HRV Interpretation
 HRV can vary greatly from person to person depending on health and fitness
 HRV can vary greatly for an individual from day to day and even hour to hour
 While there are “average HRV values” determined through clinical research, HRV
is dynamic and individuals will tend to have their own range
– Scroll down to see charts of “average HRV values” from some research papers
 Some athletes have HRV values that are magnitudes higher than average persons
 SweetBeat is about understanding and managing the nervous system and
not intended to diagnose anything. If you feel your HRV is “low” see your
doctor
 Athletes use HRV to guide training
– As seen on the next 2 charts, HRV power levels vary quite a bit
– The elite athlete has LF and HF power that are orders of magnitude higher than
average
– Don’t be alarmed if your HRV values are closer to average

Coherence
 Many SweetBeat customers use HeartMath coherence
training techniques – excellent!
 Coherence is associated with a “spike” at 0.1hz frequency
 There are industry standards for LF and HF frequency ranges
– LF = 0.04hz - 0.15Hz
– HF = 0.15hz – 0.4hz
 Stress is associated with a high LF with respect to HF (high
LF/HF ratio). Because coherence is associated with a high
power spike at 0.1hz, which falls into the HRV definition of LF,
coherence shows as high stress in SweetBeat.
SweetWater Health LLC Confidential
Coherence Visualized

 Coherence spike at 0.1hz
 Note very high power in the
LF range (0.04hz – 0.15hz)
and little to no power in the
HF range (0.15hz – 0.4hz)

SweetWater Health Tidbits
 SWH was founded in Feb. 2011 by Ronda Collier and Jo Beth Dow
 Idea came from the realization that in order to improve the world, individuals must
improve themselves
 Much of what needs improvement is subconscious thoughts and behaviors
 SWH created an app to alert an individual in real time when their nervous system
enters fight or flight, bringing subconscious reactions to the conscious mind
 An unexpected realization about how to identify good stress from bad stress
– Power levels of nervous system are high during good stress even if sympathetic
dominates – HRV increases when one is “in the zone” and highly creative
– Fight or flight response accompanied by low HRV and low power levels
 SweetBeat is about understanding and managing the nervous system
– Nervous system activity is the result of the coupling of biological oscillators
– This coupling (when healthy) results in a signal that is complex
(fractals, chaos, self-organizing)
 Athletes use HRV to guide training
– HRV is the reflection of vagal tone which is affected by overtraining
The Science of HRV
• What is Heart Rate Variability
(HRV)?
• HRV is a result of this tightly
coupled system trying to
keep your body system in
equilibrium
• HRV in the mainstream

HRV and Vagal Tone
12
 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 the mediator of
HRV and therefore HRV is an
indication of Vagal Tone
 The higher the HRV, the stronger the
Vagal Tone
 Higher HRV is an indication of an
individuals ability to “put the brakes
on stress” by mediating the
sympathetic control over the nervous
system and heart rate.

HRV and Vagal Tone
 HRV is an indication of your resilience – the ability of the nervous system to
respond and recover from physical or psychological stressors
 HRV has a circadian rhythm
 IMPORTANT: HRV measured values depend on length of measurement
 3-5 minutes
 24 hour
 IMPORTANT: HRV is age and gender dependent
 HRV may change day to day with your biorhythm or due to emotional or physical
stress
 HRV associated with willpower in several studies
 Chronic low HRV is an indication of systemic health (psychological or physical)
issues
 There are over 5,000 papers on HRV in the NIH database alone
 There are CPT reimbursement codes for HRV measurements
SweetWater Health LLC Confidential

HRV Parameters
 Heart Rate Variability is measured by several parameters:
 Time domain – These are standard statistical analysis of the heart beat time series
 Standard Deviation (SDNN)
 Root Mean Square of Successive Differences, (rMSSD)
 Heart Rate (HR)
 pNN50, TINN, Triangular index
 Frequency Domain:
 Very Low Frequency (VLF)
 Low Frequency (LF, associated with sympathetic activation)
 High Frequency (HF, associated with parasympathetic activation)
 Non-Linear:
 SD1/SD2, ApEn, SampEN
 SweetBeat calculates rMSSD, LF and HF
 The SweetBeat HRV value is a value from 0 – 100 and based on rMSSD
SweetWater Health LLC Confidential
16
rMSSD,LF, HF
 rMSSD is a reflection of Vagal Tone
 rMSSD is non-stationary and varies +/- 10 ms at rest
 Average rMSSD ranges from ~20ms to ~80ms depending on age and state of health
 Generally calculated on 3-5 minute window
 LF is associated with sympathetic nervous system
 Some contribution from parasympathetic
 HF is associated with parasympathetic nervous system
 LF/HF is ratio of sympathetic and parasympathetic
 So a high HRV means
 High rMSSD which means strong Vagal Tone or total variability
 LF, HF total power in optimal range for age and gender
 LF/HF < 2 is indication healthy stress levels

Editor's Notes

  1. Heart Rate, Blood Pressure, Respiration, Autonomic Nervous System (ANS) is a tightly coupled systemThis system is affected by our physical actions (exercise, standing up) and our thoughts and environmentAll aspect work in concert to keep us balanced and operating “within spec”It turns out that our heart beat or rather the pattern of the heart beat is a window into this tightly coupled system.This rhythm or pattern of the heart beat is called Heart Rate Variability (HRV)HRV is: The variation between each heart beatA reflection of resilience and elasticityA true cornerstone for multilevel health monitoring An energy biomarker in an interconnected biological systemTwenty years of research validates HRV as a significant metric for measuring healthHRV is a mainstream topic of researchSome HRV metricsSDNN – Standard Deviation of RR intervalspNN50 – Percentage of RR intervals/hour in which change in normal intervals exceeds 50msecrMSSD – Root Mean Square of Successive Differences of RR intervalsSDNN, pNN50, rMSSD all have published cutoff points for risk of sudden death from MIHRV provides insight into the nature of heart-related diseasesWhile there is still a gap in awareness of HRV between researchers and doctors in the medical community, HRV is an emerging biometricInsurance reimbursement codes accept HRV as a metric for measuring ANSMonitoring HRV allows individual to modify behavior, leading to positive change throughout the body’s tightly coupled systemHRV measurements.CPT Coding 95921 and 95922Two reimbursable CPT codes allow physicians to be paid for autonomic nervous system monitoring. These two reimbursable CPT codes for autonomic nervous system monitoring (95921 and 95922) were established in 1999. These CPT codes enable health care providers to be reimbursed for monitoring the autonomic nervous systems of patients where such monitoring is indicated. The reason for two CPT codes is simple. In order for physicians to get a complete look at autonomic nervous system functioning they must read both of its branches (Sympathetic and Parasympathetic) independently. CPT code 95921 is coded for parasympathetic nervous system monitoring and 95922 is coded for sympathetic nervous system monitoring. HRV measurements.
