MeSH definition : The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure
catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging
techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an
estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right
atrial pressure).;
