The world’s smallest pacemaker, which is about as big as a large vitamin capsule and provides the most advanced pacing technology, has been successfully implanted in a patient in the US. The pacemaker is for patients with bradycardia, a condition characterised by a slow heart rate, usually fewer than 60 beats per minute. It is known as Micra Transcatheter Pacing System (TPS).

The Micra Transcatheter Pacing System (TPS), recently approved by the US Food and Drug Administration (FDA), is a new type of heart device that provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker and is the only leadless pacemaker approved for use in the US. 

The pacemaker is for patients with bradycardia, a condition characterised by a slow heart rate, usually fewer than 60 beats per minute. Patients with bradycardia have lower heart rate and their heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise, causing dizziness, shortness, fatigue of breath or fainting spells.
