13. DEVICE DESCRIPTION
The INTENSIA VR system includes the model 124 ICD device and programming system.
The programming system includes the Sorin dedicated programmer with the SMARTVIEW
programming software connected to a CPR3 programming head. The programming system
is configured and furnished by Sorin.
The INTENSIA VR 124 can serve as a defibrillation electrode (active housing) with a total
surface area of 76 cm².
The INTENSIA VR 124 is designed to recognize and treat slow or fast VT and VF by
continuously monitoring ventricular activity to identify persistent ventricular arrhythmias and
to deliver appropriate therapies. INTENSIA VR 124 features DISCRIMINATION algorithm,
which is specifically designed to differentiate ventricular tachycardias from fast rhythms of
supraventricular origin. DISCRIMINATION continuously monitors R-R interval stability,
searches for long cycles and evaluates sudden onset.
In addition to the advanced detection scheme, INTENSIA VR 124 offers programmable
single-chamber pacing therapy with or without rate-responsive capabilities using an
acceleration sensor.
INTENSIA VR 124 offers tiered therapy. Therapies can be programmed independently in
each zone:
─ in the Slow VT and VT zones: two ATP programs, up to two shocks with programmable
energy and up to four shocks with maximum energy can be programmed;
─ in the VF zone: one ATP program, up to two shocks with programmable energy and up
to four shocks with maximum energy can be programmed.
When the rhythm changes from one zone to another, the device delivers the therapy
programmed in this zone, starting with the same or more aggressive program for the area.
The ATP program in the VF zone will only be applied if the VT coupling interval is longer
than the programmed fast VT cycle length.
The INTENSIA VR 124 offers biphasic shocks with a maximum stored energy of 42 J. The
shock configuration (electrodes used to apply the shock) can be chosen by programming
one of the following combinations: can and one coil, can and two coils, two coils only.
Other features are as follows:
─ Automatic ventricular sensitivity control
─ Non-committed shocks
─ Electrophysiological studies (EPS) with real-time markers or electrograms:
─
Programmer-controlled VT induction sequences,
─ Programmer-controlled VF inductions (30 Hz rapid pacing or shock on T),
─ Programmable electrogram vectors ( EGM V, RVcoil-CAN, SVC-CAN, RVcoil-SVC),
─ Real-time annotations displayed with the markers and indicating the majority rhythm,
─ Manual ATP sequences,
─ Manual shocks.
─ Rescue shock
─
Follow-up tests:
─ Pacing lead impedance,
─ Coil impedance,
