HRV analysis helps us quantify the balance between sympathetic and parasympathetic nervous system activity. It does so by measuring the variations in time intervals between consecutive heartbeats, which reflect the influence of the autonomic nervous system on heart rate modulation. High HRV indicates a healthy balance between the two branches, indicating resilience and adaptability to stress, while low HRV suggests an imbalance and reduced ability to cope with stress.

Physical Stress Assessment:
During physical stress, such as intense exercise or physical exertion, HRV analysis can provide insights into the body's response to the increased demand. It allows us to assess the body's capacity to adapt to exercise and recover efficiently. Individuals with higher HRV during physical stress typically exhibit better cardiovascular fitness and resilience. Monitoring HRV can aid in optimizing training regimens, preventing overtraining, and identifying signs of fatigue or potential health issues.

Mental Stress Assessment:
Mental stress, including psychological or emotional stressors, can significantly impact our well-being. HRV analysis serves as a useful tool for objectively quantifying the body's response to mental stress. Studies have shown that prolonged mental stress can lead to reduced HRV, indicating an imbalance in the autonomic nervous system and increased sympathetic dominance. Monitoring HRV in individuals experiencing chronic stress can help identify the need for stress management techniques, lifestyle modifications, and relaxation interventions.

The Stress Index indicator is calculated based on the analysis of the distribution graph of cardiointervals-a variational bullet diagram. Activation of the central circuit, increased sympathetic regulation during mental or physical exertion is manifested by stabilization of the rhythm, a decrease in the spread of duration of cardiac intervals, an increase in the number of intervals of the same type in duration. The stress index or the value of the stress indicator reflects the level of psychoemotional and physical stress. This parameter characterizes the state of the regulatory centers of the cardiovascular system. The index norm is the index value from 50 to 200. With physical exertion, chronic fatigue and a decrease in the reserves of the body with age, the index ranges from 150 to 500. With angina pectoris, psychophysiological fatigue, significant psychological and emotional stress, the stress index reaches values from 500 to 800. An index above 800 indicates a significant violation of regulatory mechanisms. In the pre-infarction state of the patient, a stress index exceeding 900 units may be observed.

The information and analytical module of the LifePulsePro system is able to detect some manifestations of mental stress. Interpreting the HRV test results allows us to indirectly determine the rhythms of the brain.
