16. MAIN FUNCTIONS
16.1. AUTOMATIC LEAD MEASUREMENTS
Automatic pacing lead impedance measurement: A lead
impedance measurement is automatically performed on the lead
every 6 hours. The daily mean impedance is stored.
Automatic coil impedance measurement: A coil impedance
measurement is automatically performed on RV and SVC coils once
a week. The result is stored in the device memory.
16.2. VENTRICULAR TACHYARRHYTHMIA
MANAGEMENT
Searching for a long cycle (Stability+): Additional arrhythmia
classification criterion to improve identification of atrial fibrillation and
avoid inappropriate shocks.
Fast VT treatment: Applies detection criteria on fast ventricular
tachycardiathat are different from those of the VT zone, as well as
different therapies. The fast VT zone is included in the VF zone: its
lower limit is determined by the programmed value for the VF zone
and its upper limit by the programmed value for the fast VT zone.
Polarity alternation on Max:shock Reverses the programmed polarity
of every second shock set at maximum energy. The number, type, and
energy of shocks is independently programmable by detection zone.
16.3. PACING
BTO (Brady Tachy Overlap): Allows pacing in the slow VT zone,
without affecting detection specificity.
Post-shock mode: After any automatic shock therapy, the post-
shock mode makes it possible to apply different pacing parameters.
