Procena interakcije i vremena odziva biosignala pri različitim modalitetima fizioloških povratnih sprega / Assessment of interaction and response time of biosignals in different modalities of physiological feedback loops

<p>Teza istražuje mogućnost kori&scaron;ćenja kopule u finoj analizi međusobne zavisnosti kardiovaskularnih signala. U tu svrhu kori&scaron;ćene su različite GoF (Goodness of Fit) tehnike i matematički alati bazirani na kopuli. Predložena metoda određuje nivo zavisnosti kao funkciju vremenskog ka&scaron;njenja signala pulsnog intervala u odnosu na signal sistoličkog krvnog pritiska i omogućuje uvid u mehanizme otkucaj-po-otkucaj regulacije krvnog pritiska. Farmakolo&scaron;ka validacija je izvedena administracijom lekova koji inhibiraju autonomni nervni sistem, pri čemu su dobijeni rezultati imali jasan fiziolo&scaron;ki odziv.</p> / <p>The thesis investigates a possibility to apply a copula method for a more refined analysis of mutual dependency of cardiovascular signals. Different GoF (Goodness of Fit) techniques and mathematical tools based on copula are applied to prove this possibility. Proposed method determines the level of dependency of the pulse interval response in respect to the systolic blood pressure for different time lags and provides further insight into the beat-to-beat regulation of blood pressure. Pharmacological validation of the method was performed by administration of autonomic blockers drugs, as the obtained copula response was in accordance with the physiological interpretation.</p>
