An inferior wall mycardial infarction is a heart attack involving the inferior portion of the left ventricle, and in many cases the right ventricle. This is caused by occlusion of the right coronary artery. This can also indicate ischemia (poor oxygenation) of the AV node and bundle of HIS, as these structures are also supplied by the right coronary. An inferior wall MI can be seen in the inferior leads II, III, and AVF.

An inferior, not interior, infarction is a subclassification of a heart attack. An inferior myocardial infarction occurs when there is a blockage in the inferior wall of a coronary artery.
Ischemia is the condition in which an artery has become abnormally widened because of a weakness in the arterial wall.
Scintigraphy imaging showing Adenosine-induced ischemia in the lateral wall indicates reduced blood flow to that area of the heart during stress. This could suggest potential blockages or narrowing of the coronary arteries supplying blood to the lateral wall, which may require further evaluation and treatment to prevent cardiac complications.

Diaphragmatic attenuation typically refers to a decrease in image quality in the inferior wall of the heart due to interference from the diaphragm. Reversibility in the inferior wall usually indicates that a defect revealed during imaging is potentially reversible, often highlighting areas of reduced blood flow that may improve with treatment.
