Normal lv function
WebAn ejection fraction (EF) is the volumetric fraction (or portion of the total) of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat).It can refer to the cardiac atrium, ventricle, gall bladder, or leg veins, although if unspecified it usually refers to the left ventricle of the heart. EF is widely used as a measure of the … WebIn normal, resting, supine man the ventricular function curve is at its peak at a left ventricular end-diastolic pressure of approximately 10 mm Hg. Below this point is a strong direct relation between filling pressure and stroke work, while at higher filling pressures, a plateau occurs. Limitation of ventricular response is related to a ...

Previous work has highlighted the need for technique specific normal ranges. The purpose of this study was therefore to establish normal ranges of LV volume and mass for the …
WebIntroduction. Hypertension is one of the major risk factors for left ventricular (LV) diastolic dysfunction (DD) and heart failure with preserved ejection fraction (HFpEF). 1 Some previously documented sex-specific differences in structural and functional parameters of the heart and arteries may influence LV diastolic function in men and women. 2 … WebLV Systolic Function in Obesity. LV systolic function, determined using LV ejection phase indices such as LV fractional shortening or LV ejection fraction (LVEF), has been less extensively studied than LV mass and LV diastolic function in obese patients [3–5,7,37–41]. In most obese subjects LV systolic function is normal or supranormal [3 ...
