minute)

1 bpm
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
250 samples per second
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
Inside a reporting interval,
instantaneous heart rate change from
80 bpm to 120 bpm shall be captured
within 8 seconds (margin of +2 sec)
