| Heart rate variability (HRV) is the normal and healthy
variation in the rate at which the heart beats. It is
measured using an noninvasive electrocardiogram, (ECG/EKG)
or a finger sensor that measures the blood volume pulse
(BVP). |
| |
| HRV is an indicator of sympathetic and parasympathetic
nervous systems function and is the strongest single
predictor of death after accounting for medications,
demographics, and multiple clinical factors.[1] |
| |
| But it is also used by therapists to synchronize with
their patients physiology. Once breathing rates and
heart rhythms are coordinated, there is an emotional
rapport between people that breaks down barriers in
communication. |
| |
| Low heart rate variability (HRV) is an independent
risk factor for sudden cardiac death, all-causes death,
and cardiac event recurrence. [2, 3] HRV is defined
as the fluctuations in heart rate (HR) from beat-to-beat
as measured in milliseconds. |
| |
| Mounting evidence points to the efficacy of HRV biofeedback
for autonomically mediated disorders and for Stress,
Anxiety, Depression, Chronic pain, Fibromyalgia, IBS,
Anxiety Disorders, Hypertension, and other disorders |
| |
| HRV can be explained in terms of Stephen W. Porges
"Polyvagal Theory" (Porges, 1995) |
| |
"The evolution of the autonomic nervous system provides
an organizing principle to interpret the adaptive
significance of physiological responses in promoting
social behavior. According to the polyvagal theory,
the well-documented phylogenetic shift in neural regulation
of the autonomic nervous system passes through three
global stages, each with an associated behavioral
strategy.
The first stage is characterized by a primitive unmyelinated
visceral vagus that fosters digestion and responds
to threat by depressing metabolic activity. Behaviorally,
the first stage is associated with immobilization
behaviors. The second stage is characterized by the
sympathetic nervous system that is capable of increasing
metabolic output and inhibiting the visceral vagus
to foster mobilization behaviors necessary for 'fight
or flight'. The third stage, unique to mammals, is
characterized by a myelinated vagus that can rapidly
regulate cardiac output to foster engagement and disengagement
with the environment.
The mammalian vagus is neuroanatomically linked to
the cranial nerves that regulate social engagement
via facial expression and vocalization. As the autonomic
nervous system changed through the process of evolution,
so did the interplay between the autonomic nervous
system and the other physiological systems that respond
to stress, including the cortex, the hypothalamic_pituitary_adrenal
axis, the neuropeptides of oxytocin and vasopressin,
and the immune system. From this phylogenetic orientation,
the polyvagal theory proposes a biological basis for
social behavior and an intervention strategy to enhance
positive social behaviour". [4] |
