Does heart rate variability analysis predict imminent brain death in brain-injured patients?
Heart rate variability analysis demonstrates a progressive loss of autonomic nervous system activity prior to clinical brain death, highlighting its potential as an early, sensitive predictor.
Rapenne et al. (2000) studied this question.
