Use with a Pacemaker
When monitoring a pacemaker patient, the transmitter detects pacemaker pulse and rejects the
pacemaker pulse from the heart rate count.

WARNING
Interaction Between Minute Ventilation Rate-Adaptive Pacemakers and Cardiac
Monitoring and Diagnostic Equipment*
The bioelectric impedance measurement sensor of a minute ventilation rate-adaptive
implantable pacemaker may be affected by transmitter which is connected to the
same patient. If this occurs, the pacemaker may pace at its maximum rate and the
transmitter may give incorrect data to the monitor. If this occurs, disconnect the
electrode leads from the patient or change the setting on the pacemaker by referring
to the pacemaker’s manual. For more details, contact your pacemaker representative
or Nihon Kohden representative.

* Minute ventilation is sensed in rate-adaptive pacemakers by a technology known as bioelectric
impedance measurement (BIM). Many medical devices in addition to pacemakers use this
technology. When one of these devices is used on a patient with an active, minute ventilation
rate-adaptive pacemaker, the pacemaker may erroneously interpret the mixture of BIM signals
created in the patient, resulting in an elevated pacing rate.

WARNING
The transmitter detects the pacemaker pulse and rejects the pacemaker pulse from
the heart rate count. However, all of the pacemaker pulse might not be rejected. If
the pacemaker pulse is not rejected, the pacemaker pulse is detected as QRS and
false heart rate may be indicated. Keep pacemaker patients under close observation.

* For the pacemaker pulse rejection capability of ZM-520PA/521PA/530PA/531PA transmitter
refer to the “Specifications - ECG” section.
WARNING
The pacemaker pulse can be overlooked or detected as QRS. You cannot confirm
the pacemaker operation only from the detected pacemaker pulse.

NOTE
• If an electric blanket is used and incorrect heart rate is displayed on the monitor, turn
off the pacing spike detection on the monitor.
