The first prospective multicenter study of Micra AV concludes that it significantly improves quality of life in patients with AV block and normal sinus function.1
To report on the performance of the Micra AV leadless ventricular pacemaker with accelerometer-based algorithms that provide AV synchronous pacing.
Sustained resting AV synchrony
85.4% and stable through three months.
Improved ambulatory AV synchrony
82.6% with optimized programming.
No upgrades through three months
No major complications due to pacemaker syndrome.
Ambulatory AV synchronous pacing by sinus rate during a 24-hour period
Access interactive courses, videos, and educational resources to extend your learning on Micra.
