Outcome Measures

Primary Outcomes (1)

  • Demonstrate that AT 500 algorithms decrease AF Burden

Secondary Outcomes (5)

  • Characterize the efficiency of prevention and termination algorithms on the Quality of Life of patients

  • Characterize the correlation between symptoms and stored EGM's

  • Determine the total number of AF/AT episodes and observe the decrement of their occurrence frequency due to prevention algorithms.

  • Determine the number of Hospitalization, physician visits…: economical analyze

  • Analyze the episode onset mechanism
