If you suspend detection after a tachyarrhythmia detection has occurred and resume
detection before the tachyarrhythmia episode terminates, redetection works somewhat
differently for each type of episode, as follows:
AT/AF episodes – If you suspend detection during a detected AT/AF episode, and then
resume detection before the episode terminates, detection starts over for the same episode.
Note: Suspending tachyarrhythmia detection does not affect Mode Switch. A Mode Switch
may occur whether or not tachyarrhythmia detection has been suspended.
VT/FVT/VF episodes – If you suspend detection while a therapy is being delivered, the
device finishes delivering the therapy that is in progress, but does not redetect until you
resume detection. If you resume detection before the episode terminates, the device begins
redetection, and the episode is redetected if the programmed Beats to Redetect value is
reached.
VT Monitor episodes – If you suspend detection during a detected VT Monitor episode,
and then resume detection before the episode terminates, there will be episode data storage
for 2 episodes, with the first episode terminated while the rate is still fast.
8.10.2 How to suspend or resume detection with the programmer
Figure 180. [Suspend] and [Resume] buttons
The [Suspend] and [Resume] buttons can be used whenever there is telemetry with the
device and the device software is running.
1. To suspend detection, select [Suspend]. The programmer displays a SUSPENDED
annotation on the status bar.
2. To resume detection, select [Resume].
8.10.3 How to suspend or resume detection with a magnet
1. To suspend detection, place the magnet (such as the Model 9466 Tachy Patient
Magnet) over the device.
2. To resume detection, remove the magnet from over the device.
Note: The programming head contains a magnet. When the programmer is using wireless
telemetry, you can suspend detection by placing the programming head over the device.
For more information about establishing telemetry, see Section 4.1, “Establishing telemetry
between the device and the programmer”, page 45.
