Does coronary artery bypass grafting (CABG) alter heart rate variability in patients with severe coronary artery disease?
CABG alters cardiovascular autonomic function, characterized by an increase in high-frequency power and a decrease in low-frequency power of heart rate variability up to 30 days post-operation.
Hossen et al. (2017) studied this question.
