Heart Rate Recovery, Central Systolic Pressure, and Augmentation Index in Young Healthy Individuals.

Purpose: Measuring heart rate recovery (HRR) holds valuable cardiovascular information and requires minimal technical skill and cost. Understanding the associations between HRR and more robust cardiovascular indicators, such as central systolic blood pressure (CSBP), can provide valuable cardiovascular information with less involvement. CSBP is a strong predictor of certain cardiovascular diseases.

Impaired autonomic function in normotensive obese children.

Purpose: To evaluate baroreflex sensitivity and autonomic control in a cohort of normotensive obese (OB) children.

Method: A cross-sectional investigation, in which, baroreflex sensitivity and autonomic control were evaluated using transfer function and power spectral density analysis (PSDA) of the electrocardiogram and beat-to-beat blood pressures in normotensive OB children and normal weight normotensive controls. All methods used were noninvasive and data were captured while seated and at rest.
