    Indication Statement

    HeartBug is for the investigation of: (i) episodes of suspected intermittent cardiac arrhythmia or episodes of syncope; or (ii) suspected intermittent cardiac arrhythmia in a patient who has had a previous cerebrovascular accident, is at risk of cerebrovascular accident or has had one or more previous transient ischemic attacks.

      International Guidelines — Diagnosing Atrial Fibrillation

      Longer Monitoring = Higher AF Detection

      A monitoring time lasting 2 weeks or longer is preferable to maximise the possibility of identifying individuals with AF.

      The Evidence

      CRYSTAL AF

      Extended cardiac monitoring significantly increases AF detection in patients with cryptogenic stroke.

      01

      Cryptogenic stroke

      Stroke of undetermined source, where occult AF is the leading suspect.

      02

      Duration drives detection

      The longer the monitoring window, the higher the AF yield.

      03

      Anticoagulation

      Detected AF changes therapy — antiplatelet to anticoagulant.

      04

      Stroke prevention

      Earlier detection directly reduces recurrent stroke risk.
