Classification of cardiac cycles
Lorenc, Patrik ; Škutková, Helena (referee) ; Vítek, Martin (advisor)
This work deals with the classification of cardiac cycles, which uses a method of dynamic time warping and cluster analysis. Method of dynamic time warping is among the elderly, but for its simplicity compared to others is still very much used, and also achieved good results in practice. Cluster analysis is used in many fields such as marketing or just for biological signals. The aim of this work is a general introduction to the ECG signal and the method and implementation of dynamic time warping algorithm. Subsequently, cluster analysis and finally the creation of the user interface for the algorithms.

ECG preamplifier with floating input and calibration
Florián, Antonín ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
This thesis deals with amplifiers that are usable for reading of EKG signals. The first part of the thesis deals with the history of EKG and with the features of the EKG signal. The second part of the thesis deals with general requirements and safety requirements that are imposed on EKG preamplifiers. A very important part of the thesis is the description of particular parts of EKG preamplifier and the ways how to acquire reduction of disturbance. The last part of this thesis is focused on design of ECG preamplifier with floating input and calibration. ECG preamlifier is designed for battery power.

Physical examinations for adults performed by nurse in practitioner´s ordination.
MANČUŠKOVÁ, Zdenka
This bachelor thesis deals with physical examination, the monitoring of physiological functions and the recording of cardiographs by nurses in private practice examination rooms. The thesis contains two parts. The first, and theoretical, part of the thesis is focused on the explanation of certain terms and a description of what it means to provide a physical examination, monitoring of physiological functions and recording cardiographs. The physical examination is focused around human senses. Sight (inspection), hearing (auscultation), touching (palpation), knocking (percussion), per rectum examination, and smelling are all considered methods of examination. Body temperature, breathing, pulse and blood pressure are considered physiological or vital functions. The electrocardiogram signifies cardiac activity in the form of a line, which is drawn by a gadget called an electrocardiogram (ECG). Activities executed by nurses in a private practice exam rooms can be divided into four groups: preventative, diagnostic, medical and administrative group. A nurse provides patients with medical educative materials, samples biological material, monitors clients physiological functions, gives injections, changes bandages, sends preventative examination invitations, orders medical material and equipment etc. The second part contains investigative research. The empirical investigation was performed using the qualitative method in a form of a semi structured interview and direct observation during the interview. In an interview with eight nurses, who all work in private practices, the nurses were asked 15 basic questions. The nurses were observed as they each examined a separate patient. The observation was done based on 32 observation criteria. The observation results were compared with the results of the interviews. Based on their close relation to physical examination, monitoring of physiological functions and cardiograph was added.
