Hemodynamic and Ventilatory Effects of Exercise in the Upright Position in Patients with Left-to-Right Shunts

Hemodynamic and Ventilatory Effects of Exercise in the Upright Position in Patients with Left-to-right Shunts.

THE behavior of the pulmonary vascular resistance during exercise in patients with ventricular septal defect or patent ductus arteriosus influences the magnitude and direction of tlhe shunt of blood across the defect and also may provide clues concerning the genesis of the pulmonary hypertension often seen in large defects. In previous studies,1' 2 pulmonary artery wedge pressure had not been d...

Since any attempt to understand the disability of such patients depends on these, we have attempted a further investigation into the changes occurring during exercise. This paper deals with the hemodynamics, and a following communication is...
