A Dual-Chamber Leadless Pacemaker

his original research article evaluates the safety and performance of a dual-chamber leadless pacemaker system developed to address limitations of single-chamber devices. Involving 300 patients across multiple international centers, the study assessed implantation success and short-term outcomes. The system, composed of two wirelessly communicating leadless devices implanted in the right atrium and right ventricle, achieved a 98.3% implantation success rate and exceeded performance goals for atrial sensing, capture thresholds, and atrioventricular synchrony at 3 months. Complications were relatively low and manageable. The findings suggest this modular pacing system may be a viable alternative to conventional transvenous pacemakers for patients requiring dual-chamber pacing.
