Cardiac Autonomic Modulation in children and Preadolescents obese

To understand this problem, irstly we need to know that the sinoatrial node, responsible for generating electrical impulses that will turn into myocardial contraction is in luenced by the autonomic nervous system. The sympathetic nerves of the autonomic nervous system increase the blood pressure and heart rate (HR) and the parasympathetic nerves reduce the blood pressure and HR. So, the heart beats are adjusted, each moment, to the metabolic necessities. However, when dysautonomia exists, the HR and blood pressure can be altered and these alterations can be detected in the resting condition or during cardiac autonomic functional tests.
