The Leadless Pacemaker for Bradycardia
St. John's Regional Medical Center is proud to be among the first hospitals in the area to offer the world's smallest pacemaker to help treat patients with bradycardia.
Recently approved by the U.S. Food and Drug Administration, the Micra® Transcatheter Pacing System (TPS) is a new device that provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker. The miniaturized heart device is designed to provide the most advanced pacing technology-all while being cosmetically invisible. The leadless pacemaker, unlike traditional pacemakers, does not require cardiac wires (leads)
or a surgical "pocket" under the skin to deliver a pacing therapy.
What is Bradycardia?
Bradycardia is a condition characterized by a slow or irregular heart rhythm, usually fewer than 60 beats per minute. At this rate, the heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise, causing dizziness, fatigue, shortness of breath or fainting spells. Pacemakers are the most common way to treat bradycardia to help restore the heart's normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.
