Polygraphic records of ECG, PCG, carotissphygmogram and apexcardiogram were performed and 16 systolic and diastolic intervals were taken in 86 patients with hypertonic disease, distributed according to the stage of the disease according to Mjassnikov classification as well as in 62 subjects with intact hearts. A lengthening of asynchronous contraction was established as well as of the isovolumetric contraction, pre-blood driven period, isovolumetric relaxation and shortening of the left-ventricle time of blood driving, the ratio pre-blood driven peroid/left ventricle time of blood driving showing the most pronounced changes. Regression and correlation analysis in the comparison of those changes in the intervals with a means blood pressure in patients from the three stages of hypertonic disease, show that the best correlation is obtained in the patients from the III stage. The results obtained are discussed and a conclusion is drawn that the ratio pre-blood driven period/left ventricle time of blood driving is with the highest practical importance from the systolic and diastolic intervals in the assessment of the adequacy of the left-ventricle compensation.
