WitrynaIf afterload is increased (e.g., increasing aortic pressure by increasing systemic vascular resistance; red loop in figure), the stroke volume is reduced and the end-systolic volume increased. The increased end-systolic volume, however, leads to a secondary increase in end-diastolic volume because more blood is left inside the ventricle following ejection … Witryna14 The systemic vascular resistance (SVR) can be calculated when the CVP is simultaneously measured with standard methodologies The left-sided afterload is known as the systemic vascular resistance (SVR) Afterload is one of the primary determinants of myocardial oxygen demand.
