Ejection fraction

Index Ejection fraction

An ejection fraction (EF) is the volumetric fraction of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat). [1]

Blood

Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

Cardiac cycle

The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next.

Cardiac muscle

Cardiac muscle (heart muscle) is one of the three major types of muscle, the others being skeletal and smooth muscle.

Cardiac ventriculography

Cardiac ventriculography is a medical imaging test used to determine a patient's cardiac function in the right, or more typically, left ventricle.

Cardiomyopathy

Cardiomyopathy is a group of diseases that affect the heart muscle.

Circulatory system

The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.

Echocardiography

An echocardiogram, often referred to as a cardiac echo or simply an echo, is a sonogram of the heart.

End-diastolic volume

In cardiovascular physiology, end-diastolic volume (EDV) is the volume of blood in the right and/or left ventricle at end load or filling in (diastole) or the amount of blood in the ventricles just before systole.

End-systolic volume

End-systolic volume (ESV) is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole.

Fraction (mathematics)

A fraction (from Latin fractus, "broken") represents a part of a whole or, more generally, any number of equal parts.

Gated SPECT

Gated SPECT - A nuclear medicine imaging SPECT (Single Photon Emission Computed Tomography) procedure where the ECG (Electrocardiogram) guides the acquisition so that the resulting set of SPECT images shows the heart as it contracts over the interval from one R wave to the next.

Gold standard (test)

In medicine and statistics, gold standard test is usually diagnostic test or benchmark that is the best available under reasonable conditions.

Heart

The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.

New!!: Ejection fraction and Heart · See more »

Heart failure

Heart failure (HF), often referred to as congestive heart failure (CHF), is when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs.

Magnetic resonance imaging

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease.

New!!: Ejection fraction and Magnetic resonance imaging · See more »

Myocardial infarction

Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.

Nuclear medicine

Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease.

Percentage

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

New!!: Ejection fraction and Percentage · See more »

Pulmonary circulation

The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle of the heart, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart.

Radionuclide angiography

Radionuclide angiography is an area of nuclear medicine which specialises in imaging to show the functionality of the right and left ventricles of the heart, thus allowing informed diagnostic intervention in heart failure.

Ratio

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second.

Stroke volume

In cardiovascular physiology, stroke volume (SV) is the volume of blood pumped from the left ventricle per beat.

Ventricle (heart)

A ventricle is one of two large chambers in the heart that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs.

William Harvey

William Harvey (1 April 1578 – 3 June 1657) was an English physician who made seminal contributions in anatomy and physiology.
