13. DEVICE DESCRIPTION
The PARADYM RF CRT-D system includes the model 9750 ICD device
and programming system. The programming system includes the Sorin
CRM Orchestra Plus programmer with the SMARTVIEW programming
software connected to a CPR3 programming head. The programming
system is configured and furnished by Sorin CRM.
The PARADYM RF CRT-D 9750 can serves as a defibrillation
electrode (active housing) with a total surface area of 76 cm².
The PARADYM RF CRT-D 9750 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 CRT-D 9750 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 CRT-D
9750 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 CRT-D 9750 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.
