Evaluation of heart arrhythmias
Šromová, Michaela ; Kozumplík, Jiří (referee) ; Provazník, Ivo (advisor)
The thesis is a brief description of the anatomy and electrophysiology of the heart. The thesis also describes the different types of electrocardiogram and cardiac arrhythmias with a description of their treatment. The next section provides design of a programme for the classification of selected types of arrhythmias, and three options for rhythm detection, using the length of RR intervals, finding extremes of P and R waves, measuring the length of intervals and heights of amplitudes. The practical part of this work was to create a rhythm classifier assigning appropriate treatment of arrhythmias, verification of its functions on the signals available from the library of arrhythmias and its evaluation.

Evaluation of ECG in prehospital care
GROSSMANN, Matyáš
This bachelor thesis deals with the issue of ECG evaluations in pre-hospital emergency care by a paramedic. The thesis is divided into two parts, theoretical and practical. The theoretical part focuses on the definition of a paramedic and his/her competencies, instrumentation, and anatomy of the cardiac conduction system. Furthermore, it describes the methods of ECG evaluations, types of arrhythmias and their treatment in pre-hospital emergency care. The major objective of the thesis was to map the ability of paramedics to interpret the waveforms of ECG recordings. The practical part of the bachelor thesis was based on a quantitative research investigation carried out in the form of non-standardized questionnaires. The research sample consisted of 51 paramedics from the Region of South Bohemia. The research took place from March to April 2023, with the participation in it being entirely voluntary. The collected data were subsequently analysed and compiled into graphs, which were completed with a commentary. The knowledge in interpretation of ECG waveforms was mapped by a series of 24 questions in which the respondents could obtain a total of 35 points. The high knowledge of the respondents is demonstrated by the fact that three quarters of the respondents achieved 80 percent or more correct answers. Two hypotheses were determined in the research part. The first hypothesis suggested that the knowledge in interpreting ECG waveforms is affected by the length of experience. The respondents working in emergency medical services for 0-3 years had the highest score (median 93%). However, the result of the Kruskal-Waliss test revealed no statistically significant difference between the four groups compared (p = 0.51). The second hypothesis assumed that the knowledge in interpreting ECG waveforms is influenced by the type of previous workplace. The respondents who had worked in the accident and emergency department before joining the emergency medical service were the most proficient in ECG assessment and interpretation (median 96%). Here again, the Kruskal-Wallis test revealed no statistically significant difference between the four groups compared (p = 0.31). The obtained results can provide useful information for the possible implementation of an educational seminar for paramedics.

Treatment of cardiac arrhythmias related to nursing care
NOVÁKOVÁ, Jaroslava
Nursing care continuing the treatment of cardiac arrhythmias is an inseparable part of the patient?s care. As there are various types of arrhythmias and different types of treatment, similarly, the subsequent nursing care has its specifics as well. It relates not only to the post-treatment care but also to pre-surgery preparation and subsequent education. The theoretical part of the thesis contains the information on arrhythmias, their development and treatment. Organizations associating nurses working in arrhythmologic centres are mentioned as well. The practical part consists of the survey research. The quantitative enquiry is conducted in arrhythmologic centres by means of questionnaires addressing the nurses. The qualitative part contains interviews with patients who underwent some of the types of cardiac arrhythmia treatment. The objective of the thesis was to find out whether the nurses are aware of the specifics of the nursing care that follows the treatment of cardiac arrhythmia, in which stage the treatment is the most demanding for nurses and whether they can apply standardized nursing procedures in their work. Another objective is focused on mapping of the educative activity within the nursing care. Interviews with the patients are aimed at the areas of admission, prior to surgery, after surgery and during education. They should outline the view from ?the other side?. All the defined hypotheses were confirmed. The cardinal hypothesis of the thesis was the assumption that nurses, when providing nursing care to patients undergoing treatment of cardiac arrhythmias, do not work according to standardized nursing procedures. Subsequently, a draft of standardized nursing procedure focused on nursing care of patients undergoing implantation of a permanent cardiostimulator was prepared ? it could be applied in the University Hospital in Plzeň where most of the enquiry was conducted.
