A-8
Response to irregular rhythm
In compliance with the requirements in Clause 201.7.9.2.9.101
b) 4) of IEC60601-2-27, 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
Response time to heart rate
change
Meets the requirements of IEC60601-2-27: Clause
201.7.9.2.9.101 b) 5).
From 80 to 120 bpm: less than 11 s
From 80 to 40 bpm: less than 11 s
Time to alarm for tachycardia
Meets the requirements of IEC60601-2-27: Clause
201.7.9.2.9.101 b) 6).

Tall T-wave rejection
capability
When the test is performed based on Clause 201.7.9.2.9.101 b)
2)of IEC60601-2-27, 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.
