Response to irregular rhythm In compliance with the requirements in Clause 201.7.9.2.9.101 b) 4) of IEC
60601-2-27: 2011, the heart rates for the specified test signals after 20 seconds
of stabilization are:
Ventricular bigeminy (waveform A1): 80±1 bpm
Slow alternating ventricular bigeminy (waveform A2): 60±1 bpm
Rapid alternating ventricular bigeminy (waveform A3): 120±1 bpm
Bidirectional systoles (waveform A4): 90±2 bpm
Response time to heart rate change Meets the requirements of IEC 60601-2-27: 2011: Clause 201.7.9.2.9.101 b) 5).
