It’s the same size and shape as the original Micra system approved in 2016, but it has several additional internal atrial sensing algorithms that detect cardiac movement.
The Micra AV is able to adjust pacing in the ventricle to coordinate with the atrium, enabling it to provide “AV synchronous” pacing therapy to people with atrioventricular block. People with AV block have previously needed a dual-chamber pacemaker, even though only one of the two leads in the system provided heart stimulation.
