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:
±2 to ± 700 mV
0.1 to 2 ms
10 to 100 µs
HR
Measurement range Pediatric:
Adult:
15 to 350 bpm
15 to 300 bpm
Accuracy ±1% or ±1bpm, which ever is greater
Resolution 1 bpm
Sensitivity 200 V
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).
From 80 to 120 bpm:
From 80 to 40 bpm:
less than 11 s
less than 11 s
Time to alarm for tachycardia Meets the requirements in Clause 201.7.9.2.9.101 b) 6) of IEC 60601-2-27.

Arrhythmia Analysis Classifications Asystole, V-Fib/V-Tach, PNP, PNC
Tall T-wave rejection capability When the test is performed based on Clause 201.12.1.101.17 of IEC 60601-2-
27, the heart rate meter will reject all 100 ms QRS complexes with less than
1.2 mV of amplitude, and T waves with T-wave interval of 180 ms and those
with Q-T interval of 350 ms.
Lead-off detection current ≤0.1 A
Baseline recovery time <2.5 s (after defibrillation, in therapy mode)
Response to irregular rhythm In compliance with the requirements in Clause 201.7.9.2.9.101 b) 4) of IEC
60601-2-27, the heart rate after 20 seconds of stabilization is displayed as
follows:
Ventricular bigeminy (3a): 80±1 bpm
Slow alternating ventricular bigeminy (3b): 60±1 bpm
Rapid alternating ventricular bigeminy (3c): 120±1 bpm
Bidirectional systoles (3d): 90±2 bpm
