AF Alert Management*

Focus on actionnable AF events

Atrial arrhythmia alerts: the major alert burden for remote monitoring teams

Atrial arrhythmias are one of the most commonly occurring alerts in remote cardiac monitoring. However, not all alerts related to atrial burden trends may be clinically relevant, as they may correspond to a known and treated condition and fail to highlight changes requiring attention. For a medical center following 1,000 patients, spending 2 minutes to review each alert would total 32 hours per month!

Our solution

AF Alert Management

A new algorithm tackling alert noise from atrial arrhythmia

Focus on the major stages in the AF trend of the patient

  • Reduce the atrial burden alerts
  • Identify the significant changes in the atrial burden history of the patient


Decrease the number of alerts with AF Alert Management

A retrospective study analyzed real-life data from more than 4,000 recipients of Abbott, Biotronik, Boston Scientific, or Medtronic CIED who were being continuously monitored for AF. Implicity compared the incidence of standard CIED-transmitted alerts from device manufacturers with the incidence of events detected after filtering by Implicity’s algorithm. Results showed the algorithm broke down 67,883 AF burden-related alerts into 9,728 (14.3%) clinically relevant AF events, according to the European Society of Cardiology classification. Notably, the median number of alerts per patient year decreased by 57.9%.

How Does It Work?

A CE-marked algorithm that analyzes:

  • Device data, such as atrial burden raw data
  • Clinical data, such as anticoagulant medications

The algorithm has two actions:

  • Filters out noisy and irrelevant manufacturers “atrial burden above threshold” alerts, during the period when patients take anticoagulants
  • Triggers smart alerts notifying of any significant changes in AF care

It can help identify the following scenarios based on ESC recommendations:

  • Consider proposing therapies to the patient, such as ablation (Paroxysmal AF, increasing paroxysmal AF, persistent AF)
  • Assess the success of therapies (Back to sinus rhythm or paroxysmal AF)

A smart follow-up of the AF burden trend

The current AF status of the patient is displayed, including dates and details.

The full history of the patient’s AF statuses is synchronised with the AF burden trend graph.

A simple display on the Implicity platform

The Implicity logo appears before each Smart Alert

  • Manufacturer alerts are automatically archived – as the patient is taking anticoagulants, and only appears in the timeline.
  • The timeline will display the Implicity logo to indicate Smart Alerts that the AF Alert Management algorithm has triggered.
