Study Design

  • Prospective, multicenter cohort-controlled study

  • 150 patients implanted with a BIOTRONIK DX ICD system, comparing data with historical single- and dual-chamber ICD cohorts derived from previous studies

  • 8 US centers

  • To determine the utility of the DX implantable cardioverter-defibrillator (ICD) system for subclinical atrial fibrillation (AF) detection

Key Result 1


Key Result 2


Clinical Relevance

  • First study to assess efficacy of DX technology for subclinical AF detection in a prospective, multicenter, cohort-controlled trial.

  • The results indicate that the DX ICD system may offer significant benefits for AHRE detection in ICD patients who do not have an atrial pacing indication, but are at high risk of developing subclinical AF


Study Objective
  • To determine the utility of the DX implantable cardioverter-defibrillator (ICD) system for subclinical atrial fibrillation (AF) detection
Primary Endpoint
  • Atrial high rate episode > 30 seconds in duration
Major Secondary Endpoints
  • P wave amplitudes measured by DX lead system
  • Detection of AHRE > 6 minutes duration by DX lead system
Clinical Sites
  • 8 US centers
Sample Size
  • 450 participants
Main Inclusion Criteria
