Conducting an Activity Threshold Test
Preparing the Patient
The following procedure involves programming and interrogating the
patient’s pacemaker. The patient should be comfortably seated and be in a
resting state prior to the start of this test.
For this test, the patient’s pacemaker can be operating in either an Activity
or non-Activity pacing mode. During non-Activity modes, the sensor
continues to operate in the background. If the pacing mode is an Activity
mode, lower rate should be programmed to its appropriate permanent
setting.
Test Procedure
To execute the Activity Threshold test:
1. Select the [
ACT THRESHOLD TEST
] button on the Activity Tests screen.
2. With the patient at rest, position the programming head and select
[
PROGRAM
]. Wait for programming confirmed message.
3. Lift the programming head away from the site of the pacemaker to start
the test countdown. The screen will indicate the time remaining and a
tone will sound every 5 seconds.
The patient must remain at rest and not move during the 25-second
countdown. If the patient moves during this period, select [
RESTART
TEST
] and return to step 2.
Except to restart the countdown, do not reposition the programming
head until you are prompted to at the end of the 25-second countdown.
4. At the end of the countdown and as prompted by the screen, position
the programming head and select [
INTERROGATE
]. The interrogation
process will take several seconds.
Successful interrogation results in the Activity Test results screen
