Stroke volume variability …
Web29 ago 2024 · Stroke volume is the amount of blood pumped out of the left ventricle in one heartbeat. Factors that affect stroke volume are cardiac preload, afterload, and contractility. The normal range of stroke volume (SV) is 50 – 100 ml. Stroke volume is calculated using the following formula. WebAbstract —Ratio of stroke volume (SV, M-mode echocardiography) to pulse pressure (PP) has been proposed as an estimate of total arterial compliance and has been shown to be related to body size, age, and heart rate in normal adults.
