WebIn cardiovascular physiology, stroke volume (SV) is the volume of blood pumped from the left ventricle per beat. Stroke volume is calculated using measurements of ventricle volumes from an echocardiogram and … Un aumento del postcarico (che corrisponde alla pressione aortica durante la sistole) riduce il volume sistolico. Sebbene esso non influenzi il volume sistolico nei soggetti sani, un postcarico aumentato ostacola l'eiezione del sangue da parte dei ventricoli, determinando una riduzione del volume sistolico. Un aumento del postcarico è presente, ad esempio, nella stenosi aortica e nell'ipertensione arteriosa.
