2.8.3.4 Shock Energy
The Lumax ICDs/CRT-Ds are designed to charge to the energy
selected on the programmer screen, but similar to all other
commercially available ICDs/CRT-Ds, the actual therapy
delivered is somewhat less depending on several factors
including the shock lead impedance. The first two shock energies
in each therapy class are programmable between 1 joules for
Lumax 300/340 & 500/540 models and 2 joules for Lumax
600/640 & 700/740 models and the maximum energy for the
device type. The energy of the second shock is always greater
than the first shock. The remaining shock energies will be
delivered at maximum programmable energy.
Actual energy delivered for each programmable shock energy is
approximately equal to the “Energy Delivered” for the high energy
Lumax 340/540/640/740 variants in Table 30
, and for the Lumax
300/500/600/700 in Table 31
