  • Publication number: 20240164691
    Abstract: An electrocardiogram analysis assistance device (10) including: an analysis waveform acquisition unit (11C) that acquires waveform data in an electrocardiogram for analysis; an analysis waveform select and extract unit (11D) that selects and extracts waveform data of a predetermined first period from the waveform data acquired by the analysis waveform acquisition unit (11C) as analysis divided waveform data; an intermediate information acquisition unit (11I) that acquires intermediate information generated in a middle layer of a peak estimation model (13C) and indicating a shape feature of a peak contained in the analysis divided waveform data by inputting the analysis divided waveform data selected and extracted by the analysis waveform select and extract unit (11D) into the peak estimation model (13C); and a classification unit (11J) that classifies a type of the waveform of the electrocardiogram for analysis using the intermediate information acquired by the intermediate information acquisition unit (11I).

  • Publication number: 20240164692
    Abstract: An electrocardiogram analysis assistance device (10) including: a peak estimation model (13C) employing waveform data of partial segments of waveform data in an electrocardiogram as input information and employing peak information indicating whether or not a predetermined type of peak related to electrocardiogram analysis is present as output information; an analysis waveform acquisition unit (11C) that acquires waveform data in an electrocardiogram for analysis; an analysis waveform select and extract unit (11D) that selects and extracts waveform data of a predetermined first period from the waveform data acquired by the analysis waveform acquisition unit (11C) as analysis divided waveform data, while each time shifting a predetermined shift period that is a shorter period than the first period; and a derivation unit (11E) that derives the peak information by inputting the analysis divided waveform data selected and extracted by the analysis waveform select and extract unit (11D) into the peak estimation mod

  • Patent number: 5572678
    Abstract: Data communication method and system for transmitting a large amount of data via a network such as LAN to which a plurality of stations or terminals are connected, through a simplified processing procedure with high reliability and high efficiency while suppressing influence to other communications. The large amount of data is transmitted from a sender station to a plurality of receiver stations by utilizing a connectionless communication service, while inter-station reception acknowledging/retransmitting processings are performed by using a connection-oriented communication service. The large amount of data to be transmitted is divided into a plurality of blocks, and inter-block delay time is set on the basis of station status factors such as a permissible load increase rate of the CPU of the individual stations.
