Key result
A new index of sympathovagal balance from independent component analysis had higher discrimination power in distinguishing the autonomic status of carotid stenting patients than the standard index.
Why the study?
Does a new index of sympathovagal balance from independent component analysis perform better than the traditional low-to-high frequency ratio in assessing autonomic status?

Does a new index of sympathovagal balance from independent component analysis perform better than the traditional low-to-high frequency ratio in assessing autonomic status?
A novel index of sympathovagal balance using independent component analysis provides better discrimination of autonomic status than traditional heart rate variability metrics.
Huang et al. (2011) conducted an observational in Carotid artery stenting. Independent component analysis index of sympathovagal balance vs. Ratio of low-to-high frequency spectra power of heart rate variability was evaluated on Discrimination power in distinguishing autonomic status. A new index of sympathovagal balance from independent component analysis had higher discrimination power in distinguishing the autonomic status of carotid stenting patients than the standard index.
