PACING T HERAPIES
BASIC PARAMETERS
5-3
Post-Therapy Settings include the following:
• Pacing parameters, which are independently programmable from normal
and temporary pacing parameters
• Post-ventricular shock
Brady Mode
Brady modes provide you with programmable options to help individualize
patient therapy.
This pulse generator includes the pacing modes identified in the Programmable
Options appendix.
Dual-Chamber Modes
Do not use DDD(R) and VDD(R) modes in the following situations:
• In patients w ith chronic re fra ctory atrial tachyarrhythmias (atrial fibrillation
or flutter), which may trigger ventricular pacing
• In the presence of slow retrograde conduction that induces PMT, which
cannot be controlled by reprogramming selective parameter values
Atrial Pacing Modes
In DDD(R), DDI(R), and AAI(R) modes, atrial pacing may be ineffective in
the presence of chronic atrial fibrillation or flutter or in an atrium that does
not respond to electrical stimulation. In addition, the presence of clinically
significant conduction disturbances may contraindicate the use of atrial pacing.
WARNING: Do not use atrial tracking modes in patients with chronic refractory
atrial tachyarrhythmias. Tracking of atrial arrhythmias could result in VT or VF.
NOTE: If a separate pacemaker is desired, a dedicated bipolar pacemaker
is recommended.
NOTE: Refer to "Use of Atrial Information" on page 3-5 for additional
information about device performance when the atrial lead is programmed to
Off.
