ventricular ejection fraction (LVEF), is calculated by dividing the volume of blood pumped from the left ventricle per beat (stroke volume) by the volume...

but particularly the less vertical fraction slash. The variant "oblique stroke" was increasingly shortened to "stroke", which became the common British...

stroke (UK); and the fraction bar, solidus, or fraction slash. In typography, fractions stacked vertically are also known as "en" or "nut fractions"...

ejection fraction, which is stroke volume divided by end-diastolic volume. Because stroke volume decreases in certain conditions and disease states, stroke volume...

A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft...

Stroke (also known as a cerebrovascular accident (CVA) or brain attack) is a medical condition in which poor blood flow to the brain causes cell death...

major measurements obtained by cardiac ventriculography are: Ejection Fraction Stroke Volume Cardiac Output These three measurements share a commonality...

Stroke volume (= end-diastolic volume − end-systolic volume) Ejection fraction (= stroke volume / end-diastolic volume) Cardiac output is mathematically `...

heart failure may be present with a reduced ejection fraction or with a preserved ejection fraction. Heart failure is not the same as cardiac arrest, in...

Depending on the design, pump guns can be either single-stroke or multi-stroke. In single-stroke pneumatic air guns (also known as "single pump") a single...

cycle, and also to allow calculation of left ventricular ejection fraction, stroke volume, and cardiac output. SPECT can be used to complement any gamma...

Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood...

physiologically relevant hemodynamic parameters such as stroke volume, cardiac output, ejection fraction, myocardial contractility, etc. can be determined from...

influenced the European form, a two-stroke form consisting of a horizontal upper stroke joined at its right to a stroke going down to the bottom left corner...

fraction, which is the percentage of the left ventricular stroke volume that regurgitates into the left atrium.[citation needed] regurgitant fraction...

of blood regurgitated into a cardiac chamber divided by the stroke volume. This fraction affords a quantitative measure of the severity of the valvular...

intermittent, such as the more familiar two-stroke and four-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel rotary...

Embolic stroke of undetermined source (ESUS) is an embolic stroke, a type of ischemic stroke, with an unknown origin, defined as a non-lacunar brain infarct...

up to 67%. Clinical trials show that istaroxime improves ejection fraction, stroke volume and systolic blood pressure, while also enhancing ventricular...
