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 IEC 60601-2-27: 201.12.1.101.13, the
heart rate meter rejects all pulses meeting the following conditions.
Amplitude:
Width:
Rise time:
Input slew rate:
±2 to ± 700 mV
0.1 to 2 ms
10 to 100 µs
2.2 V/s ± 15% RTI
HR
Measurement range Neonate:
Pediatric:
Adult:
15 to 350 bpm
15 to 350 bpm
15 to 300 bpm
Accuracy ±1% or ±1bpm, which ever is greater
Resolution 1 bpm
Sensitivity 200 V (lead II)
Heart rate averaging In compliance with the requirements in Clause 201.7.9.2.9.101 b) 3) of IEC
60601-2-27, 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 screen is updated every second.
Response time to heart rate change Meets the requirements of IEC 60601-2-27: Clause 201.7.9.2.9.101 b) 5).
