The transition to personalized (individualized) medicine requires the development of new objective methods for recording parameters of the functions of the human organism. In particular, we are talking about the parameters of the cardiovascular system. Therefore, the purpose of this research is to create new methods for assessing the state of the human cardiovascular system in the North of the Russian Federation. Object and methods: a group of women (15 people, average age 29 years) for whom 15 parameters of the cardiovascular system were recorded 15 times for each subject using the device «Elox-01C». First, registration was carried out in a calm state (sitting), and then after 30 squats in 1 minute. For each subject, the parameters of quasi-attractors (area S) were calculated in the two-dimensional phase state space (for cardiointervals), and then in the two-dimensional phase space (before and after and load). It is proved that the areas of quasiattractors in the two-dimensional (for cardiointervals) and two-dimensional phase spaces for the neuromuscular system are significantly different for each subject and for the whole group of 15 people. It is advisable to use the method for calculating the area S for quasi-attractors in two-dimensional phase spaces of state both for individual differences (between subjects) and for differences in the functional states of the human organism, a whole group of subjects. These parameters are an individual characteristic of each patient in medicine, which is advisable to use in personalized (individualized) medicine.
