Heart rate variability: for real doctors. Translation from the Russian version of the book, published at Kharkiv, 2010, 131 p.
The basics and practice of the clinical use of the technology of heart rate variability are outlined for doctors of all specialties and students of medical faculties of universities.
Tests with metronomic breath
Tests with modulated (metronomic) breath make it possible to assess the quality of connections with the respiratory center and, through it, other regulation links with parasympathetic nerves, or rather, their nuclei. It means the state of the nuclei of the respiratory center (inhalation, exhalation, breath retention between inhalation and exhalation, breath retention between exhalation and inhalation) and the quality of their connections. On the one hand, these are the connections between the nuclei of the respiratory center, on the other, the connections of these nuclei with the nuclei of the vagus nerves, and, from the third, with higher regulatory structures frames, including auditory and/or visual integration, including their combination. The sound and light metronomes are used in different relationships. These metronomes are usually included in the software In the basal conditions, the study is first carried out with spontaneous breathing, and then with one or several modulation frequencies selected. The most frequently used modulated frequencies correspond to the frequency of spontaneous respiration of the patient. For this, during the period of registration of HRV indices in basal conditions without attracting the attention of the patient, his respiratory rate per minute (RR) is calculated. As soon as the patient notices that you control his RR, he will immediately “take” it under his control, and it will cease to be arbitrary.
Possible (incomplete) modulated breathing test options:
– different frequencies of metronomic respiration;
– different ratios of inspiration and expiration times at the same frequency of metronomized respiration;
– metronomic breathing with a light metronome;
– metronomic breathing with a sound metronome;
– metronomic breathing with a double (light and sound) metronome;
– variants of other forms breathing with different rules
changes in (instantaneous) frequency and/or depth of inhalation and exhalation during breathing.
