Choose desired waveform for the sensitivity test by pressing UP
(F2) or DOWN (F3) and then SELECT (F4) . Press CANCEL
(F5) to cancel selection.
8. SENS. TEST (Sensitivity Test) (F2). Sensitivity is the QRS
minimum amplitude (mV) required to cause the pacemaker to
operate in the demand mode. This waveform is delayed from
the pacer pulse so that it is outside the pacing refractory period.
See ‘Sensitivity Measurements’ in Chapter 5.
9. REF. PER TEST (F3). Used to test time interval (ms) if the
pacemaker is insensitive to any external inputs, the maximum
time interval after the generation of a pacer pulse and maximum
time interval after a QRS wave. See ‘Pacing Refractory Period’
and ‘Sensing Refractory Period’ in Chapter 5.
10. REMOTE (Remote Control) (F4) enables communication with
a PC with test automation software. Required software: PRO-
Soft QA-40/45.
3.5 Test Result Printouts
1. Defibrillator Mode. QA-45 automatically prints out the test re-
sults, via the printer output, after each discharge generated. Se-
