The database of indices computed from RR-intervals of length 512 of 41 patients at rest hospitalized due to the episode of acute ischemic stroke

This dataset contains the data that was a basis for the results discussed in the paper “Persistent homology as a new method of the assessment of heart rate variability” by Grzegorz Graff, Beata Graff, Paweł Pilarczyk, Grzegorz Jabłoński, Dariusz Gąsecki, Krzysztof Narkiewicz,  Plos One (2021), DOI: 10.1371/journal.pone.0253851.
The file is in the csv (comma-separated values) format that is easy to import by most types of spreadsheet software. All the patients are identified by the string “STR” (for stroke) followed by a 3-digit identifier; note the non-contiguous numbering.
The file indices_STR.csv contains all the indices that were calculated for  the  purpose  of  their  potential  use  in  the  paper;  in  particular,  all  the standard hrv (heart rate variability) indices and all the topological indices introduced in the paper are contained in this dataset. These indices are listed and described in the file indices_STR.pdf.
