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.
