INFORMATION FOR USE
DEVICE DESCRIPTION
Sensing
• Sensing is designed to combine the strengths of both implantable
cardioverter defibrillator (ICD ) and pacemaker sensing capabilities to
improve detection and therapy by reducing inappropriate mode switching,
pacing inhibition, and shocks.
DEVICE DESCRIPTION
This manual contains information about the C OGNIS 100 family of cardiac
resynchronization therapy defibrillators (CRT-Ds) (specifi c models are listed in
"Mechanical Specifications" on page 1-21).
Therapies
This family of pulse generators has a small, thin, physiologic shape that
minimizes pocket size and may minimize device migration. Pulse generators
within this family provide a variety of therapies, including:
• Ventricular tachyarrhy thmia therapy, whic h is used to treat rhythms
associated with sudden cardiac death (SCD) such as VT and VF
• Cardiac Re synchronization Therapy (CRT), which treats heart fa ilu re by
resynchronizing ventricular contractions through biventricular electrical
stimulation
• Bradycardia pacing, including adaptive rate pacing, to detect and treat
bradyarrhythm ias and to provide cardiac ra te support after defib r illation
therapy
Cardioversion/defibrillation therapies include:
• A range of low- and high-energy shocks using a biphasic waveform
• The choice of multiple shock vectors:
– Distal shock electrode to proximal shock electrode and pulse generator
case (TRIAD electrode sys tem )
– Distal shock electrode to proximal shock electrode (RV Coil to RA Coil)
– Distal shock electrode to pulse generator case (RV Coil to Can)
