Tumors expressing the author's religious beliefs, others prefer to interpret ociucvic qoi, in div. 26 it seems that the ventricle at end-diastole and end-systole and subsequently pulmonary vascular disease. (surgicalimpex.com)
The pause or interval between the systole or contraction, and the diastole or dilatation of the heart. (byu.edu)
Low-frequency sounds include the third heart sound (S3, which may be physiologic or pathologic), associated with early ventricular filling, and the fourth heart sound (S4), associated with the atrial systole in late diastole. (medilib.ir)
A second hypothesis suggests that the principal high-frequency elements of S1 are related to movement and acceleration of blood in early systole, and are influenced by the peak rate of rise of left ventricular (LV) systolic pressure (dP/dt), which is a measure of contractility and ejection of blood into the root of the aorta [ 14 ]. (medilib.ir)
We have found, in in vivo studies, that blood pressure has a strong relation to the antegrade longitudinal displacement in early systole. (bvsalud.org)
Contraction3
During ventricular systole (contraction) the pressure in the ventricles rises above that in the atria and the valves shut for a short while preventing backflow of blood. (pharmacyscope.com)
Ventricles contact forcing blood up through the semi lunar valves and into the aorta and pulmonary artery, -Force of contraction closes the atrioventricular valves preventing blood from flowing back into the aorta. (printableflashcards.net)
Lub' is due to contraction of ventricles and 'dub' is due to closer of auricle valves. (cbsencertsolutions.com)
Atrial4
The posterior leaflet is also divided into 3 distinct scallops with the scallop closest to the left atrial appendage and the anterolateral commissure named the P1 segment. (echoboardsacademy.com)
During ventricular systole, the mitral valve closes and prevents backflow to the LA. The normal function of the mitral valve depends on its 6 components, which are (1) the left atrial wall, (2) the annulus, (3) the leaflets, (4) the chordae tendineae, (5) the papillary muscles, and (6) the left ventricular wall (see the image below). (medscape.com)
[ 2 ] Each leaflet has an atrial and a ventricular surface. (medscape.com)
These 2 zones are separated by a prominent ridge on the atrial surface of the leaflet, which is the line of the leaflet closure. (medscape.com)
Mitral valve3
Because of these differences, the mitral valve annulus should be measured at end-systole in both the ME commissural and LAX views. (echoboardsacademy.com)
[ 6 ] During systole or mitral valve closure, the rough zone of the anterior leaflet will appose to the rough zone of the posterior leaflet. (medscape.com)
Ventricular4
The annulus will decrease in the area as it descends towards the left ventricular apex during systole. (echoboardsacademy.com)
0.0001) in a model that included age, gender, body mass index, body surface area, blood pressure levels, and left ventricular mass index as confounding variables. (researchgate.net)
We also found that the peaks of the ventricular inflow and outflow waves as well as the peaks of the regurgitation waves are all correlated positively with body surface area. (bvsalud.org)
[ 6 ] The rough zone is thick and has chordae tendineae insertions on the ventricular surface. (medscape.com)
Mathbb1
For an arbitrary $H$ with at least one generator of order $\geq 3$, we derive a computable optimal upper bound for the restriction $\mathrm{sys} : \mathrm{Fix}(H) \to \mathbb{R}^+$ of the systole function. (arxiv.org)
Ventricles1
The valves, between the atria and ventricles, open and close passively according to changes in pressure in the chambers. (pharmacyscope.com)
Systolic1
The non-compliant vessels do not stretch in response to the systolic pressure, and thus the pressure rises rapidly at the beginning of systole, resulting in a steep systolic upstroke.Because of the poor compliance, a powerful reflected wave is sent back to the aortic root, which when added to the systolic effort of the ventricle makes for a high peak systolic pressure. (derangedphysiology.com)
Hyperbolic3
Of all genus 2 {\displaystyle 2} hyperbolic surfaces, the Bolza surface maximizes the length of the systole (Schmutz 1993). (wikipedia.org)
This is a quasi-Fuchsian manifold: it's a basic kind of 3 manifold homeomorphic to the product of a surface and an interval together with a (non unique) choice of hyperbolic metric. (github.io)
Togther with Prof. S. Kojima of TITEC we are working on applying converegence results for quasi-Fuchsian manifolds and Teichmueller theory to get information about closed hyperbolic manifolds. (github.io)
Pressure4
The valves with inertia closing elements are opened and closed by the pressure differential which builds up a force moving the ball-type closing element or a moment which overturns the disc-type closing element. (justia.com)
In response to the progressive narrowing of the aortic valve opening, the LV myocardium becomes hypertrophic in order to generate increased pressure during systole and thus force blood past the obstruction. (medscape.com)
Genus1
The spectral theory of the Laplace-Beltrami operator acting on functions on the Bolza surface is of interest to both mathematicians and physicists, since the surface is conjectured to maximize the first positive eigenvalue of the Laplacian among all compact, closed Riemann surfaces of genus 2 {\displaystyle 2} with constant negative curvature. (wikipedia.org)
Affine3
The Bolza surface is the smooth completion of the affine curve. (wikipedia.org)
More than 10 years ago, I classified the affine surfaces that can isometrically deformed (with respect to the induced Blaschke metric) while preserving their affine mean curvature in a 3-dimensional family (the maximum dimension possible), showing that they depend on 2 functions of 1 variable in Cartan's sense. (duke.edu)
I'll explain these results and use them to show how the classical problem of determining the affine surfaces with constant affine mean curvature and constant Gauss curvature of the Blaschke metric can be explicitly integrated, which, heretofore, was unknown. (duke.edu)
Muscles2
The valves are prevented from opening upwards into the atria by tendinous cords, chordae tendineae, which extend from the inferior surface of the cusps to little projections of myocardium covered with endothelium, called papillary muscles. (pharmacyscope.com)
Close to the muscles, this helps with blood flow as the muscle contacts. (printableflashcards.net)
Leaflets3
Although they are shaped quite differently, the two leaflets have similar surface areas. (echoboardsacademy.com)
The posteromedial papillary muscle is close to the interventricular septum and supports the posteromedial segments of the leaflets, Carpentier A3/P3, and A2/P2 s callops. (echoboardsacademy.com)
[ 2 ] The annulus functions as a sphincter that contracts and reduces the surface area of the valve during systole to ensure complete closure of the leaflets. (medscape.com)
Capillaries4
Network of capillaries are found in tissue that increases surface area, these networks are where metabolic rate happens. (printableflashcards.net)
The total surface area of capillaries is the largest even though the diameter of the capillaries is the smallest. (stretchysuzies.com)
As the capillaries becomes venules, the diameter increases while the total surface area decreases. (stretchysuzies.com)
Capillaries carry blood very close to the cells of the tissues of the body, in order to exchange gases, nutrients and waste products. (stretchysuzies.com)

Curves2
When I gave a talk* in this seminar about these results on September 10, 2013, I only knew that these surfaces corresponded to pseudoholomorphic curves in a certain almost-complex surface. (duke.edu)
However, I have recently shown that the structure equations for these mysterious surfaces can be interpreted as describing holomorphic Legendrian curves in CP^3 subject to a natural positivity condition, and the integration corresponds to a flat sp(2,R) connection, i.e., they can be interpreted as a Lax pair, but of a very special kind, for which the integration can be effected explicitly. (duke.edu)
Ossian Bonnet (1819-1892) classified the surfaces in Euclidean 3-space that can be isometrically deformed without changing the mean curvature function H, showing that there are two types: the surfaces of constant mean curvature and a 4-dimensional 'exceptional family' (with variable mean curvature) that are now known as Bonnet surfaces.

The Fuchsian group Γ {\displaystyle \Gamma } defining the Bolza surface is also a subgroup of the (3,3,4) triangle group, which is a subgroup of index 2 in the ( 2 , 3 , 8 ) {\displaystyle (2,3,8)} triangle group. (wikipedia.org)
It is possible to obtain an equivalent closed form of the systole directly from the triangle group. (wikipedia.org)
In particular, we will discuss the boundaries of a type of group which is built up from surface groups, graph-Kleinian groups. (temple.edu)
