A measurable relative increase in contractility is a property of the myocardium similar to the term "inotropy". Contractility may be iatrogenically altered by the administration of inotropic agents.

Cardiac Inotropy (Contractility) Changes in inotropy are an important feature of cardiac muscle because, unlike skeletal muscle, cardiac muscle cannot modulate its force generation through changes in …

Contractility describes the relative ability of the heart to eject a stroke volume (SV) at a given prevailing afterload (arterial pressure) and preload (end-diastolic volume; EDV).

Contractility refers to the force of contraction of the heart muscle, which contributes to SV, and the ESV. The more forceful the contraction is, the greater the SV and the smaller the ESV are. In contrast, less …

Dec 13, 2025 · Cardiac contractility, often called inotropism, is the inherent strength of the heart muscle (myocardium) to contract and generate mechanical force. It measures the vigor of the heart’s …

Contractility is the ability of the heart muscle to contract and thereby pump blood. Cardiac contractility is determined by the interaction between intracellular calcium concentration, and the myofilament cross …

Nov 3, 2020 · Contractility = the change in force generated independent of preload. Inotropy and contractility are essential synonymous — inotropes are agents that increase contractility.

The meaning of CONTRACTILITY is the capability or quality of shrinking or contracting; especially : the power of muscle fibers of shortening into a more compact form.

Contractility is vital for heart function as it determines how forcefully the heart can pump blood with each beat. A strong contraction helps ensure adequate blood flow to meet the body's demands, especially …

Inotropic drugs are drugs that increase the force of contraction (they have positive contractility effects). Some examples of positive inotropic drugs include digoxin, sympathomimetic agents (like …
