MAGNET TEST
The magnet test gives an indication of the cell capacity, atrial and/or ventricular capture,
amplitude and basic rate programmed without using the programmer. Application of a magnet
over the pacemaker makes the pulse generator operate in a simple safety mode.
Magnet On
When a magnet is applied over the pacemaker, the pulse generator finishes the cycle in
progress and then switches to the magnet test mode described below:
Mode
DOO (if mode programmed: Dxx or SafeR for the DR model
only)
VOO (if mode programmed: Vxx)
AOO (if mode programmed: Axx)
Rate Magnet rate
Pulse amplitude 5 V (or greater if the programmed amplitude value is greater)
Pulse width 0.5ms (or greater if the programmed pulse width value is
greater)
AV delay (for the DR model
only)
Rest AV delay
Magnet Off
On exiting magnet mode, the device operates:
― for 6 cycles by pacing at the magnet rate, with an AV delay of 95ms (if applicable
and for the DR model only) and with the programmed amplitude and pulse width in
asynchronous mode,
― then for 2 cycles with the programmed parameters, in asynchronous mode.
CAPTURE TEST MODE:
The purpose of this test is to demonstrate that the programmed voltage and pulse width are
sufficient to capture. During the capture test, the pacemaker operates as follows:
Mode
DOO (if mode programmed: Dxx or SafeR for the DR model
only)
VOO (if mode programmed: Vxx)
AOO (if mode programmed: Axx)
Rate Magnet rate
Pulse amplitude and width As programmed
AV delay (for the DR model
only)
94ms
