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.

本数据集收录了80名心脏直视手术后参与心脏康复项目的老年衰弱患者的单导联心电图（single-lead electrocardiogram）与三轴加速度信号。该类信号采集自患者佩戴的胸部式心率监测仪，采集场景为患者完成一系列用于健康状态评估的运动测试过程中。本次运动测试包括踏车功量试验、6分钟步行试验（6-minute walk test）、爬楼梯测试、计时起立行走测试（timed up and go test）以及跑步机步态分析。本数据集同时补充收录了患者的人口统计学与临床特征数据，具体包括埃德蒙顿衰弱量表（Edmonton frail scale）评分以及各项运动测试的量化结果。本数据集可用于开发基于可穿戴技术的研究方法，具体应用场景包括：（1）评估衰弱患者的步态与平衡能力；（2）监测心脏对日常体力应激的反应。
