Cardiopulmonary Exercise Testing and Interpretation of the Major Related Variables in Patients with Congenital Heart Disease

Ohuchi H

  • KMID: 1852883
  • J Korean Pediatr Cardiol Soc.
  • 2006 Sep;10(3):253-259.
Cardiac surgery significantly influences cardiac autonomic nervous activity (CANA) and pulmonary function, resulting in abnormal cardiopulmonary responses during exercise testing in postoperative patients with congenital heart disease (CHD). In addition,...
