Implication

Validated BRS methods yield consistent estimates; leaves open standardization for clinical adoption.

Key Points

This review aims to compare modern techniques for evaluating spontaneous baroreflex sensitivity based on blood pressure and heart rate data.
Evaluated various signal processing techniques for baroreflex sensitivity assessment
Discussed the influence of respiratory and other factors on BRS estimates
Compared data from multiple studies to identify consensus on BRS patterns
Modern techniques generally provide comparable information on baroreflex sensitivity changes over time
Estimates remain consistent across a variety of physiological and pathophysiological states
Averaging over a few minutes improves the reliability of BRS assessments
