ECG Data From Cyclists Recorded With Polar H10

This is a set of ECG data of cyclists recorded with a Polar H10 chest belt. The data was collected between May 2025 and July 2025 as part of the MSc Thesis of Victor Gutgesell. The dataset features twenty (20) different recordings totaling a little more than 48 hours of ECG data. All datasets are annotated according to ANSI EC57 standarts with the labels: N for normal beats, S for supraventricular ectopic beats, V for ventricular ectopic beats, F for fusion beats, Q for unclassifiable beats, and ~ to denote the beginning of a noisy segment within the recording. The data was annotated in a custom Python application. You can find the GitHub link below. This table shows the prevalence of each label present in the recordings. # N S V F Q Total ~ 1 18430 38 8 0 1 18477 0 2 12894 6 5 0 2 12907 0 3 22096 3 1 0 1 22101 0 4 17644 24 0 0 7 17675 4 5 16940 1 0 0 1 16942 1 6 18567 2 457 0 1 19027 0 7 20390 2 0 1 11 20404 3 8 20263 0 0 1 10 20274 4 9 14081 0 0 0 0 14081 0 10 19528 2 0 0 0 19530 0 11 18789 0 0 0 8 18797 3 12 17707 3 0 0 11 17721 1 13 18799 10 0 0 5 18814 2 14 17971 4 34 0 35 18044 17 15 18870 1 0 0 4 18875 3 16 23457 0 0 0 2 23459 1 17 17873 0 0 0 8 17881 4 18 20486 21 0 0 42 20549 15 19 25558 3 1 0 5 25567 0 20 16746 2 3 0 11 16762 15
