The mechanisms controlling heart rate and blood pressure (BP) are quite complex. To some extent these hemodynamic variables are interrelated but observations from the Bogalusa Heart Study suggest different mechanisms are involved in their control and are influenced by ethnicity and gender. Heart rate seems to have a greater central autonomic control, being slower in black children than in white children,...
Heart rate, a hemodynamic parameter, is an important determinant of arterial wall stiffness. However, information on the relationship of heart rate to arterial wall thickness is inconsistent.
