Abstract
Hypertrophic cardiomyopathy (HCM) is frequently underdiagnosed. While deep learning (DL) models using raw electrocardiographic (ECG) voltage data can enhance detection, their use at the point-of-care is limited. Here we report the development and validation of a DL model that detects HCM from images of 12-lead ECGs across layouts. The model was developed using 124,553 ECGs from 66,987 individuals at the Yale New Haven Hospital (YNHH), with HCM features determined by concurrent imaging (cardiac magnetic resonance [CMR] or echocardiography). External validation included ECG images from MIMIC-IV, Amsterdam University Medical Center (AUMC), and UK Biobank, where HCM was defined by CMR (YNHH, MIMIC-IV, AUMC) and diagnosis codes (UK Biobank). The model demonstrated robust performance across image formats and sites (AUROCs: 0.95 internal testing; 0.94 MIMIC-IV; 0.92 AUMC; 0.91 UK Biobank). Discriminative features localized to anterior/lateral leads (V4-V5) regardless of layout. This approach enables scalable, image-based screening for HCM across clinical settings.

The low prevalence of individual structural heart diseases limits the potential implementation of models for broad screening because of the low PPVs of the proposed models.
“While these models provide a strong foundation for the role of ECG-based detection of SHDs, the low prevalence of these individual diseases, their potential implementation for broad screening is limited by the low PPVs of the proposed models.10-12,16,32-34”

The Discussion says community-based screening with this HCM model can produce high false-positive rates and that low prevalence limits screening yield. The Results report only 29 HCM cases among 45,389 UK Biobank ECGs. This supports the concern for HCM, but the paper does not establish low PPVs or screening limitations across multiple structural heart diseases and their proposed models. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
