The major distinguishing feature of a biventricular pacemaker is the insertion of a left ventricular lead to accomplish ... an ICD at the same time. When atrial fibrillation is present, the ...

Background: In patients requiring permanent pacing, preservation of intrinsic ventricular activation is preferred whenever possible. The Search AV+ (SAV+) algorithm in Medtronic EnPulse™ dual ...

Wandering atrial pacemaker is similar to multifocal atrial ... at least three distinctly different P wave morphologies and a ventricular rate of less than 100 bpm.

When SAV+ is activated, the pacemaker ... atrial refractory period (AutoPVARP) and rate adaptive AV (RAAV) can shorten the AV intervals at higher rates and potentially lead to ventricular pacing.
