Pace Pulse
Pace pulse markers
Pace pulses meeting the following conditions are labelled with a
PACE marker:
Amplitude:
Width:
Rise time:
±2 to ±700 mV
0.1 to 2 ms
10 to 100 μs
Pace pulse rejection
When tested in accordance with the IEC60601-2-27:
201.12.1.101.13, the heart rate meter rejects all pulses meeting
the following conditions.
Amplitude:
Width:
Rise time:
±2 to ±700 mV
0.1 to 2 ms
10 to 100 μs
HR
Measurement range
Neonate:
Pediatric:
Adult:
15 to 350 bpm
15 to 350 bpm
15 to 300 bpm
Resolution 1 bpm
Accuracy ±1 bpm or ±1%, whichever is greater.
Sensitivity 200 V (lead II)
HR averaging method
In compliance with the requirements in Clause 201.7.9.2.9.101
b) 3) of IEC60601-2-27, the following method is used:
If the last 3 consecutive RR intervals are greater than 1200 ms,
the 4 most recent RR intervals are averaged to compute the HR.
Otherwise, heart rate is computed by subtracting the maximum
and minimum ones from the most recent 12 RR intervals and
then averaging them.
The HR value displayed on the monitor screen is updated every
second.
