2.9.16 Auto PVARP
DR and HF versions only
This parameter automatically adjusts the Post Ventricular Atrial
Refractory Period (PVARP) and PVARP after VES, if a
pacemaker mediated tachycardia (PMT) has been detected and
terminated to avoid additional PMT events. After seven days,
PVARP and PVARP after VES are reduced as short as possible
until a new PMT occurs or the shortest value of these parameters
is reached. This helps to keep the PVARP and PVARP after VES
as short as possible to protect the patient from PMT.
2.9.17 Noise Response
The Lumax ICD/CRT-D’s response to detected noise is to deliver
asynchronous pacing in the affected channel.
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 in DR & HF type
devices and VVI in VR & DX type devices) 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
 Fixed AV Delay
 Post Shock Duration
If bradycardia pacing is still required after the post shock duration
expires, standard bradycardia pacing parameters are active.
