Borovičková, Michaela ; Tannenberg,, Milan (referee) ; Sekora, Jiří (advisor)
Proposal On Demand type pacemaker for educational purposes is designed and realized in the programming environment of LabVIEW. The thesis is a general description of pacemakers with the distribution according to various criteria including the type and duration of stimulation, scope, etc. Specifically, it dealt with a type of pacemaker On Demand system and made a proposal for implementation. To compare the effectiveness of the R wave detector includes a LabVIEW implementation of three selected methods for detection of R wave and by squaring the filtered signal, detecting the filtered envelope and wavelet transform. The outcome is a virtual pacemaker stimulation pulse with adjustable amplitude and pulse width.

Nursing care about a patient related to pacemaker implantation
Kazmířová, Jitka ; Zvoníčková, Marie (advisor) ; Osmančík, Pavel (referee)
Pacemaker implantation is a relatively common treatment of bradyarrhythmias today. This work deals with the nursing care about a patient who undergoes this surgery. The theoretical section summarizes the implantation issue, its indications, available devices and describes the typical course of the implantation. The practical part presents a case report. A fifty-six year old female patient undergoes a pacemaker implantation. She suffers from sick sinus syndrome manifested with bradycardia and palpitations, recently states of weakness and dizziness appeared, there were several collapses. The nursing process is handled according to the Model by M. Gordon. Particular attention is paid to mental state of the patient. Education of is also promoted. The patient must properly understand the reason for pacemaker implantation indication. She must also be advised of the necessary regimen after the surgery, which is an essential part of the treatment. Objectives that were set out in the plan of nursing care were achieved.

Social environment of transforming Karlín
Korytářová, Jana ; Ouředníček, Martin (advisor) ; Ptáček, Pavel (referee)
The main objektive of my thesis is a knowledge of social environment of prague district Karlín, one of the most dynamic part of inner Prague, which is undergoing a transformation of a physical, funcional and social structure. The concept of social environment is used in this work, whereby the social environment is consisted of a social structure and a social climate of a locality. By an analyse of the social, physical and funcional structure and a research of daily rhythms it tries to identify main pacemakers, to deeply learn about proceses and key moments during the day, which structurated the locality, and to capture social groups of users of the locality. The research is focused on three selected basic administrative units: 'Karlín - západ', 'Rohanský ostrov' and 'Za Invalidovnou'. Each of these localities has its own daily rhythm, which is structurated by the resident population and the temporarily present population,and different social environments, which influence each other, are dependent on each other and create the whole character of the prague district Karlín.The work tries to deepen and criticaly evaluate a current metodology. Keywords Karlín, Prague, social environment, social climate, social structure, daily rhythm, pacemaker, locality, mobility, time geography.

The influence of pacemaker implantation on the patient´s life
HOLUBOVÁ, Kateřina
Bachelor thesis concerns with the issue of perception and effect of the pacemaker on patient and his life. The theoretical part deals with particular illnesses as indications to a permanent cardiac stimulation. It also describes individual examinations that a cardiological patient can undergo. Major category comprises of regime measures and recommendations on how to perform with a pacemaker. This category is systematically divided into specific spheres, in which a problem or a potential risk for the pacemaker as well as for the patient can arise. The practical, research part is done with a help of a qualitative research survey with a half-structured interview as a tool of information obtaining. The questions were drawn in order to cover the life before pacemaker´s implantation, during the stay in hospital and to catch the following adaptation to the pacemaker and to this reality. The research group comprised of 10 patients implanted 4 - 8 months before the survey. The aim of this thesis was to find out what effect the pacemaker and his implantation have. The results show the effect of pacemaker mainly in connection with complications experienced. Our respondents admitted that adaptation to the pacemaker took them some time. The exception was the respondent who did not accept the pacemaker, especially in connection with the feeling of the mechanism in the body and the visibility of the devices under the skin. From the interviews with the respondents, we clearly show that their lack of a brochure, information material about the risks associated with this problems. The results obtained and information collected lead to our decision to issue an informative leaflet for patients, which also became an output of the bachelor thesis. This booklet contains the experiences of patients who have already had a pacemaker implantation.

Daily rhythm of university college
Kadleček, David ; Pospíšilová, Lucie (advisor) ; Fialová, Dana (referee)
Daily rhythm is a concept that has recently brought new insights into the description of how the city operates, the real number and movement of its inhabitants. It reveals facts that are not available in traditional statistical sources or are captured inaccurately or inadequately in detail. However, individual case studies are time-consuming and have not yet been implemented in a number of locations. The main aim of my work was to describe the daily and weekly rhythm of a chosen college dormitory and its most important pacemakers. The dormitory complex on the 17. listopadu street, which belongs to Charles University, fulfills a residential function and its rhythm thus corresponds to this model. Most people are present here in late night hours on weekdays. In the morning, there is a steep drop in the number of residents, with a maximum of departures between eight and nine o'clock, and a more gradual increase in the afternoon. On Saturdays, there are significantly fewer people in the area and the rhythm of arrivals and departures is much more balanced. The most important external pacemaker are university classes, the most important pacemaker inside the complex is the canteen, which causes a temporary increase in the number of people in the locality at noon. Keywords: daily rhythm, pacemaker,...

Nurses' knowledge of electrocardiography
Fialová, Iveta ; Křivková, Jana (advisor) ; Nikodemová, Hana (referee)
The bachelor thesis deals with the general knowledge of nurses in the area of electrocardiography, hence also its name Knowledge of nurses about electrocardiography. In the theoretical part, electrography, its history, recordings, pathological rhythms and nursing care associated with rhythm detection are described. In the empirical part, the results of quantitative research carried out by the questionnaire are interpreted over the methodology. At the end of the thesis are summarized the results of the questionnaire survey, which shows shortcomings in education during preparation for the general nurse's profession. These deficiencies are then manifested by insufficient knowledge of the recognition of basic pathological ECG rhythms, eventual defibrillation of some pathological rhythms. The lowest knowledge in this area has nurses with secondary education only. From the questionnaire survey, it is clear that nurses would appreciate not only more tuition during their general nurse training, but would also take part in electrocardiography workshops.
