Abstract:Objectives
The purpose of this study is to explore the changes in HRV before and after cardiac surgery and the relationship between HRV and quality of life.
Methods
A total of 21 patients who received cardiac surgery were included in this study. All cases were conducted with a five-minute ECG uploaded by a Bluetooth signal three times. The ECGs were measured before the operation (1st), after the operation (2nd), and one month after the operation (3rd). The parameters of HRV included: standard deviation of no… Show more
