Biotronik releases CRT pacemaker with advanced algorithm for RVsense
10 July 2008
Biotronik has released the Stratos LV cardiac resynchronization
therapy pacemaker (CRT-P) incorporating RVsense Triggering which helps
assure that resynchronization therapy is delivered continuously.
CRT devices are indicated for certain types of heart failure patients
and may improve the pumping action of the heart by helping to
synchronize the heart’s lower chambers (the ventricles).
Unlike conventional pacing, which should be delivered only on an
as-needed basis, CRT works best when used continuously. Previously,
device algorithms were based on the premise that the device should
preferentially be on stand-by, creating certain challenges for
uninterrupted therapy. Stratos LV now addresses this important topic.
RVsense Triggering helps maintain resynchronization by forcing the
pacemaker to pace the left ventricle whenever there is activity in the
right ventricle (whether it is a paced event or the heart beats on its
own). This assures that there will be no 'one-sided' cardiac activity,
and may help to preserve ventricular ejection fraction (a standard
measure of the heart’s ability to pump blood efficiently), reduce
symptoms of heart failure, and synchronize ventricular intrinsic
contraction within 2.5 ms of a sensed or paced event in the right
The Stratos LV also offers an expanded wideband IEGM Snapshot memory,
with 10.5 minutes of 3-channel IEGM storage, offering critical
information to diagnose or troubleshoot patient conditions.
Additionally, Biotronik’s Wideband IEGM Snapshots are some of the most
comprehensive diagnostic reports available.
“The heart failure patient population is large and continues to grow
as the general population ages. Heart failure patients are diverse and
their clinical and personal needs vary from patient to patient. There is
no ‘one-size-fits-all’ therapy. As we learn more about heart failure and
about device-based treatment, it is evident that CRT pacemakers remain
an important option for certain patient populations. Biotronik is
pleased to offer our customers a broad therapy portfolio that includes
the latest advances with these pacing devices,” saidd Thomas Brown,
Executive Vice President of US Sales and Marketing.
Heart failure is a debilitating syndrome characterized by progressive
weakening of the cardiac muscle and is frequently associated with a
dyssynchronous contraction pattern of the ventricles (lower chambers of
the heart), which can be treated with cardiac resynchronization therapy
(CRT). According to multiple large-scale randomized clinical trials,
this device-based treatment may decrease morbidity and mortality in
certain heart failure patients.
