Specificity of the effect of double fractures of the rhythmogram on the daily variability of the sinus rhythm in patients with pulmonary and arterial hypertension
Introduction. In contrast to coronary heart disease (CHD), heart failure and a number of other diseases, in arterial and pulmonary hypertension, the deterioration of the functional state of the patient is often not accompanied by a decrease in the parameters of his sinus rhythm variability (SRV) for...

In the analysis of daily SRV, a modification of the SRV analysis method developed at the National Medical Research Center of Cardiology, taking into account the presence of DFR, was used. Results. It is shown that DFR reflects the processes of regulation of the sinus rhythm, which are affected differently by CHD and hypertension. In CHD, the frequency of DFR and its effect on the daily SRV significantly decreases (compared to the norm). With hypertension, the frequency of the appearance of DFR increases; there is a clear trend towards a decrease in SRV in comparison with the norm in the areas without DFR; in areas with DFR, this trend is less pronounced or absent, and at ages over 50 years, SRV increases. Conclusion. When studying the daily SRV of patients with arterial and idiopathic pulmonary hypertension, it is necessary to take into account the effect of DFR on the increase in SRV.Alexander V.

Introduction. In contrast to coronary heart disease (CHD), heart failure and a number of other diseases, in arterial and pulmonary hypertension, the deterioration of the functional state of the patient is often not accompanied by a decrease in the parameters of his sinus rhythm variability (SRV) for long periods of time. Moreover, an increase in age and an increase in blood pressure in patients with hypertension may lead not to a decrease, but to an increase in the parameters of daily SRV. It is noted that with hypertension on the sinus rhythm, the number of so-called double fractures of the rhythmogram (DFR) sequences of RR intervals short-long-short-long becomes greater, which can greatly affect the daily SRV.
Aim. To study the specifics of the effect of DFR on daily SRV in arterial and pulmonary hypertension.
Materials and methods. 300 Holter ECG records were analyzed, including 67 records of healthy persons, 20 records of CHD patients with CAG-confirmed vascular damage, 126 records of patients with arterial hypertension and 87 records of patients with idiopathic pulmonary hypertension. In the analysis of daily SRV, a modification of the SRV analysis method developed at the National Medical Research Center of Cardiology, taking into account the presence of DFR, was used.
