Select and hold the Hold To Induce button for the desired duration (Figure 33).

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).
•
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.
•
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.
