2.9.14 Post Ventricular Atrial Refractory Period
DR and HF versions only
Immediately following each paced ventricular event, an atrial
refractory period is started; this period is called Post Ventricular
Atrial Refractory Period or PVARP. Atrial signals are ignored
during this time for bradycardia timing purposes to prevent the
ICD/CRT-D from sensing inappropriate signals.
2.9.15 PVARP after VES
DR and HF versions only
This parameter extends the Post Ventricular Atrial Refractory
Period by the programmed interval, if the ventricular event is not
followed by an atrial sensed event (VES).
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 occur or the shortest value of these parameter will be
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 responds to detected noise is to deliver
asynchronous pacing in the affected channel.
