False Classification of FaST and non-FaST using DL Model. (A) False negative classification of FaST using DL due to low-amplitude, sustained periodic unipolar QS complexes near PV ostium (Patient 1, top panel) and broad, slurred unipolar QS complexes (Patient 2, bottom panel). (B) False positive classification of FaST using DL due to sustained unipolar rS complexes with small r waves (Patient 3, top panel) and near-sustained periodic unipolar QS complexes (red stars – rS complexes) (Patient 4, bottom panel).
