According to leading medical institutions such as Stanford, Harvard and the Mayo Clinic, stress is responsible for more than 90% all disease. Most people are stressed to some degree and many are not aware of it. This may be due to the fact that the brain is a giant filter and pattern matcher. When a condition becomes familiar the brain filters it out, even if it is not good for you.

HRV is the latest buzz word in the digital health revolution. It provides an objective measure of the stress or “fight or flight” response in your nervous system, and insight into situations, thoughts and behaviors that cause stress. In addition, it is a measure of systemic health and is an early indicator for heart disease and hypertension.

Legacy HRV measurement systems were expensive, bulky and did not provide meaningful feedback for the general population. Thanks to mobile platforms such as smart phones and tablets, HRV is available to the consumer, providing an accurate and easy way to measure and manage the weak link in the chain, also known as stress.

  5. 5. 5 What Does it all Mean?? Am I Healthy? SweetWater Health LLC Typical Dashboards
  6. 6. SweetWater Health LLC Confidential The Science of HRV  What is Heart Rate Variability (HRV)?  What does a healthy HRV look like?  HRV in the mainstream 6
  7. 7. HRV and Vagal Tone 7  The vagus nerve is the 10th of 12 paired cranial nerves and controls parasympathetic innervation of the heart and acts to lower the heart rate.  Vagal innervation is a mediator of HRV and therefore HRV is an indication of Vagal Tone  The higher the HRV, the stronger the Vagal Tone  In the past decade, college sports teams and world-class athletes have been increasingly using HRV to monitor fatigue and recovery from workouts.

  8. 8. 8 HRV and the Autonomic Nervous System SweetWater Health LLC Confidential The Autonomic Nervous System (ANS) has two branches: - Sympathetic - Parasympathetic Sympathetic “Fight or Flight” Branch speeds the heart up Parasympathetic “Rest and Digest” Branch slows the heart down
  9. 9. Fractal Patterns of HRV • Wavelet analysis is used to analyze heart rhythm • It turns out that the a healthy heart rhythm exhibits a fractal structure • Small changes in the “input” (the nervous system) results in larger changes in the fractal structure. – The Butterfly Effect • This fractal structure will reflect small changes in the nervous system – Enables early dis-ease detection SweetWater Health LLC Confidential (TOP) Color-coded wavelet analysis of a heart rate time series in health (Bottom) Color-coded wavelet analysis of a heart rate time series of patient with OSA Goldberger A L et al. PNAS 2002;99:2466-2472
  10. 10. So What Does This Mean to Me? 10  HRV is an indication of your resilience – the ability of the nervous system to respond and recover from physical or psychological stressors  Sympathetic “Fight or Flight” response, also known as Stress, can be measured with HRV  According to leading medical experts 90% of diseases and illnesses are due to stress  Stress becomes the norm and the brain filters the familiar so we don’t know we are stressed  Chronic low HRV is an indication of systemic health (psychological or physical) issues SweetWater Health LLC Confidential
  11. 11. Other Important Information on HRV • HRV value is dependent on length of measurement • HRV taken at same time each day • First thing in the morning while lying in bed is recommended • Try to keep a blank mind. Thoughts about a busy day can effect the reading – In same position • Lying down • Sitting • Standing – Measurement for same length of time each day (3 minutes typical)  HRV has a circadian rhythm  HRV is dependent on body position SweetWater Health LLC Confidential 6am 12pm 6pm 12am Circadian Rhythm HRV Time of Day

  17. 17. Closing Comments  Digital Health, particularly personal mobile health apps and devices, are changing the way we take care of ourselves – We are taking charge of our health and becoming our own and our family’s advocates  Personal health monitoring devices are give us data on our habits, including exercise and nutrition  “Quantified Self” and “Bio-Hacking” devices and programs provide a plethora of self-improvement venues  Because one size does not fit all, we need to monitor actual physiological health metrics such as weight, blood pressure and HRV  HRV has emerged as the latest “must know” physiological metric SweetWater Health LLC Confidential
