Machine learning of 12-lead Electrocardiograms Identified Inherited Risk
and Vulnerability to Atrial Fibrillation
Author(s): Avtar Singh*
Artificial intelligence (AI) models applied to 12-lead ECG waveforms can predict atrial fibrillation (AF), a hereditary
and pathological arrhythmia. We hypothesized that the ECGAI-based risk estimation may have a genetic basis. We
applied the ECGAI model to predict atrial fibrillation in ECGs from 39,986 UK bio bank participants without
atrial fibrillation. Next, we performed a Genome-Wide Association Study (GWAS) of predicted atrial fibrillation
risk. Three signals (P <5E8) were identified at the established AF sensitivity loci marked by the sarcomere gene
TTN and the sodium channel genes SCN5A and SCN10A. We also identified two new loci near the VGLL2 and
EXT1 genes. In contrast, GWAS of risk estimation from clinical variable models revealed different genetic profiles.
The predicted AF risk from the EKGAI model is affected by sarcomere, ion channels, and gene.. View more»
