SENSE Clinical Trial

Subclinical atrial fibrillation detection with a floating atrial sensing dipole in single lead implantable cardioverter defibrillator systems: Results of the SENSE trial

doi: 10.1111/JCE.14081

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

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 Details

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
