hemodynamics
Pronunciation: HEE-moh-dy-NAM-iks
The study of blood flow dynamics and pressure within the cardiovascular system.
Full Definition
The branch of physiology dealing with the physical principles governing blood circulation, including pressure gradients, flow rates, and resistance within blood vessels. In angiological practice, hemodynamic assessment is crucial for evaluating vessel function, determining the significance of stenoses, and planning interventional procedures. This includes measurement of pressure gradients across lesions and calculation of flow reserve.
Usage
Usage note: Singular in form but can take singular or plural verbs depending on context.
