Analysis of T wave alternations in programming language C - Radek Poul
Poul, Radek ; Vítek, Martin (referee) ; Rychtárik, Milan (advisor)
The thesis deals with detection of T-wave alternans. The presence of T-wave in surface ECG is recognized as a marker of electrical instability of heart in stage his repolarization, arise increased risk of emergence ventricular fibrillation and sudden cardiac death. The goal of our project is familiarize with methods of detection T-wave alternans. In particular spectral method and spectral method which was realized in variant for running reading values in time (“sliding window”). To suggest a QRS complex detector, localize the T-wave and to make TWA detection using spectral method and modified spectral method. This project is to be made in C language in appropriate user interface.

Patients with implanted cardioverter defibrillators
HEŘMANSKÁ, Marie
This Bachelor Thesis deals with the issue of implantable cardioverter defibrillator usage, namely with the impact of implantable cardioverter defibrillator on patient life and the details of nursing care in scope of implantation of these devices. The implantable cardioverter defibrillator (hereinafter referred as to "ICD") enables to prevent or avert heart failure which affects approximately 2 % of population. Nearly 3/4 of cases of sudden death take place at home and 2/3 of these cases are witnessed by other person. Indications for the ICD implantation are severe malignant ventricular tachycardia (ventricular tachycardia, fibrillation and chamber flutter) which rapidly lead to the circulation failure, unconsciousness and, finally, death. The rapid termination of such arrhythmias by ICD saves the life of its holder. The diagnostics shall commence by the standard electrocardiogram (ECG). The field study of the Bachelor Thesis includes results of the qualitative research based on the semi structured interview. The research group contained thirteen patients with implantable cardioverter defibrillator, residing in Středočeský kraj (Central Bohemia Region) and Jihočeský kraj (South Bohemia Region), who have had their ICD at least for a year. All respondents were asked ten basic questions as a part of the interview. The interviews were recorded over voice recorder and subsequently were directly transcribed to text. The interviews were processed while using the open coding, paper and pencil method. The data analysis produced five categories: Difficulties before the implementation of ICD, Changes in lifestyle after the implementation of ICD (with subcategories of Life certainties, Common activities, Employment, Driving and State of mind), Defibrillator shock, Nursing care and Importance of ICD for patients. The research shows that patients are predominantly satisfied with the nursing care. Nearly all respondents do not feel the need for increased nursing care while being in hospital. Patients greatly appreciated the wound care all respondents were satisfied with this precise type of care as no complications did occur while healing and the wounds healed per primam. I see imperfections in the patient education although ten patients state that they were duly informed, they were informed only by their doctor. Only one patient states that he was given "certain" information from the nurse. However, these results may be misrepresented by patients due to the time lapse (from the hospitalization). Furthermore, the research shows that ICD device does not influence common activities of majority of respondents. Nearly all respondents experience mental relief and the improvement of life quality. The respondents do not consider the restriction connected to the ICD usage to be negative. The majority of them try to observe given advices (in scope of driving, travelling, magnetic security systems, etc.) which do not restrict them in their common life significantly. Even though their disease is severe and endangers their life, the patients with these devices may travel abroad, do sports, work and live their normal life with less risk of sudden heart failure. Twelve respondents out of thirteen consider the ICD to be of great significance to their life. The outcome of this Bachelor Thesis is the Guide for ICD Patients.

Sudden Cardiac Death - Social Impact on Family
JIROUŠKOVÁ, Alžběta
Abstract The Bachelor´s thesis "A Sudden cardiac death - and its social impact on the family" deals with a sudden cardiac death and its influence on functionality of a basic element of the state ? the family. The main task of this thesis is to determine a total psychosocial impact of a sudden cardiac death on the relationships in the family and verify which psychosocial rehabilitation options are offered to the bereaved persons. The expected application of this thesis in practice should improve living conditions for the bereaved persons and to provide them with more information about this diagnosis. In the theoretical part the diagnosis of a sudden cardiac death was described in detail. The death that occurs within one hour after the first signs is a frequently discussed topic in professional medical circles. The heart disease is considered as the main risk factor. Therefore, doctors primarily concentrate on this area in the treatment and prevention. Nevertheless 25 percent of patients who died of sudden cardiac disease had no signs of heart disease. So it´s important to think about familial syndrome. The major role in therapeutic activities is played by antiarhytmic therapy, kardiovertru-defibrillator implantation or catheter ablation. The main objective of the research was to determine how the current society is informed about the risk of NSS, its causes and possible prevention. The possibilities of psychosocial rehabilitation for families with psychosocial impact from diagnosed sudden cardiac death of a family member were analyzed here as well. The first set of questions was focused on lifestyle diseases that are closely connected with NSS and significantly increase the risk. The answers revealed the current society is quite well informed about lifestyle diseases, mainly cardiovascular diseases. Despite this knowledge the Czech population health situation has not changed significantly and civilization diseases are growing instantly. Another set of questions focused on the NSS and its causes. A lot of survey respondents put emphasis on SAC prevention in contradistinction to experts who already work with endangered patients and focus on managing and control of life threatening arrhythmias. Approximately half of the respondents identified themselves as endangered because of their health problems (cardiovascular disease, obesity, diabetes, etc.) More than 95 percent of the respondents expected impacts on the family and its relationships caused by the sudden cardiac death of a family member. Only 8 percent of the respondents put emphasis on potential social-economic changes. The research dealt with a problem whether the public is well-informed about possibilities of psychosocial rehabilitation. And the findings indicate it is not. More than 58 percent of the respondents try to solve problems themselves or with help of their family or friends. The responses to the survey confirmed the assumption that majority of the respondents (80 percent) know only about financial support from the state to the bereaved persons. And they would use only this state support if their family member died. Common people consider the using of psychosocial rehabilitation unavailable or they believe it is intended for the target group of psychologically ill people, mentally handicapped, alcoholics and drug addicts. A most of them don´t know that it could be used by the bereaved persons (91.16 percent). Due to the activity developed by the MMR as counseling for bereaved persons, it seems that it could get better in the near future. The offered service called ?consultancy for the bereaved persons? could get widely into the public knowledge.
