Heart rate variability¶

Type: Entity
Confidence: ★★★☆☆ Promising

Evidence Graph¶

Summary¶

Heart rate variability synchronizes with brain waves through vagal mechanisms. High-frequency HRV shows stronger coupling with brain oscillations across delta, theta, alpha, beta, and gamma bands. Respiratory sinus arrhythmia (RSA) quantifies myelinated vagal activity - higher RSA improves emotion regulation.
