ELECTROCARDIOGRAM-BASED DIAGNOSIS MODEL LEARNING DEVICE, ELECTROCARDIOGRAM-BASED DIAGNOSIS MODEL LEARNING METHOD, AND STORAGE MEDIUM

A learning device 1 X mainly includes a first acquisition means 31 X, a second acquisition means 32 X, and a learning means 34 X. The first acquisition means 31 X acquires a partial waveform of electrocardiogram data regarding an electrocardiogram of a subject. The second acquisition means 32 X acquires an attention interval, which is used as a basis for a diagnosis of a target disease, in a sequential waveform of the electrocardiogram data. The learning means 34 X trains a model configured to diagnose the target disease, based on the partial waveform and the attention interval.
