Intrinsic Amplitude Test
The intrinsic amplitude test m easures the intrinsic P- and R-wav e a mplitudes
for the respective cham bers.
An intrinsic amplitude test can be performed from the Lead Tests screen by
completin g th e following steps:
1. You may change the following preselected values as necessary to elicit
intrinsic activity in the chamber(s) being tested:
• Programmed Normal Brady Mode
• LRL at 30 ppm
• AV Delay at 300 ms
2. Sele ct the Intrinsic Amplitude button. During the test, a window will display
the test’s progress. Selecting a nd holding th e Intrinsic Amplitude Button will
cause measurements to be repeated for up to 10 seconds until the button is
released. When the window closes, the same test can be performed again
by selecting the In trinsic Am plit ude button. To cancel th e test, select the
Cancel button or press the DIVERT THERAPY key on the PRM.
3. When the test is complete, the intrinsic amplitude measurement will be
displayed. If the test is repeated, the measurements from the previous
session’s test and the current test will be displayed.
NOTE: The test results from the last measurement are stored in pulse
generator memory, retrieved during the initial interrogation, and displayed on
the Lead Tests screen. The measurements are also provided on the Quick
Notes report.
