2.9.18 Post Shock Pacing
Separately programmable bradycardia pacing support is available
with the ICD/CRT-D following shock therapy delivery. Because a
delay in bradycardia pacing may avoid re-initiation of a
tachyarrhythmia, after a short blanking period (1 second), the
ICD/CRT-D will begin in standard program DDI bradycardia
therapy at the post shock pacing rate, amplitude (fixed to 7.5 V for
RV and as permanent programmed for LV) , and pulse width
(fixed to 1.5 ms) for the programmed
Post-Shock Duration .
Separate post shock programming of the following parameters is
available:
•
Ventricular Pacing Configuration (RV, BiV)
•
Basic Rate
•
Rate Hysteresis
•
AV Delay
•
Post Shock Duration
If bradycardia pacing is still required after the post shock duration
expires, standard bradycardia pacing parameters are active.
2.10 EP Test Functions
Several EP test functions are available with the Lumax family of
ICD/CRT-Ds including; P and R-wave amplitude, pacing and
shock impedances, retrograde conduction and pacing threshold
measurements. Extensive testing of defibrillation thresholds as
well as the ability to verify the effectiveness of anti-tachycardia
pacing and defibrillation shocks are also available.
2.10.1 P and R-wave Amplitude Measurements
The Lumax ICDs/CRT-Ds provide a P-/R-wave test for measuring
the amplitude of intrinsic events during follow-up examination.
The test determines the amplitudes with a predetermined
temporary pacing mode.
