Ischemic dilation refers to the enlargement of a heart chamber, typically the left ventricle, due to chronic ischemia, which is a reduced blood flow to the heart muscle. This condition often results from coronary artery disease, where the heart muscle becomes weakened and cannot contract effectively. As a result, the chamber may dilate to accommodate the increased volume of blood, leading to decreased cardiac efficiency and potential heart failure. This dilation is often a sign of underlying heart dysfunction.

Does an enlargement of a photograph represent a dilation or a rotation?

Dilation


What is the word for imperfect dilation?

The term for imperfect dilation is "hypodilation." It refers to a condition where dilation does not occur fully or adequately, which can affect various physiological functions, such as the dilation of blood vessels or pupils.


What does the word dilation in geometry mean?

Getting bigger. Dilation factor of 2, then it would get twice the size.


What are the invariant points of a dilation?

Invariant points of a dilation are the points that remain unchanged under the transformation. In a dilation centered at a point ( C ) with a scale factor ( k ), the invariant point is typically the center ( C ) itself. This means that when a point is dilated with respect to ( C ), it either moves closer to or further away from ( C ), but ( C ) does not move. Therefore, the only invariant point in a dilation is the center of dilation.


How can you determine whether a dilation's is a reduction or a enlargement?

To determine whether a dilation is a reduction or an enlargement, compare the scale factor to 1. If the scale factor is greater than 1, the dilation is an enlargement, as the image will be larger than the original. Conversely, if the scale factor is between 0 and 1, the dilation is a reduction, resulting in a smaller image. Additionally, you can observe the distances from the center of dilation; if they increase, it's an enlargement, and if they decrease, it's a reduction.
