WebStroke volume is defined as end-diastolic volume minus end-systolic volume; cardiac output is the stroke volume times the heart rate. The left ventricular pressure–volume loop is drawn and the work of the heart is considered as the area within the loop. Total cardiac work, however, includes the kinetic work, PV work, and gravitational work. WebOther echocardiographic findings suggestive of HEPEF include an left ventricular end-diastolic index <76 mL/min 2, a LA volume indexed to body surface area <29 mL/m 2 without AF, and a left ventricular mass index <96 g/m 2 in women and <113 g/m 2 in men. A left ventricular end-diastolic volume index >76 mL/min is suggestive of a high-output state.

WebStroke Volume is the difference between end diastolic volume (EDV) and end systolic volume (ESV). ESV can be affected by 4 factors; preload, afterload, contractility, and … WebThe end diastolic volume is determined primarily by venous filling pressure. Because the ventricle is very compliant, small changes in venous filling pressure have a major effect … download manager nhkg n
