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 ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
Left-sided heart failure may be present with a reduced ejection fraction or with a preserved ejection fraction. [10] Heart failure is not the same as cardiac arrest, in which blood flow stops completely due to the failure of the heart to pump. [12] [13] Diagnosis is based on symptoms, physical findings, and echocardiography. [6]
An 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 , [ 1 ] ventricle , [ 2 ] gall bladder, [ 3 ] or leg veins, [ 4 ] although if unspecified it usually refers to the left ...

Whilst left-sided heart failure will reduce cardiac output to the systemic circulation, the initial symptoms often manifest due to effects on the pulmonary circulation. In systolic dysfunction, the ejection fraction is decreased, leaving an abnormally elevated volume of blood in the left ventricle.
People who have experienced heart palpitations describe their symptoms in interesting and wide-ranging ways, says Dr. Edo Paz, a cardiologist at White Plains Hospital in New York and senior vice ...
