Wearable-based signals during physical exercises from patients with frailty after open-heart surgery

This data collection contains a single-lead electrocardiogram and triaxial
acceleration signals of 80 elderly frailty patients, who entered a cardiac
rehabilitation program after open-heart surgery. The signals were collected
using a chest-based heart rate monitor worn by the patients performing a
series of exercise tests for health status assessment. The tests include
veloergometry, 6-minute walk test, stair climbing test, timed up and go test,
and gait analysis on a treadmill. The signals are supplemented with the
demographic and clinical characteristics of the patients including the
Edmonton frail scale score and quantitative results of the exercise tests.
This data collection could be particularly useful in developing wearable
technology-based methods for (1) assessment of gait and balance in frailty
patients and (2) monitoring of heart response to daily physical stressors.
