AF Management Guideline Aligned

AF Alert Management: focus on the AF alerts that need your attention.

Implicity analyzes the atrial burden behind each alert, moves repeat alerts to the patient timeline, where they remain available for review, and raises a Smart Alert when a patient’s AF pattern changes. In a retrospective study of more than 4,000 patients, median AF alerts per patient-year fell by 57.9%.2

Atrial fibrillation alerts

AF alerts fill the queue. Few of them change the plan.

Atrial burden alerts are among the most common in CIED remote monitoring. Device thresholds are triggered by the number, without the context of each patient’s history. In a retrospective study, 67,883 AF burden alerts corresponded to 9,728 clinically relevant AF events (14.3%) under the ESC classification.2

Redundant

The patient is already anticoagulated.

A threshold alert asks a question your team has already answered. It still has to be opened, read and closed.

Repetitive

The same AF, on every transmission.

Burden stays above threshold, so the alert keeps coming back, even when nothing about the patient’s AF has moved.

Buried

The real change looks like all the others.

When paroxysmal AF turns persistent, the alert reads much like the fortieth threshold alert before it.

~32 hours a month of AF alert review for a clinic following 1,000 patients, at two minutes per alert.3 Most of it goes to alerts not classified as clinically relevant.

How it works

From atrial burden to the alert that matters.

The algorithm looks at the device data and the clinical context together, then prioritizes what reaches your queue. Other alerts remain available in the patient timeline.

Inside the workflow

Every Smart Alert arrives with the trend behind it.

Six AF scenarios can trigger a Smart Alert. Pick one to see what reaches your team, and what moves to the timeline.

  • Your team sets the rules. Turn AF alert management on, choose whether manufacturer alerts are filtered, and choose whether Smart Alerts are triggered.
  • Nothing disappears. Archived manufacturer alerts stay on the patient timeline, one click away.
  • Context on one screen. The patient summary shows the current AF status with dates, synced with the burden trend graph.
  • Easy to tell apart. Smart Alerts carry the Implicity mark, so the team knows where each one came from.

Devices in the study

An AF alert should tell you something has changed. When it doesn’t, it adds to the review workload. Implicity keeps the changes in front of you and moves the rest to the timeline, where they remain available for review.

FAQ

Questions clinics ask us most.

Does AF Alert Management delete manufacturer alerts?

No. Manufacturer AF burden alerts for anticoagulated patients are archived to the patient timeline instead of the review queue. They stay in the record and can be opened at any time.

How does it know whether a patient is anticoagulated?

It uses the anticoagulant medications recorded in the patient’s clinical data on the Implicity platform, alongside the raw atrial burden data from the device.

Which changes trigger a Smart Alert?

Six scenarios: a first recorded AT/AF episode, paroxysmal AF, increasing paroxysmal AF, persistent AF, the end of persistent AF with a return to paroxysmal AF, and the end of persistent AF with a return to sinus rhythm.

Can we choose what gets filtered?

Yes. Your team can turn AF alert management on or off, choose whether manufacturer alerts are filtered, and choose whether Smart Alerts are triggered.

Which devices does it work with?

The published evaluation included CIED patients under continuous AF monitoring with Abbott, Biotronik, Boston Scientific and Medtronic devices. Request a demo and we’ll confirm the fit for your device mix.

Does it replace clinical judgment?

No. Smart Alerts are advisory and are meant to be used alongside physician judgment. They are not a sole means of diagnosis.

It is designed to optimize data workflows and support medical expertise in patient management. Smart Alerts are advisory and do not replace clinician review of device data.
