Pacing Functions
Pacing is initiated and controlled by pressing front panel keys. These key
presses are transferred from the keys to the Interface PCA via a flex circuit.
The key presses are detected and processed by the Interface PCA and then
passed to the Control PCA via a large ribbon cable.
The Control PCA directs the Power PCA to deliver the pacing pulses at the
rate and with the output selected by the user. The pacing pulses are delivered
via the pads cable to the defibrillation pads. The pacing current delivered is
reported back to the Control PCA, which sends the info to the display and
activates any printouts or screen messages as needed.
