Определение afterload в Английский Язык Английский Язык словарь
- The load on a working muscle from a constant opposing force
- (Tıp, İlaç) In cardiac physiology, afterload is used to mean the tension produced by a chamber of the heart in order to contract. If the chamber is not mentioned, it is usually assumed to be the left ventricle. However, the strict definition of the term relates to the properties of a single cardiac myocyte. It is therefore only of direct relevance in the laboratory; in the clinic, the term end-systolic pressure is usually more appropriate, although not equivalent
- {i} (In Cardiac Physiology) tension caused by the heart muscle after contraction
- The amount of tension a muscle must build up before it can start to contract For the heart, this is dependent on the aortic pressure Before the ventricle can start to move blood through the aortic valve the pressure in the ventricle must equal that in the aorta Press the "back" button to return to where you came from
- A load acted against by a contracting muscle
- the pressure or resistance against which the ventricles must pump to eject blood
