Golden symmetry - an indicator of the norm and pathology of the human heart

The concept of «norm» is the key to biology and medicine. Recently, the norm has been associated with harmony. That which leads «opposites» to unity is harmony. It is closely related to the proportion of the golden ratio. The golden ratio is the basis of human health. Deviations from it can be used in medicine to diagnose pathological conditions. This fully applies to the work of the heart. The mathematical expression of harmony, symmetry is a method of assessing the norm of the heart. The golden proportion is manifested in the relationship of the temporal parameters of the cardiocycle, volumes of the left ventricle, types of blood pressure: pulse, diastolic, systolic. It was found that the golden proportions of systole, diastole and cardiocycle close to 0,382,0,618 are observed in men with a heart rate of 65 beats/min, in women - 55 beats/min. This mode of work of the heart corresponds to the rest of the body and is the norm. During physical activity, changes in the parameters of the cardiocycle occur (symmetry transformation). Violations of the golden relationship of the phases and the cardiocycle indicate damage to the heart. The magnitude of these deviations from the golden ratio depends on the severity of heart failure. Golden harmony in healthy people can be traced in the relations between the volumes of the left ventricle. These relationships are the ideal norm. Deviations in the relationship of volumes from golden ratio are a manifestation of pathology. Based on the principle of golden symmetry in healthy people, the normal EF is 62±3%, and not 50-80% as is accepted in practice. It is not an indicator of the norm. The mechanical activity of the heart is also determined by the laws of harmony. Pulse, diastolic and systolic blood pressure in healthy individuals are among themselves in the golden ratio (0,618). Violations of golden ratio are found in unstable forms of hypertension and damage to the heart muscle. Golden symmetry is the basis of the reference of the norm and the identification of pathologies of the human heart.
