Description
Summary:Regulation of the circulatory system in hypertensive crises was studied using mathematical analysis of the cardiac rhythm. The study involved 166 patients from age 29 to 73 years with hypertension stage II–III. The cardiac rhythm variability was assessed for 10-min intervals by parameters of the regulatory system activity (according to R.M. Baevskiiet al.). In hypertensive crisis, the cardiac rhythm variability was decreased, and the activity of systems regulating blood circulation was increased, compared to both the normal and the crisis-free period. Therefore, the determination of parameters of cardiac rhythm variability has an additional diagnostic value. Changes in these parameters in hypertensive crisis depend on the duration of hypertension, the patients’ age, and dysfunction of target organs. Changes in the cardiac rhythm variability persisted after normalization of arterial pressure in the postcrisis period, and this indicates that the patients’ condition was not stabilized during hospital treatment and prolonged supervised hypotensive therapy was required.
