Heart RhythmPublished

  • development and validation of a deep learning model
  • 5-fold cross-validation
  • external cohort

Authors' conclusion

EFFNet significantly improves ECG-based LVH detection and introduces a novel deep learning framework for LVH risk prediction, advancing intelligent ECG-based screening and early identification of LVH.

Study context

Population
Individuals with 12-lead electrocardiogram (ECG) signals in the UK Biobank data set and the Qinghai data setUK Biobank data set 38,289 · Qinghai data set 142,777
Comparison
EFFNet left ventricular hypertrophy (LVH) classification against cardiovascular magnetic resonance measurement (UK Biobank) and echocardiography (Qinghai) as the reference standard

Association of EFFNet-predicted LVH with cardiovascular rhythm abnormalities

EFFNet-predicted LVH was associated with atrial fibrillation, ventricular premature beats, and atrial premature beats
