BigIdeasLabSTEP: smartwatch HR vs ECG across Fitzpatrick I–VI (53 adults, 6 wearables, Duke 2019). Recorded signals include hr, ecg-derived-hr. Licence: PhysioNet Restricted Health Data License 1.5.0.
This dataset was collected as part of a study on investigating the sources of inaccuracy in wearable optical heart rate sensors across a variety of activities (sitting, deep breathing, walking, and typing). The original study examined covariates including skin tone, signal lag, and device type. The dataset includes the heart rate given by the ECG and corresponding heart rate given by each smartwatch used in the study. Activity, skin tone, and subject ID are also included. This dataset was recorded in July-August 2019 and includes 53 participants. The data is completely de-identified and observations are time-synced.
