High afterload means
WebAfterload can also be described in terms of wall tension, which means that the force is adjusted for surface area. Afterload depends on the thickness of the myocardium. Individuals with high blood pressure (high … WebThe pulmonary wedge pressure ( PWP ), also called pulmonary arterial wedge pressure ( PAWP ), pulmonary capillary wedge pressure ( PCWP ), pulmonary artery occlusion pressure ( PAOP ), or cross-sectional pressure, is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.
