The PARADYM RF SonR CRT-D 9770 is designed to recognize and
treat slow or fast VT and VF by continuously monitoring atrial and
ventricular activity to identify persistent ventricular arrhythmias and to
deliver appropriate therapies. PARADYM RF SonR CRT-D 9770
features the PARAD/PARAD+ algorithm, which is specifically designed
to differentiate ventricular tachycardias from fast rhythms of
supraventricular origin. PARAD/PARAD+ continuously monitors R-R
interval stability, searches for long cycles, assesses the degree of P-R
association, evaluates sudden onset and determines the chamber of
arrhythmia acceleration.
In addition to the advanced detection scheme, PARADYM RF SonR CRT-
D 9770 offers programmable single, dual or triple-chamber pacing
therapy (DDD, DDI, VVI or SafeR modes) with or without rate-
responsive capabilities (DDDR, DDIR, VVIR, DDD/DDIR and SafeR-
R modes) using an acceleration sensor. An automatic AV delay
algorithm as well as a mode switching function are available.
PARADYM RF SonR CRT-D 9770 enables an adjustment of the
interventricular delay, and provides the possibility of adapting pacing to
each ventricle. The ICD is intended to resynchronize uncoordinated
contraction of the heart by simultaneously or sequentially pacing both
ventricles.
PARADYM RF SonR CRT-D 9770 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.
The ATP can be applied in RV, LV or RV and LV pacing with a VV
delay equal to 0 ms. ATP pacing configuration is independent of
ventricular pacing configuration.
