Title: Electrocardiogram diagnostic device based on machine learning using electrocardiogram images
Inventor: MORI HIROKI
IPC: A61B5/0452
Filed: 2019-06-25
Abstract: As a conventional example of an electrocardiogram diagnostic support method, methods have been proposed in which the learning stage is divided into two stages and a two-stage learning model is generated, but such models learn binary classification models that output 'normal' or 'abnormal' and output only whether the waveform of the ECG image indicates an abnormality, so do not determine an actual diagnosis (disease name, sickness name, etc.). In the present invention, an electrocardiogram diagnostic device is provided which uses training data comprising diagnoses ('normal', or multiple sickness names (disease names)) attached to electrocardiogram images to learn a model that, in addition to 'normal', can output disease names through machine learning such as CNN, LSTM, etc. By giving electrocardiogram images obtained in an actual test to a model that has been learned, the electrocardiogram diagnostic device outputs a diagnosis ('normal', or disease names) that can be obtained by reading the electrocardiogram image.
