What are EKG changes associated with an inferior STEMI?
An STEMI, or ST-segment Elevation Myocardial Infarction, is a condition in which the blood flow to the heart is blocked. This typically occurs due to rupture of a lipid plaque in the wall of an epicardial artery. This causes muscle cell death due to lack of oxygen and other substrates necessary for cell growth/maintenance. The EKG can be used to localize the likely location of the blockage by looking at changes on the EKG. An inferior STEMI is characterized by ST elevations in the inferior limb leads, leads II, III, and aVF, associated with ST depressions (called reciprocal changes) in the lateral limb leads, I and aVL. An inferior STEMI most commonly is associated with a blockage in the right coronary artery (80% of the time). Inferior STEMIs have a slightly better prognosis than anterior MIs. There is typically less heart muscle lost in association with inferior STEMI than when the MI affects the bulkier left side of the heart.
What are kinds of stem?
Stems let food and water pass fromleaves to other parts of the plant. Stemsare very important to any plant that liveson earth. The flower has a small stem andthe tree has a big stem also known as atrunk. A stem is the main shaft of a plantthat develops buds and shoots andusually grows above ground. Stems arethe one thing that holds up the plant. Alsostems can be very stiff, as in tree stems,or trunks. Or a stem could be flexible, likea flower stem.More Stem FactsUnlike most animals, a plant growsthroughout its life. Growth not onlymakes the plant bigger, but alsoallows them to move. Plants cannotshift from one place to another, butplants can react to the world aroundthem. A plant's stem grows upwardtoward the light, and its roots growdownward into the ground. Someplants grow around others or catchhold of them, using slender leavescalled tendrils. These special kinds ofmovement in response to outsideconditions are called tropisms. Theyare caused by cells that grow atdifferent rates or when some cellsrapidly swell up or collapse. Forexample, if a plant grows in the open,all the tips of its stems receive thesame amount of light and grow at thesame speed. But if one side of a stemis shaded, the the stem has to bendtoward the light. This bendingmovement is called phototrtropism.Stems help them grow and live.Stems also help the plant supportitself.
