Reduce Unnecessary RV Pacing

MVP AAIR graphic

With updated MVP algorithm2

Now with the option to control maximum AV interval

  • MVP algorithm reduces unnecessary RV pacing by 99%.6
  • RV pacing is associated with a 1% increase in risk of AF for each 1% increase in RV pacing.7
  • RV Pacing is also associated with an increased risk of HF hospitalisation.7


Reduce The Progression To Permanent AF


With Reactive ATP algorithm

In the MINERVA trial,3 Reactive ATP algorithm demonstrates

  • 61% relative reduction for the progression to permanent AF
  • 42% relative reduction in AF-related hospitalisations and 68% relative reduction in ER visits4
  • 45% relative reduction for AF cardioversions5


Expanded MRI Access

Astra XT MRI SureScan pacing systems are approved for safe use in the MR environment, when MR conditions for use are met.  With Astra XT MRI, patients have access to 1.5T and 3T full body scanning.

  • Our SureScan devices and leads work in any combination.
  • Scanning conditions are simple; no MRI exclusion zone, no patient height restriction, no MRI duration restrictions.
