Cardiac stimulator 4427 Easypace - Instructions for use
24/40
9. OPERATING MODES
Described in the next chapter are the three modes - with relevant options - in which
the 4427 Easypace is able to operate.
9.1. STAND-BY mode
The STAND-BY mode is intended for setting stimulation and sense parameters
under no-stimulation condition. This is the operational configuration obtained upon
completion of the self-test procedure following the unit’s power-on.
Preset values are:
• frequency 72 ppm;
• current 10 mA;
• sense threshold 1 mV.
Afterwards, the mode may be used for the temporary breaking off of the stimulation
without loosing the parameter values being set.
9.2. V00 (A00), BURST x4 and DECREASING RAMP mode
V00 - This asynchronous stimulation function allows a pacing to be set independent
of the presence of a spontaneous activity, as shown in the figure below:

Stimulation
The stimulation is started by simply acting on the V00 key and is made to terminate by
pressing (for 1÷2 seconds) the STAND BY key. The stimulation is instead shifted to the
synchronous mode by pressing VVI.
The amplitude and rate of the stimuli can be modified at any moment without interrupting
the stimulation. The corrected value of the modified parameter is constantly indicated on
the display.
