In the recent years we have witnessed a rapid rise in technology that affects all areas of our lives, including the health care services. Here it is particularly difficult to follow the latest technological trends, as this often involves the use of data which is sensitive in its nature or complex and difficult to process, which makes it especially important to be careful when working with it. Nevertheless, trying new approaches to solve problems in the medical field using the latest technologies might bring positive results, which is the main reason for the topic of this thesis. Our goal was to design a database for storing digital ECG data, which would allow effective search. We aimed to achieve this using the ElasticSearch technology, being both a database management system and a search engine. In order for it to be usable by medical professionals, usually not skilled in database management, we also implemented a simple user interface. In last part of this thesis we also evaluate our solution based on a couple of user scenarios from the doctor's or researcher's point of view and present the advantages and disadvantages of this approach to solve the given problem.
