The LVAD is the most common device applied to a defective heart (it is sufficient in most cases; the right side of the heart is then often able to make use of the heavily increased blood flow), but when the pulmonary arterial resistance is high, then an (additional) right ventricular assist device (RVAD) might be necessary to resolve the ...
Pump thrombosis is defined as a specific case of a major device malfunction. In turn, device malfunction is as defined by Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) as a failure of one or more of the components of the mechanical circulatory support systems which either directly causes or could potentially induce a state of inadequate circulatory support (low ...
LVAD may stand for: Left ventricular assist device, see Ventricular assist device; Low-Velocity Airdrop, see HALO/HAHO This page was last edited on 28 ...
Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...
The EF of the right heart, or right ventricular ejection fraction (RVEF), is a measure of the efficiency of pumping into the pulmonary circulation. A heart which cannot pump sufficient blood to meet the body's requirements (i.e., heart failure) will often, but not invariably, have a reduced ventricular ejection fraction.
Right ventricular hypertrophy (thickening of the muscular walls of the right ventricle, this is a result of the increased amount of work the heart has to do) Ventricular septal defect (a hole exists in the septum that divides the left and right ventricles)
A blood volume increase would cause a shift along the line to the right, which increases left ventricular end diastolic volume (x axis), and therefore also increases stroke volume (y axis). The Frank–Starling law of the heart (also known as Starling's law and the Frank–Starling mechanism ) represents the relationship between stroke volume ...
[1] [2] This means that all atrial cells can contract together, and then all ventricular cells. Different shapes of the cardiac action potential in various parts of the heart Rate dependence of the action potential is a fundamental property of cardiac cells and alterations can lead to severe cardiac diseases including cardiac arrhythmia and ...
