'World's smallest pacemaker' gets FDA approval

The FDA approved Jan. 21 Medtronic's Micra AV, the world's smallest pacemaker with atrioventricular synchrony, according to the company. 

The device is designed to treat patients with AV block, a condition in which electrical signals between chambers of the heart are impaired. 

Atrioventricular synchrony means the device detects cardiac movement so it can adjust its pacing in the ventricle to coordinate with the atrium. 

Use of the Micra has shown a 63 percent decrease in major complications compared to traditional pacemakers, according to Larry Chinitz, MD, director of NYU Langone's heart rhythm center.
