Multicenter validation of an artificial intelligence–enabled electrocardiogram (ECG) model to predict 1-year risk of atrial fibrillation or flutter

Heart RhythmPublished retrospective study

Authors' conclusion

The results validate the performance of the Tempus ECG-AF model and support its clinical use for AF risk stratification.

Study context

Population
Patients aged 65+ years with no previous atrial fibrillation (AF) or history of pacer/defibrillator use240 (6.0%) developing AF within 1 year
Participants
4,017 patients
Exposure
Sensitivity and specificity of a risk score from an ECG-AI model evaluated against prespecified minimum values of 20% and 85%, respectively
  • increased riskn = 391
  • no increased riskn = 3,626
Methodological details3 clinical sites, external validation
  • 3 clinical sites
