Abstract: An electrocardiogram analyzing apparatus has: an acquiring section acquiring a plurality of electrocardiogram waveforms; a classifying section classifying the plurality of electrocardiogram waveforms into a plurality of groups on a basis of shape similarity; an accepting section accepting a reference position of a predetermined type of wave designated on a representative waveform corresponding to at least one electrocardiogram waveform belonging to a selection group selected from the plurality of groups; and an analyzing section identifying correspondence between a plurality of positions, along a time axis, on the representative waveform of a group to which a subject-of-analysis electrocardiogram waveform belongs, and a plurality of positions on the subject-of-analysis electrocardiogram waveform along a time axis, and decides, as a position of the predetermined type of wave included in the subject-of-analysis electrocardiogram waveform, a position on the subject-of-analysis electrocardiogram waveform correspo

Abstract: A display control apparatus includes an acquisition part that acquires a value indicating the electric activity of the heart of a person to be analyzed, and a display control part that causes a display part to display a plurality of points corresponding to a plurality of values measured in a target period, wherein a distance between the predetermined reference point and each of the plurality of points corresponds to the value corresponding to the point, and a direction of a vector from the reference point to each of the plurality of points rotates clockwise or counterclockwise about the reference point in the order of times at which the plurality of values are measured.

Abstract: A data processing method including the computer-implemented steps of: acquiring one or more pieces of fibrillation wave electrocardiogram data including fibrillation waves included in whole electrocardiogram data obtained by measuring change over time of an action potential due to electric activity of a heart muscle; inputting the one or more pieces of fibrillation wave electrocardiogram data into a first machine learning model that classifies a plurality of pieces of electrocardiogram data including the fibrillation waves into electrocardiogram data in which the fibrillation waves are clear and electrocardiogram data in which the fibrillation waves are unclear, and acquiring clear electrocardiogram data output from the first machine learning model as the electrocardiogram data in which the fibrillation waves are clear; and outputting the clear electrocardiogram data.

Abstract: An electrocardiogram analysis apparatus includes a machine learning part that has a machine learning model realized by machine learning that uses training electrocardiogram data of a patient with paroxysmal arrhythmia during a non-paroxysmal period during which no episode of paroxysmal arrhythmia occurs; an input processing part that inputs electrocardiogram data of a person to be analyzed, which is a subject of analysis, into the machine learning model; and an output control part that outputs, to an information terminal, abnormality information which is to be output from the machine learning model and is about whether the person to be analyzed has paroxysmal arrhythmia.

Abstract: An electrocardiogram display apparatus includes an input processing part that inputs divided electrocardiogram data, which is obtained by dividing whole electrocardiogram data of a patient that has been measured over a predetermined time period into electrocardiogram data having a predetermined time length shorter than the predetermined time period, into a machine learning model realized by machine learning that uses a plurality of pieces of training electrocardiogram data each having the predetermined time length; a result acquisition part that acquires, from the machine learning model, a determination result indicating whether or not the divided electrocardiogram data includes a waveform portion suspected of indicating heart disease; and a display controlling part that causes a display apparatus to display information based on the determination result.

Abstract: A metal heat treatment method includes quenching a workpiece by blowing an inert gas onto the workpiece, adjusting the temperature of the inert gas to approximately an isothermal holding temperature of the workpiece for transformation of the workpiece, holding the isothermal holding temperature within a margin of error of approximately plus or minus five degrees Celsius for a given period, and performing a metal heat treatment with the isothermal holding temperature kept statically or dynamically by varying the temperature of the hot-gas.
