Enlargement of the chambers of the heart, typically because of diseases of the heart valves or cardiomyopathy. It may result in congestive heart failure.Medical Dictionary, © 2009 Farlex and Partners Want to thank TFD for its existence? Tell a friend about us, add a link to this page, or...
1.PhysiologyThe normal rhythmically occurring relaxation and dilatation of the heart chambers, especially the ventricles, during which they fill with blood. 2.The lengthening of a normally short syllable in Greek and Latin verse. [Greekdiastolē,dilation, separation, fromdiastellein,to expand:dia-,...
The local signs of valvular disease may be absent or present. Signs of cardiac enlargement with dilatation of the chambers of the heart are present and may usually be recognized. These phenomena are usually present in varying degrees of severity, in an incompetent heart. When due to intrinsic ...
16.The two upper receiving chambers of the heart are called the right and left ___. 答案: atria 17.The mitral valve has ___ cusps or leaflets that open and close. 答案: two 18.___ refers to the contraction phase of the ventricles in the heartbeat cycle. 答案: Systole 19.___ ...
The cardiovascular system (CVS) is made up of the heart, blood vessels, and blood. The fundamental function of CVS is to transport substances to and from all parts of the body. The heart is the major pumping organ, pressurizing blood for circulation thro
systolic pressure- the blood pressure (as measured by a sphygmomanometer) during the contraction of the left ventricle of the heart diastolic pressure- the blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood ...
Both heart sounds are poorly heard or are actually decreased in intensity in general obesity, general debility, degeneration or dilatation of the heart, pericardial or pleural effusion, and emphysema. The reduplication of heart sounds is probably due to a lack of synchronous action in the valves ...
specific properties of the myocardial fibers, for example, the interdependence between cardiac rhythm and the force of contraction of cardiac fibers and the interdependence between the contractile energy of the fibers and the extent of the dilatation of the heart during diastole (law of the heart)...
However, with a sustained hemodynamic load, maladaptive hypertrophy will proceed, which is associated with dilatation of the heart chambers, accumulation of collagen in the extracellular matrix (interstitial fibrosis), loss of cardiac myocytes (apoptosis), and cardiac dysfunction (Fig. 1). Consequently...
Figure 4. The “W” flows inside the heart (yellow lines). Apart from the different flow vortices that are generated inside the heart due to the different morphology of the cardiac chambers, this behavior could be considered a remnant of the original linear flow in the cardiac straight tube...
