There is examine a character of change of brain bioelectric activity and polygraphic indicators at sessions of biofeedback by heart rhythm variability parameters (HRV-biofeedback) in 15-17 years adolescents who have different variants of cardiac autonomic nervous system tone. It is taped, that adolescents with cardiac balanced tone have more intensive optimization of functional brain activity in comparison with adolescents who have cardiac sympathetic tone - increase on alpha-activity and theta-activity depression in electroencephalogram structure. There were optimization of neurodynamic processes and most expressed stabilization of the hemodynamics indicators in adolescents with cardiac sympathetic tone after HRV-biofeedback training.
对15至17岁具有不同心脏自主神经系统张力变体的青少年进行了通过心律变异性参数（心率变异性生物反馈，HRV-生物反馈）进行生物反馈治疗时脑生物电活动和多导记录指标变化特征的研究。记录显示，与具有心脏交感神经张力的青少年相比，具有心脏平衡张力的青少年大脑功能活动的优化更为强烈——脑电图结构中α活动增加，θ活动减少。在HRV-生物反馈训练后，具有心脏交感神经张力的青少年的神经动力学过程得到优化，血液动力学指标的稳定最为明显。
