The heart rate calculation operates with irregular rhythms of IEC 60601-2-27 6.8.2 bb 4, the heart rate
after a 20 second stablization period as follows:
Figure 101 A1): 80 bpm
Figure 101 A2): 59 bpm
Figure 101 A3): 122 bpm
Figure 101 A4): 117 bpm
Pacemaker pulse detection:
detection level:
pulse duration:
Pacemaker detector may not operate correctly during the use of high-frequency (HF) surgical equipment.
The disturbances of HF surgical equipment typically cause false positive pacer detection.
Direct current for leads-off detection
through an active patient electrode:
1 The isolation barrier capacitance in the module has been minimized to reduce the hazard of burns in the event of a
defect in the ESU return electrode connection.
2 When the heart rate (HR) changes rapidly, the averaging is restarted.
