Heart Rate Variability (HRV)

Electrocardiograph

heart rate variability hrv why is it important
Heart Rate Variability (HRV)Why is it important?
  • Higher levels of resting HRV have been associated with:
    • Well balanced ANS
    • Greater overall health
    • Greater emotion regulation
    • Effective stress coping strategies
    • Increased resilience under stress
    • Increased attention control
heart rate variability hrv why is it important1
Heart Rate Variability (HRV)Why is it important?
  • Low HRV predicts worsening:
    • Coronary heart disease
    • Atherosclerosis (Wennerblom, et al 2000)
    • Elevated triglycerides (Jensen-Urstad M, et al 1998)
  • Low HRV Correlates with:
    • Diabetes (Laitinen T, et al 1999)
    • Obesity (Karason K, et al 1999)
    • Multiple metabolic syndrome (Liao D, et al: 1998)
    • Hypertension (Schroeder EB, et al 2003)
heart rate variability hrv why is it important2
Heart Rate Variability (HRV)Why is it important?
  • Low HRV linked with:
    • Depression (Carney RM et al. 2001)
    • Social isolation (Hughes JW et al. 2000)
    • Suppressed anger (Inmaculada L et al. 2009)
  • Increased risk of mortality (Framington Heart Study: Singh et al., 1998).
heart rate variability hrv intervention results
Heart Rate Variability (HRV)Intervention Results
  • Reduced blood pressure in hypertension (McConville, 2012)
  • Improved asthma (Lehrer, 2000)
  • Reduced symptoms of stress (Nolan RP, 2005)
  • Increased calmness and well-being (Friedman, 2000)
  • Increased emotional stability (McCraty, 2001)
  • Improved cognitive performance (McCraty, 2001)
  • Improves hormonal balance (McCraty, 1998)
  • PTSD symptom reduction (Zucker et al. 2009)

vagal tone definition
Vagal ToneDefinition
  • Vagal
    • Referring to the action of the vagus nerve; the 10th cranial nerve, which relays information between the brainstem and most of the internal organs
  • Tone
    • Tone is a term commonly used to refer to systems in continuous and partial states activity, such as “muscle tone”
    • In this context it means something similar to “tension” or “strength”
low vagal tone
Low Vagal Tone
  • Linked to high inflammation (Thayer & Sternberg, 2006) and;
  • Forecasts higher risk for myocardial infarction and decreased odds of survival after heart failure (Bibevski & Dunlap, 2011).
high vagal tone
High Vagal Tone
  • Is associated with superior abilities to regulate emotions (Thayer, Hansen, Saus-Rose, & Johnson, 2009)
  • Show greater positive emotionality (Oveis, Cohen, Gruber, Shiota, Haidt, & Kelther, 2009) and;
  • Show greater gains over time in their positive emotions (Kok & Fredrickson, 2010).

improving hrv
Improving HRV
  • Lifestyle adjustments:
    • Exercise
    • Omega-3 intake
    • Yoga/qigong
    • Acupuncture
    • Emotional self- management (positive emotions)
    • Breathing practices (resonant frequency breathing)
    • HRV Biofeedback
    • Wine

Heart Rate Variability
  • HRV 3 domains
    • Sympathetic component;
    • Parasympathetic component coupled with respiration (RSA) … bottom-up;
    • Parasympathetic component independent from respiration… top-down cortex influence

what is resonant frequency
What is Resonant Frequency?
  • Current research suggests that every individual has a “resonant frequency” at which heart rate variability is the greatest.
