New Delhi, October 6, 2025 – Global healthcare leader Abbott has announced the launch of the AVEIR™ dual chamber (DR) leadless pacemaker system in India — marking a major medical milestone as the world’s first leadless pacemaker capable of pacing both chambers of the heart.

Pacemakers are life-saving devices that help manage bradycardia, a condition where the heart beats too slowly. Traditional systems rely on wires (leads) and surgical pockets to regulate the heartbeat. In contrast, leadless pacemakers are miniature, self-contained devices that are implanted directly into the heart using a catheter, eliminating the need for wires and reducing complications.

Until now, leadless technology was limited to single-chamber pacing, but Abbott’s AVEIR DR system changes that with its implant-to-implant (i2i) communication technology. This allows two tiny devices—one in the atrium and one in the ventricle—to communicate beat-by-beat in real time, achieving synchronised, dual-chamber pacing for the first time ever without wires.

This innovation is particularly relevant for India, where approximately one in three pacemaker patients require dual-chamber pacing.

“As leadless pacing technology has evolved, we’ve built upon our AVEIR VR single-chamber platform to expand the benefits to far more people,” said Ajay Singh Chauhan, General Manager for Abbott’s cardiac rhythm management business in India, Southeast Asia, Hong Kong, Taiwan, and Korea. “This tiny device packed with powerful technology is designed to treat abnormal heart rhythms more precisely and effectively.”
