A new dual-chamber wireless pacemaker is showing reliable performance, achieving nearly 98% synchronization between heart chambers, according to a study published in Circulation. Co-led by Dr. James Ip of Weill Cornell Medicine, the trial evaluated the pacemaker’s effectiveness over three months in 384 patients. The device maintained performance even during various activities and elevated heart rates.
Unlike traditional pacemakers that use leads, this device is wire-free, reducing risks like infection and wire breakage. “The wire is the Achilles’ heel of the pacemaker,” Ip said. The wireless pacemaker, approved by the FDA last year, offers a less invasive alternative for patients with complex heart rhythm issues.
Despite some limitations, such as smaller battery life, Dr. Ip is optimistic about future improvements. “We are not limited to the wired devices we’ve been using for more than 60 years,” he said, emphasizing the technology’s potential to revolutionize cardiac care.
