This Week In HRV Edition - Episode 16

This Week in Heart Rate Variability: Metabolic Syndrome, Nerve Blocks, EDS & Autonomic Health

In this episode of The Heart Rate Variability Podcast – This Week in HRV, we explore how the autonomic nervous system function connects metabolic disease, genetic disorders, targeted neural interventions, and the future of biofeedback science.

Episode Highlights

How Metabolic Syndrome drives chronic sympathetic overactivation and reduced HRV
Experimental evidence showing how the stellate ganglion block directly alters HRV and sympathetic tone
New data validating dysautonomia in Ehlers–Danlos Syndrome using HRV and autonomic testing
Why HRV is emerging as a critical clinical and research biomarker
A preview of the 2026 AAPB Annual Scientific Meeting and why it matters for clinicians and researchers

Key Takeaway

Heart rate variability is a universal marker of resilience, translating metabolic stress, genetic vulnerability, and neural interventions into measurable physiological signals. HRV is no longer just a wellness metric—it's a clinical and scientific lens into autonomic health.
