Activation in Cardiac Muscle
W hen a muscle is stimulated electrically, its ability to contract rises and then falls. It is conceptually easy to imagine, therefore, that something called the "active state" might rise and fall with a well-defined time course. Although the concept is simple, the attempts to measure this time course have produced such conflicting results that the whole concept has fallen into disrepute.1 Thes...
متن کاملActive contraction of cardiac muscle: in vivo characterization of mechanical activation sequences in the beating heart.
Progressive alterations in cardiac wall strains are a classic hallmark of chronic heart failure. Accordingly, the objectives of this study are to establish a baseline characterization of cardiac strains throughout the cardiac cycle, to quantify temporal, regional, and transmural variations of active fiber contraction, and to identify pathways of mechanical activation in the healthy beating hear...
متن کاملInitial mechanical efficiency of isolated cardiac muscle.
The aim of this study was to determine whether the initial mechanical efficiency (ratio of work output to initial metabolic cost) of isolated cardiac muscle is over 60%, as has been reported previously, or whether it is approximately 30%, as suggested by an estimate based on the well-established net mechanical efficiency (ratio of work output to total, suprabasal energy cost) of 15%. Determinat...
متن کاملMechanical and Electrical Oscillations in Cardiac Muscle of the Turtle
During contractures of the turtle ventricle rapid changes in length induce sinusoidal oscillations under isotonic conditions. They are due to delayed responses to stretching and release, which can be demonstrated also under isometric conditions. Oscillations of two distinct frequencies are produced under different conditions and are distinguished as high- and low-frequency oscillations. In depo...
