99.9%1 intrinsic conduction

 

 


Intelligent Management of AV Conduction

 

  • Ensures DDD pacing when needed for ALL types of AV block

  • Provides AAI pacing while continuously monitoring AV conduction

  • Switch back to AAI mode when possible


 

 

    Manages all AV Block

  • AVB I : 7 long PR intervals -> DDD

  • AVB II : 3 blocked P waves / 12 -> DDD

  • AVB III : 2 consecutive blocked P waves -> DDD



    Manages Rest and Exercise

  • AVB I criteria can be suppressed at rest

  • Rapid switch to DDD during exercise if required



    Manages Day and Night

  • Reduces nocturnal pacing by allowing long PR

  • Tests for AV conduction each morning if in DDD
