PHYSIOLOGICAL EFFECTS OF PULMONARY HYPERTENSION ON CARDIAC FUNCTION
The right and left sides of the heart are functionally integrated by their anatomical contiguity. There is continuity between their free walls, they share a common wall (the intraventricular septum), and they are covered by the pericardium. When pulmonary vascular resistance is normal, the right ventricle serves as a capacitance chamber, performing only minimal contractile work. It compensates ineffectually for acute rises in pulmonary artery pressure, and acutely it can only generate a mean pressure of 40 mm Hg. Acute elevations of right ventricular pressures also interfere with left ventricular performance, presumably owing to a shift in the intraventricular septum to the left. Chronic elevations of pulmonary artery pressure cause gradual hypertrophy of the right ventricle, which eventually allows it to generate pressures equal to those in the left ventricle.
