What a great summary of our recent Nature paper in 2 mins!
EchoNext, a DL ECG model trained on 1.2M ECG–echo pairs, prospectively identified previously undiagnosed SHD (PPV>50%) and exceeded cardiologist performance across 11 hospitals. Public weights + 100k-labeled ECG set released. doi.org/10.1038/s41586-025-0… #AIinMedicine #CardioTwitter #Cardiology #CardioTwitter #MedEd #DigitalHealth @Nature @NaturePortfolio @David_Ouyang @PierreEliasMD
