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.
9. Regulation in the disease
The total power of regulation and disease
In HRV, the total power of the regulation estimates through TP.
Everything is good in moderation. With a total power of regulation too.
Excessive regulation manifests with hyperreactive distress – the danger of storms, disasters with high arterial pressure and heart rate, various kinds of arrhythmias, up to and including life-threatening.
Underregulation is a sign of decreased control over the disease.
The disease develops slowly.
Stress is hyporeactive but has effects like hyperreactive one.
Depletion of regulation with shallow values of its power is considered to be a sure sign of impending sudden death.
Emotional stress plays a much more significant role in death from cancer and heart disease than smoking.
Among those unable to control stress, the death rate is 40% higher against those who have learned to manage it.
Bronchial asthma and HRV
The patient is 55 years old. Persistent severe bronchial asthma. Exacerbation of moderate severity. 4 st. Systemic lymphostasis. Chronic lymphovenous insufficiency on the background of the post-thrombophlebitic syndrome of the lower extremities. Arterial hypertension 2 st. CHF 2A. FC 2. Metabolic obesity of a mixed type of 2 severity.
Above HRV before treatment in the active orthostatic test. Low TP with a predominance of VLF and LF. They have a perverted orthostatic reaction.
Below HRV before and during treatment. On the background of treatment with seretid 250 mcg: 1 inhalation 2 times a day, salbutamol during asthma attacks, hydrochlorothiazide 25 mg x 3 p / day, aspirin 325 mg per day activation of the sympathetic nervous system.
Pneumonia and HRV.
The patient is 22 years old. Left-sided lower lobe pneumonia, BF 0. At the onset of the disease, BP 100/70 mm Hg, HR 86 beats min, after recovery – BP – 120/80 mm Hg, HR is 68 beats/min.
On the left HRV in the first days of the disease at a height temperature and the right – after recovery. Initially a sharp decrease in the power of the spectra of all links of HRV, the predominance of the high-frequency connection with the LF / HF ratio of 0.6 as a result of shortness of breath. After recovery, a significant increase (11 times) in the TP of the HRV spectrum with a predominant increase in the power of the spectra of the low-frequency and mid-frequency components, LF/HF – 3.0.
