Cardiac Muscle Contraction For the heart to pump throughout the body,cardiac musclein the myocardium has to be excited and contract uniformly. This is facilitated by a cardiacaction potentialthat is due to a change in the voltage or membrane potential in the plasma membrane of cardiac myocytes....
The sarcolemma (plasma membrane) of an unstimulated muscle cell is polarized—that is, the inside of the sarcolemma is negatively charged with respect to t

摘要: Three numerical procedures are developed to approximate the solution of a nonlinear integro-differential system arising in a model of cardiac muscle contraction. Error estimates are derived for each method.关键词: Theoretical or Mathematical/ cardiology numerical methods physiological models/ error ...
Heart The heart acts as a pump and maintains circulation of the blood by alternate concentration and relaxation of cardiac muscle (the myocardium). It generally contracts at
