Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Based on the monitoring data of wearable devices, with cardiac output (CO) as the gold standard, this study intends to develop a non-invasive evaluation model of CO based on wearable data, and optimize the parameters to realize the cardiac capacity detection function in resting and exercise states on the wearable device.
