Searching for a similar time series fragment when solving a recognition problem via the example of an electrocardiogram

The article is devoted to searching for a time series fragment of an electrocardiogram. The purpose of this study is to identify defects in the work of the human heart. First of all, the desired pattern is selected. Next, a sampling window is arbitrarily selected in the electrocardiogram from the entire time series. The ST-index is used to find the fragment that looks like the given pattern. As a result of this study, a technique for finding the fragment was developed. At the end of the presented work, the task is formulated to conduct further research optimizing the developed methodology.
