David A. Rytand
David Abramson Rytand (November 4, 1909–November 23, 1991) was an American physician from California. He spent sixty-five years at Stanford University, first as a student and then as a faculty member. He was the chair of the department of medicine from 1954 to 1960. He was the editor of the ''Annual Review of Medicine'' from 1955 to 1963. Early life and education David Abramson Levy was born on November 4, 1909, in San Francisco, California, the only child of parents Hattie and Henri Garfield Levy, who were Jewish. He attended Stanford University, graduating with his bachelor's degree in 1929 and his Doctor of Medicine in 1932. By age twenty, he was using the name "David Rytand". It has been speculated that he changed his surname from "Levy" to "Rytand" due to discriminatory Jewish quotas that were in effect for many American universities' admission processes. "Rytand" is an anglicization of "Rechtandt". Henri Levy's grandfather Solomon Isaac Rechtandt immigrated from Pola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Association Of Physicians
The Western Association of Physicians (WAP) is a regional health association of academic physician-scientists. Over the years the society has grown to a membership of several hundred, including many distinguished academicians from diverse areas of medicine. History It was founded in 1955 by Robert Williams, the Chair of the Department of Medicine at the University of Washington, and other eminent physicians with the aim of establishing a western society analogous to the Association of American Physicians. Along with Williams, the founders of the WAP were Maxwell Wintrobe, Theodore Althausen, Joseph Ross, Clement Finch, David A. Rytand, John Lawrence, and Gordon Meiklejohn.

Stanford University School Of Medicine
Stanford University School of Medicine is the medical school of Stanford University and is located in Stanford, California. It traces its roots to the Medical Department of the University of the Pacific, founded in San Francisco in 1858. This medical institution, then called Cooper Medical College, was acquired by Stanford in 1908. The medical school moved to the Stanford campus near Palo Alto, California, in 1959. The School of Medicine, along with Stanford Health Care and Lucile Packard Children's Hospital, is part of Stanford Medicine. Stanford Health Care was ranked the fourth best hospital in California (behind UCLA Medical Center, Cedars-Sinai Medical Center, and UCSF Medical Center, respectively). History In 1855, Illinois physician Elias Samuel Cooper moved to San Francisco in the wake of the California Gold Rush. In cooperation with the University of the Pacific (also known as California Wesleyan College), Cooper established the Medical Department of the Univers ...

Atrioventricular Block
Atrioventricular block (AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired. Normally, the sinoatrial node (SA node) produces an electrical signal to control the heart rate. The signal travels from the SA node to the ventricles through the atrioventricular node (AV node). In an AV block, this electrical signal is either delayed or completely blocked. When the signal is completely blocked, the ventricles produce their own electrical signal to control the heart rate. The heart rate produced by the ventricles is much slower than that produced by the SA node. Some AV blocks are benign, or normal, in certain people, such as in athletes or children. Other blocks are pathologic, or abnormal, and have several causes, including ischemia, infarction, fibrosis, and drugs. __TOC__ Classification There are three types, or degrees, of AV block: ...

Mitral Annulus
The mitral valve (), also known as the bicuspid valve or left atrioventricular valve, is one of the four heart valves. It has two cusps or flaps and lies between the left atrium and the left ventricle of the heart. The heart valves are all one-way valves allowing blood flow in just one direction. The mitral valve and the tricuspid valve are known as the atrioventricular valves because they lie between the atria and the ventricles. In normal conditions, blood flows through an open mitral valve during diastole with contraction of the left atrium, and the mitral valve closes during systole with contraction of the left ventricle. The valve opens and closes because of pressure differences, opening when there is greater pressure in the left atrium than ventricle and closing when there is greater pressure in the left ventricle than atrium. In abnormal conditions, blood may flow backward through the valve ( mitral regurgitation) or the mitral valve may be narrowed (mitral stenosis). Rh ...

Diastolic Heart Murmur
Diastolic heart murmurs are heart murmurs heard during diastole, i.e. they start at or after S2 (heart sound), S2 and end before or at S1 (heart sound), S1. Many involve stenosis of the Heart valve#Atrioventricular valves, atrioventricular valves or regurgitation (circulation), regurgitation of the Heart valve#Semilunar valves, semilunar valves. Types * Early diastolic murmurs start at the same time as S2 with the close of the ''semilunar'' (aortic & pulmonary) valves and typically end before S1. Common causes include aortic or pulmonary regurgitation and left anterior descending artery stenosis. * Mid-diastolic murmurs start after S2 and end before S1. They are due to turbulent flow across the ''atrioventricular'' (mitral & tricuspid) valves during the rapid filling phase from mitral or tricuspid stenosis. * Late diastolic (Presystolic murmur, presystolic) murmurs start after S2 and extend up to S1 and have a crescendo configuration. They can be associated with Heart valve#Atri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
