Magnet Response - BIOTRONIK Evity 6 Manuel Technique

• Take possible interruption of automatic Active Capture Control into consideration.
• In the case of follow-ups and threshold tests, take loss of synchronized ventricular
pacing into consideration.
• Mode Switching does not allow exclusive left ventricular pacing; consider the
consequences when setting Mode Switching parameters.
If an ICD is implanted at the same time, do not permit unipolar pacing
If an ICD is implanted in addition to a pacemaker and a lead failure occurs, it is possible
to switch to unipolar pacing after resetting the pacemaker or using the automatic lead
check. As a result, the ICD could falsely inhibit or trigger tachyarrhythmiatherapy
activity.
• Unipolar leads are not permitted in this configuration.
Recognizing lead failure
Automatic impedance measurement is always switched on.
• Impedance values that indicate technical failure of a lead are documented in the
event list.
Consider power consumption and service time
The pacemaker permits programming of high pulse amplitudes with long pulse widths
at high rates to be able to adequately treat even rare diagnoses. In combination with
low lead impedance, this results in a very high level of power consumption.
• When programming large parameter values, take into account that the replace-
ment indication ERI will be reached very early because the service time of the
battery may be reduced to less than 1 year.
Home Monitoring: The CardioMessenger should be relatively close to the patient; if it is
too far away, the device constantly seeks and consumes more power than necessary.
• Home Monitoring ON reduces the service time by approximately 15% in single- and
dual-chamber devices and by approximately 10% in triple-chamber devices.
Wandless telemetry: 15 minutes of usage reduces the service time by approximately
7 days.
• Do not establish unnecessary wandless telemetry.
• After 5 min without input, the device switches to the economy mode.
• Check the battery capacity of the device at regular intervals.

Magnet Response

Programming head application
When the programming head is applied, time remains for device interrogation before
the device switches back to the previously set permanent therapy mode. The same
applies to programming head application to establish wandless telemetry contact.
Magnet response in standard program
Applying a magnet or the programming head can result in an unphysiological rhythm
change and asynchronous pacing. The magnet response is set as follows in the
standard program of BIOTRONIK pacemakers:
• Asynchronous:
For the duration of the magnet application – mode D00 (where applicable V00 / A00)
without rate adaptation;
Magnet rate: 90 bpm
• Automatic:
For 10 cycles – mode D00, subsequently mode DDDR;
Magnet rate: 10 cycles with 90 bpm, subsequently set basic rate
• Synchronous:
Mode DDDR (VVIR as the case may be);
Magnet rate: set basic rate
Note: See also the replacement indication information for magnet response at ERI.
Magnet application by patients
If patients are performing their own magnet application, the synchronous magnet
response must have been programmed. Patients should also know the following:
• When may the magnet be used?
In cases of severe dizziness and indisposition.
• How long is the magnet placed on the pacemaker?
1 to 2 s.
• What happens when the magnet is applied?
The IEGM of the last 10 seconds is stored.
• What has to happen after magnet application?
The patient has to contact the physician for a follow-up.
