Mar 20, 2026
Dr Deborah Rozman, behavioural psychologist and CEO of HeartMath Institute, explores heart–brain science and HRV research. She discusses heart coherence, how breath plus positive feeling can shift physiology, practical biofeedback demos and device-free techniques. Conversation covers resilience, wearables and why heart rhythms matter for clarity, stress and performance.

INSIGHT

HRV Is Beat-To-Beat Flexibility Not Average Heart Rate

  • Heart rate variability (HRV) is the beat-to-beat timing variability and not the average heart rate, and it reflects autonomic flexibility tied to health outcomes.
  • Deborah Rozman explains HRV shows rapid sympathetic/parasympathetic shifts, greater in infants and predictive of all-cause mortality when low.
INSIGHT

Emotional States Show Up As HRV Waveforms

  • HRV waveform patterns reveal emotional state: stressed emotions create jagged, irregular patterns while positive states create smooth sine-wave patterns.
  • Rozman cites a 1995 American Journal of Cardiology study linking jagged HRV patterns to anger, anxiety and stress.
ANECDOTE

Workshop Demo Shows Stress Then Coherence On HRV Sensor

  • Dr Paul Taylor describes using the Inner Balance sensor in workshops to stress participants then smooth HRV with slow controlled breathing.
  • He recounts counting backwards by sevens and hassling participants to produce jagged HRV that then smooths with breathing.
