Still's Murmur
Stills murmur (also known as vibratory murmur) is a common type of benign or "innocent" functional heart murmur that is not associated with any sort of cardiac disorder or any other medical condition. It can occur at any age although it is most common among children two to seven years of age and it is rare in adulthood. Still's murmur was initially described by Dr. George Frederic Still, England's first professor of childhood medicine at the Great Ormond Street Hospital for Children. In his pediatric textbook Common Disorders and Diseases of Childhood (published 1909) Dr. Still noted: ''“I should like to draw attention to a particular bruit which has somewhat of a musical character, but is neither of sinister omen nor does it indicate endocarditis of any sort. …its characteristic feature is a twangy sound, very like that made by twanging a piece of tense string... Whenever may be its origin, I think it is clearly functional, that is to say, not due to any organic diseas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Innocent Murmur
A functional murmur (innocent murmur, physiologic murmur) is a heart murmur that is primarily due to physiologic conditions outside the heart, as opposed to structural defects in the heart itself. Serious conditions can arise even in the absence of a primary heart defect, and it is possible for peripheral conditions to generate abnormalities in the heart. Therefore, caution should be applied to use of the terms "innocent" or "benign" in this context.Use of the term dates to the mid 19th century. Benign pediatric heart murmur Functional murmurs are an important consideration in the precordial examination of an infant or child. Presentation *Soft, less than 3/6 in intensity (although note that even when structural heart disease is present, intensity does not predict severity.) *Often position-dependent.

George Still
Sir George Frederic Still, KCVO (27 February 1868 – 28 June 1941) was an English paediatrician, author of five medical textbooks, and publisher of hundreds of papers. Still first described a form of juvenile idiopathic arthritis as well as the common functional Still's murmur, both of which bear his name. He was also one of the first to describe ADHD. He is frequently referred to as the "Father of British Paediatrics". Early life Still was born on 27 February 1868 in Highbury, London. He was the only boy of eight children born to George Still and Eliza Still (née Andrew). To distinguish him from his father, the junior Still was known by his middle name Frederic. Still was awarded a scholarship to attend the Merchant Taylors' School, a boys public school in London. He was from a working-class family who would otherwise have not been able to afford the fees. He was further awarded a scholarship to attend Gonville and Caius College, Cambridge. He matriculated in 1885 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Ormond Street Hospital For Children
Great Ormond Street Hospital (informally GOSH or Great Ormond Street, formerly the Hospital for Sick Children) is a children's hospital located in the Bloomsbury area of the London Borough of Camden, and a part of Great Ormond Street Hospital for Children NHS Foundation Trust. The hospital is the largest centre for child heart surgery in the UK and one of the largest centres for heart transplantation in the world. In 1962 they developed the first heart and lung bypass machine for children. With children's book author Roald Dahl, they developed an improved shunt valve for children with hydrocephalus, and non-invasive (percutaneous) heart valve replacements. They did the first UK clinical trials of the rubella vaccine, and the first bone marrow transplant and gene therapy for severe combined immunodeficiency.Breakthroughs It is closely associated with University College London (UCL) and in partnership with the UCL Great Ormond Street Institute of Child Health, which is adjac ...

Stethoscope
The stethoscope is a medical device for auscultation, or listening to internal sounds of an animal or human body. It typically has a small disc-shaped resonator that is placed against the skin, and one or two tubes connected to two earpieces. A stethoscope can be used to listen to the sounds made by the heart, lungs or intestines, as well as blood flow in arteries and veins. In combination with a manual sphygmomanometer, it is commonly used when measuring blood pressure. Less commonly, "mechanic's stethoscopes", equipped with rod shaped chestpieces, are used to listen to internal sounds made by machines (for example, sounds and vibrations emitted by worn ball bearings), such as diagnosing a malfunctioning automobile engine by listening to the sounds of its internal parts. Stethoscopes can also be used to check scientific vacuum chambers for leaks and for various other small-scale acoustic monitoring tasks. A stethoscope that intensifies auscultatory sounds is called a phon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supine Position
The supine position ( or ) means lying horizontally with the face and torso facing up, as opposed to the prone position, which is face down. When used in surgical procedures, it grants access to the peritoneal, thoracic and pericardial regions; as well as the head, neck and extremities. Using anatomical terms of location, the dorsal side is down, and the ventral side is up, when supine. Semi-supine In scientific literature "semi-supine" commonly refers to positions where the upper body is tilted (at 45° or variations) and not completely horizontal. Relation to sudden infant death syndrome The decline in death due to sudden infant death syndrome (SIDS) is said to be attributable to having babies sleep in the supine position. The realization that infants sleeping face down, or in a prone position, had an increased mortality rate re-emerged into medical awareness at the end of the 1980s when two researchers, Susan Beal in Australia and Gus De Jonge in the Netherlands, in ...

Heart Click
With newer, non-invasive imaging techniques, the origin of other, so-called ''adventitial sounds'' or heart clicks has been appreciated. These are short, high-pitched sounds. * The mitral valve in cases of mitral stenosis may open with an ''opening snap'' on the beginning of diastole. * Patients with mitral valve prolapse may have a mid-systolic click along with a murmur, referred to as apical late systolic murmur. Early systolic clicks may also be present in some patients. * Aortic and pulmonary stenosis Pulmonic stenosis, is a dynamic or fixed obstruction of flow from the right ventricle of the heart to the pulmonary artery. It is usually first diagnosed in childhood. Signs and symptoms Cause Pulmonic stenosis is usually due to isolated valvula ... may cause an ejection click immediately after S1.

Aorta
The aorta ( ) is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation. Structure Sections In anatomical sources, the aorta is usually divided into sections. One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) from the diaphragm to the aortic bifurcation. Another system divides the aorta with respect to its course and the direction of blood flow. In this system, the aorta starts as the ascending aorta, travels superiorly from the heart, and then makes a hairpin turn known as the aortic arch. Following the aortic a ...

Aortic Valve
The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta. It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets. The aortic valve is the last structure in the heart the blood travels through before stopping the flow through the systemic circulation. Structure The aortic valve normally has three cusps however there is some discrepancy in their naming. They may be called the left coronary, right coronary and non-coronary cusp. Some sources also advocate they be named as a left, right and posterior cusp. Anatomists have traditionally named them the left posterior (origin of left coronary), anterior (origin of the right coronary) and right posterior. The three cusps, when the valve is closed, contain a sinus called an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulmonary Valve
The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves, the other being the aortic valve. Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve. The closure of the pulmonary valve contributes the P2 component of the second heart sound (S2). The right heart is a low-pressure system, so the P2 component of the second heart sound is usually softer than the A2 component of the second heart sound. However, it is physiologically normal in some young people to hear both components separated during inhalation. Descript ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phonocardiogram
A phonocardiogram (or PCG) is a plot of high-fidelity recording of the sounds and murmurs made by the heart with the help of the machine called the phonocardiograph; thus, phonocardiography is the recording of all the sounds made by the heart during a cardiac cycle. Medical use Heart sounds result from vibrations created by the closure of the heart valves. There are at least two; the first (S1) is produced when the atrioventricular valves (tricuspid and mitral) close at the beginning of systole and the second (S2) when the aortic valve and pulmonary valve (semilunar valves) close at the end of systole. Phonocardiography allows the detection of subaudible sounds and murmurs and makes a permanent record of these events. In contrast, the stethoscope cannot always detect all such sounds or murmurs and provides no record of their occurrence. The ability to quantitate the sounds made by the heart provides information not readily available from more sophisticated tests and provides ...
