Didelė dalis širdies susirgimų diagnostinių kriterijų gaunama registruojant ir analizuojant kardiosignalus, kurie atspindi tiek elektrinės širdies veiklos sutrikimus (EKG), tiek ir hemodinaminės bei mechaninės veiklos pokyčius, t.y. impedanskardiograma (IKG) ir seismokardiograma (SKG). Dar daugiau, efektyvus širdies susirgimų diagnostikos problemų sprendimas yra naujų kardiosignalų analizės technologijų kūrimas. Jau kelis dešimtmečius Furjė transformacija taikoma EKG dažnumų analizei, tuo tarpu kai IKG ir SKG dažnio charakteristikų vertinimui šis metodas nebuvo naudojamas. Darbo tikslas buvo p

Abstract:

Plaučių arterijos trombinė embolija (PATE) – sunki ūminė ir neretai atkrintanti širdies ir kraujagyslių liga. Tik miokardo infarktas ir galvos smegenų insultas yra dažnesni negu ūminė PATE. Ūminės PATE diagnostika nėra lengva. Klinikiniai simptomai dažnai esti neraiškūs ar nespecifiniai. Šiuolaikinėje klinikinėje praktikoje pirmo pasirinkimo tyrimas įtariant ūminę PATE yra plaučių arterijos kompiuterinės tomografijos (KT) angiografija. Sergančiųjų, kuriems dėl plaučių embolijos dar nėra išsivysčiusi sisteminė arterinė hipotenzija, mirštamumo rizika priklauso nuo embolijos apimties ir dešiniojo
