Description	The proposed project is focused on study of relationship between electrical properties and blood flow in the heart ventricles. The main aim of the project is to reveal and confirm physiological origin of immediate change of QT intervals as a reaction on sudden change of heart rate and the following slow adaptation of QT interval. Animal experimental protocols for measurement on isolated hearts will be designed to build environment for setting various conditions of the heart. Animal experiments will be performed to record electrocardiographic signals from the hearts. The biosignals will be preprocessed by designed methods for effective noise reduction, ECG wave detection, and ECG cycle delineation. Further, methods for analysis of preprocessed biosignals to study QT interval behavior will be designed. The project will allow to confirm that immediate change of heart rate and corresponding change of blood flow cause immediate change and the following slow adaptation of QT intervals. Physiological origin of these fast and slow depolarization and repolarization periods will be described. (en) Navrhovaný projekt je zaměřen na studie vztahů mezi elektrickými vlastnostmi a průtokem krve srdečními komorami. Hlavním cílem projektu je popsat a verifikovat fyziologickou příčinu náhlé změny QT intervalu jako reakce na náhlou změnu srdeční frekvence a následnou pomalou adaptaci QT intervalu. Budou navrženy protokoly zvířecích experimentů pro studie na izolovaných srdcích tak, aby bylo možné nastavit různé fyziologické a patofyziologické podmínky. Bude provedeno měření na zvířecích modelech a zaznamenány elektrokardiografické signály. Zaznamenané biosignály budou předzpracovány navrženými metodami pro potlačení rušení, detekce vln a rozměření. Dále budou navrženy metody pro analýzu předzpracovaných signálů pro studie chování QT intervalů. Projekt umožní potvrdit, že náhlá změna srdeční frekvence a související změna průtoku krve srdečními komorami způsobuje náhlou změnu a následnou pozvolnou adaptaci QT intervalů. Bude popsána fyziologická podstata těchto rychlých a pomalých depolarizačních a repolarizačních dějů.
