In an ischemic heart, the affected cardiac muscle cells are likely to have an altered resting membrane potential.
Ischemia is the term used to describe cell and tissue damage brought on by inadequate blood and oxygen delivery.
Scar tissue, which lacks the original tissue's regular cell structure, typically replaces the injured tissue.
Therefore, the pumps and channels required to create resting membrane potential would be absent in "scarred" heart muscle.
Ischemia is described as a localized lack of blood flow (circulation) brought on by a blockage of the blood arteries feeding the region.
An organ (such as the heart) is said to be ischemic if it is not receiving enough blood and oxygen.
The term "ischemic heart disease," also known as "coronary heart disease" or "coronary artery disease," refers to cardiac conditions brought on by clogged coronary arteries, which feed blood to the heart muscle.
