Myocardial contractility - Wikipedia
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.
What Is Cardiac Contractility and How Is It Regulated?
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 …
Cardiac contractility: Video, Causes, & Meaning | Osmosis
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 …
Regulation of Cardiac Contractility - NCBI Bookshelf
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).
Muscle Contractility - an overview | ScienceDirect Topics
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 …
Cardiac Inotropy (Contractility) - CV Physiology
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 Definition - Anatomy and Physiology II Key Term | Fiveable
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 …
Myocardial Contractility: Historical and Contemporary Considerations
Mar 31, 2020 · The term “contractility” is historically embedded in both the experimental and clinical cardiovascular literature and is formed from the adjective contractile and the suffix “ ility ” (i.e., …
The Clinical Significance of Contractility in Cardiology
Jun 19, 2025 · Cardiac contractility is a fundamental aspect of cardiovascular physiology, reflecting the intrinsic ability of the heart muscle to contract and pump blood efficiently. Understanding the clinical …
Contractility - wikidoc
Myocardial Contractility is a term used in physiology to describe the performance of cardiac muscle. It is often defined as: the intrinsic ability of a cardiac muscle fibre to contract at a given fibre length.
