Hemodynamic Response to Dynamic Exercise in Adolescence

It is now generally recognized that tests of exercise stress are useful in diagnosis of coronary artery disease, determination of the appropriate exercise allowance and evaluation of the efficacy of medical and surgical treatment. However, little information is available on hemodynamic effects during exercise in children with congenital heart disease (CHD) before or after operation. Exercise is important in management and rehabilitation of children with cardiac diseases. Moreover, it is very important to determine the hemodynamic responses to training programs in children at school using noninvasive methods. For this reason, I studied the systolic time interval (STI), the stroke volume (SV) as a percentage of the initial value (% SV) and the cardiac output (CO) as a percentage of the initial value (% CO) by the impedance method and the working capacity during bicycle ergometer exercise.
