When the filter mode is changed, a notch will appear on the ECG waveform due to
the change in frequency characteristic.

Impedance Respiration Measurement
The respiration measurement using the impedance method conducts high-frequency and weak current
between the ECG electrodes attached to the patient, and measures the potential difference between
the electrodes caused by thoracic movement using the synchronous rectification system. For a patient
using the adaptive (minute ventilation) pacemaker, the pacemaker measurement signal and the
high-frequency current of this equipment interferes with each other which causes incorrect respiration
measurement.
If the patient is using an adaptive (minute ventilation) pacemaker, set the impedance respiration
measurement to OFF.

Select ON or OFF for impedance respiration measurement.
ON will perform impedance respiration measurement.
OFF will stop the impedance respiration measurement.
●
Pacemaker Usage
If the patient is wearing a pacemaker, the monitor will identify the pacemaker pulse and insert an
artificial pulse onto the ECG waveform for easy identification. By detecting the pacemaker pulse, it
prevents to erroneously detect QRS as a pacemaker pulse when pacing waveform does not appear
(pacing failure). The arrhythmia analysis analyzes pacing beat as P (pacemaker beat) or F (fusion
beat) to prevent erroneous judgment of VPC.

The pacemaker usage selection influences the precision of the QRS
detection and arrhythmia analysis. Make sure the correct selection is
made.

Rate meters may continue to count the pacemaker rate during
occurrences of cardiac arrest or some arrhythmias. Do not rely entirely
upon rate meter alarms. Keep the pacemaker patients under close
surveillance. See this manual for disclosure of the pacemaker pulse
rejection capability of this equipment.
