Q-TECH™ PROGRAMMER: OPERATiOn
The following functions occur during the test:
•
•
The S-ICD System induces ventricular fibrillation using 200 mA alternating current
(AC) at 50 Hz. Induction continues until the Hold To Induce button is released (up to
a maximum of 10 seconds per attempt).
Note: If necessary, the induction can be terminated by disconnecting the
wand from the programmer.
•
Arrhythmia detection and the Live S-ECG are suspended during AC induction. Once
the Induction button is released, the programmer displays the patient’s rhythm.
•
Upon detection and confirmation of an induced arrhythmia, the S-ICD System
automatically delivers a shock at the programmed energy output and polarity.
Note: Whenever the programmer is in active communication with an SQ-RX
device, charging of the pulse generator in preparation for delivering a
shock (whether commanded or in response to a detected arrhythmia)
is indicated by an audible notification. The notification continues until
the shock is delivered or aborted.
•
If the shock fails to convert the arrhythmia, re-detection occurs and subsequent
shocks are delivered at the SQ-RX device’s maximum energy output (80 J).
Note: Following the release of the Hold To Induce button, evaluate the
sensing markers during the induced rhythm. The S-ICD System uses
a lengthened rhythm detection period. Consistent tachy “T” markers
indicate that tachyarrhythmia detection is occurring, and that
capacitor charging is imminent. If a high degree of amplitude variation
is noted during the arrhythmia, a slight delay may be expected prior to
capacitor charging or shock delivery.
Note: The SQ-RX device can deliver a maximum of five shocks per episode. At
any time, an 80 J rescue shock can be delivered by pressing the Rescue
Shock icon.

At any time prior to therapy delivery, the programmed energy may be aborted by
selecting the red Abort button.
