Rather than a single transvenous electrode, a dual-chamber pacing system incorporates two electrodes which sense and pace the right atrium and ventricle respectively mimicking the natural sequence of chamber contraction.
What is known is that, at least initially, only patients who require pacing in one chamber of the heart will be candidates for the leadless pacemakers--many patients needing pacemakers today require dual-chamber pacing.
The David Trial demonstrated that for patients with standard indications forICD therapy, no indication for cardiac pacing, and an LVEF of40% or less, dual-chamber pacing offers no clinical advantageover ventricular backup pacing and may be detrimental by increasingthe combined end point of death or hospitalization for heartfailure.
Wilkoff adds that many patients needing pacemakers today require dual-chamber pacing and defibrillation, which are not available through the new leadless pacemakers.
