Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse. In effort to compensate the heart will increase cardiac output and heart rate, which accounts for the increased pulse pressure and sinus tachycardia. The condition … Web21 mrt. 2014 · There does appear to be some hyperdynamic flow through the third ventricle. (Large arrow) The aqueduct and the fourth ventricle also have flow within the structures. (Small arrow) This finding is seen with normal pressure hydrocephalus. Clinical correlation is suggested.

WebMedical Definition of hyperdynamic : marked by abnormally increased muscular activity especially when of organic origin myocardial infarction, with the remaining left ventricular walls being normal to hyperdynamic R. A. Is hyperdynamic a consequence? The hyperdynamic syndrome is a late consequence of portal hypertension in cirrhosis. A functional murmur (innocent murmur, physiologic murmur) is a heart murmur that is primarily due to physiologic conditions outside the heart, as opposed to structural defects in the heart itself. Serious conditions can arise even in the absence of a primary heart defect, and it is possible for peripheral conditions to generate abnormalities in the heart. Therefore, caution should be applied to use of the terms "innocent" or "benign" in this context.
