| ventricular filling pressure | The pressure in the ventricle as it fills with blood, ordinarily equivalent to the mean atrial pressure when there is no A-V valvular gradient. Atrial pressure can be used in place of transmural pressure because pericardial pressure usually varies between -2 and +2 mm Hg and hence is negligible. During cardiac tamponade, pericardial and atrial pressures equilibrate so that transmural pressure is zero and the high atrial presures cannot be "filling" pressures. (05 Mar 2000) |
