ATRIAL FIBRILLATION MANAGEMENT CARDIAC DIAGNOSTICS & MONITORING

Ongoing cardiac monitoring for the management of atrial fibrillation
Alert Important Safety Information

MONITORING PATIENTS

Patients with asymptomatic episodes are at equal risk for stroke as symptomatic patients.1

  • 69% of patients had at least one AF recurrence2
  • 56% of the recurrent AF being asymptomatic*3
  • 3X increase in asymptomatic episodes post-ablation3

HRS AF Ablation Guidelines

  • Prior to undergoing a catheter ablation procedure, it is important to confirm that a patient’s symptoms result from AF and to determine whether a patient has paroxysmal or persistent AF. This is of importance as the ablation technique, procedure outcome, and anticoagulation strategies employed … may be impacted by the accurate characterization of the AF type and burden.4
  • Patients in whom discontinuation of systemic anticoagulation is being considered should consider undergoing continuous ECG monitoring to screen for asymptomatic AF/AFL/AT.5

Cardiac Monitoring for your AF Patients

Continuous cardiac monitoring leads to more actionable events than conventional monitoring.6

Build a diagnostic picture by continuously monitoring AF burden, heart rate variability, and daily activity with Reveal LINQ™ insertable cardiac monitor (ICM).

Reveal LINQ ICM provides physicians with longitudinal data to objectively determine both asymptomatic and symptomatic AF. This data results in the measure of true AF burden and accurate characterization of the AF type to effectively guide therapy decisions.3,7

data-driven decisions

  1. AT/AF total time per day 
    This trend data is based on a count of 2-minute periods when an AT/AF episode is detected or in progress.
  2. Ventricular rate during AT/AF
    The daily average ventricular rate is derived from the number of ventricular beats during AT/AF episodes and the total time in AT/AF for that day.
  3. Average ventricular rate
    The average day and night heart rates are derived from the sum and number of R-R intervals during the periods defined as “day” and “night.”
  4. Patient activity
    The sum of patient activity in hours per day.

  5. Heart rate variability 
    Median ventricular interval calculated every 5 minutes.
