2.10.6 Arrhythmia Induction Features
The ICD/CRT-D offers three arrhythmia induction methods for
non-invasive EP testing. These include the following:
WARNING
Resuscitation Availability - Do not perform induction testing
unless an alternate source of patient defibrillation such as an
external defibrillator is readily available. In order to implant
the ICD/CRT-D system, it is necessary to induce and convert
the patient’s ventricular tachyarrhythmias.
CAUTION
Manual Shocks – User-commanded shocks may be withheld
if the ICD/CRT-D is already busy processing a manual
command or the Battery Status is low.
HF Burst Induction consists of a large number of pulses
delivered in rapid succession over a period of several seconds.
The frequency of the pulses and the duration of the burst are
defined by the user.
Burst + PES (Lumax 300/340 & 500/540 models only) Induction
delivers a programmed number of pacing stimuli followed by a
programmable number (Number S1) of timed extra stimuli. The
burst rate (intervals) is independently programmable, as is the
chamber being stimulated (RV, LV or BiV). The interval between
S1s and the remaining programmed extra stimuli (PES: S1
through S4 possible) are also programmable.
Shock on T induction mode allows tachyarrhythmia induction by
means of a timed T wave shock delivered after a series of paced
stimuli. Energy of the T wave shock, number of pulses
(Number S1) in the pulse train, synchronization interval (R-S1)
and the shock Coupling interval are all programmable.
