How Does Heart-Focused Breathing Affect Your Heart Rhythm?
With slow, deep breathing….
Inspiration: heart beats faster
(sympathetic activation)
Expiration: heart beats slower
(parasympathetic activation)Slide25
Respiratory Sinus ArrhythmiaSlide26
Physiological Mechanisms of
of Respiratory Sinus ArrhythmiaSlide27
Mechanisms for Respiratory Sinus Arrhythmia
Inspiration reduces intrathoracic pressure leading to increased venous return.
Right atrium stretches.
Impulses from the right atrial receptors produce the “Bainbridge reflex”:
-
Increased right atrial pressure
stimulation of stretch receptors (=volume receptors) in the atrial wall
-Produces discharge of impulses along afferent vagal fibers to the medulla oblongata
- Leads to stimulation of the vasomotor centre
efferent impulses along the sympathetic nerves to the heart increase of heart rate.Slide28
Mechanisms for Respiratory Sinus Arrhythmia
On exhalation, extra blood from lungs enters left heart and is pumped into aorta so arterial pressure increases.
Impulses from the arterial baroreceptors of the aortic arch & carotid sinus respond to increased arterial pressure.
Parasympathetic (vagal) nerves are stimulated and
heart rate decreases
during expiration.
Also intrathoracic pressure increases leading to decreased venous return and no right atrial stretching.

Connection between Cardiac Intrinsic Nervous System and HRV
Hormonal, chemical and pressure information is translated into neurological impulses by the heart's intrinsic nervous system and is sent from the heart to the brain through several afferent pathways.
The resulting integrative signal that encompasses the continually changing chemical, hormonal and dynamic structural properties of the cardiac tissue is the
Heart Rate Variability.Slide35Slide36
Connection between Cardiac Intrinsic Nervous System and HRV
When the HRV signal reaches the limbic and cortical areas of the brain, it can be modified (with or without conscious intention).
The modified signal is sent back to the intrinsic nervous system of the heart and other organs via the ANS resulting in changes in physiological function. Slide37Slide38Slide39

SUMMARY
Display of Heart Rate Variability provides a window to your inner body to show you your stress level at that moment.
Use of slow, deep breathing and positive feeling while looking through the ‘window’ (biofeedback) can reduce your stress level and make you coherent.
When your heart produces a coherent HRV signal, all the cells in your body benefit as do all the people around you.Slide59
