Rekonstruktsiya tokovykh istochnikov serdtsa v obratnoy zadache EKG: Algoritmy i ikh analiz (Russian Edition),Used
Delivery time: 8-12 business days (International)
Reshaetsya obratnaya zadacha elektrokardiografii zadacha opredeleniya kharakteristik tokovykh istochnikov serdtsa po izmerennym elektricheskim potentsialam na poverkhnosti grudnoy kletki. Rassmatrivayutsya algoritmy rekonstruktsii ekvivalentnykh tokovykh istochnikov po izmerennym potentsialam, pozvolyayushchie opredelit' geometricheskie parametry kvaziepikarda i raspredelenie tokovykh istochnikov na kvaziepikarde. Predlozheny spektral'nyy i algebraicheskiy algoritmy rekonstruktsii. Razrabotana ob"emnaya dinamicheskaya model' bioelektricheskoy aktivnosti serdtsa, otrazhayushchaya ego geometriyu i osnovnye elektrofiziologicheskie protsessy, protekayushchie v miokarde v khode protsessa vozbuzhdeniya. Dannaya model' pozvolyaet vosproizvesti elektricheskie potentsialy, priblizhennye po amplitudnym i vremennym kharakteristikam k real'nym potentsialam serdtsa. Polozhitel'nye rezul'taty aprobatsii predlozhennykh algoritmov s pomoshch'yu ob"emnoy dinamicheskoy modeli serdtsa pozvolili sdelat' vyvod o vozmozhnosti ikh primeneniya v elektrokardiografii dlya polucheniya i otobrazheniya informatsii o prostranstvennovremennoy strukture tokovykh istochnikov serdtsa.
