2.8.3.6 Third Programmable Shock Pathway
Lumax 500/540 Models only
The Lumax 500/540 models offer three programmable shock
delivery configurations. The defibrillation shock pathways include
a “non-active housing” shock path and a shock paths between the
ICD/CRT-D housing and either or both shock coils when
connected to a dual coil shock lead.
The Shock Configuration parameter operates independently of
Shock Polarity. So each of the pathways described below can be
reversed for delivered defibrillation/cardioversion shocks.
Table 24 outlines the current shock pathways that are available
with Lumax 500/540 models.

2.8.4 Progressive Course of Therapy
By design, the Lumax ICDs/CRT-Ds will deliver more aggressive
therapy for each successive attempt within a single detected
episode. Therefore, the device will not deliver ATP1 therapy
following ATP2 therapy, and will not deliver ATP therapy following
a high voltage defibrillation shock.
When Progressive Course of Therapy is turned ON, the ICD/CRT-
D will always deliver a maximum energy shock after re-detecting
in an arrhythmia class with programmed shock energy less than
or equal to the previously delivered therapy. In addition, the
ICD/CRT-D blocks all ATP therapy during the current episode if a
shock has already been delivered during the episode.
