EGM
EGMs (intracardiac electrograms) show the sensed electrical activity of the heart. The shape and size of
the waveform depend on the available
The configurations available are Unfiltered or Sense Amp (narrow band filtered data). The Sense Amp
filtering characteristics of the Merlin PSA are designed to match those of St. Jude Medical™ pulse
generators. The default configuration is Unfiltered, and once it’s changed, the new configuration is
saved for future sessions.
Select the
button to select the waveform source and configuration, and also the sweep
speed and the ECG Filter.
Current of Injury
The Current of Injury view shows an unfiltered view of the EGM and an amplitude value measured
from peak-to-peak of the waveform. (The filtered EGM view measures the Sense Amp waveform from
baseline-to-peak.) The peak-to-peak amplitude of the unfiltered EGM is shown in the upper left corner
of the Current of Injury view. The Current of Injury view updates with every sensed beat.
Use the Plus (+) and Minus (-) buttons to manually set the gain. AutoGain is not available in the
Current of Injury view.
Select the Current of Injury button to return to the Rhythm Display.
