Where is an inferior infarct?
Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
What is an inferior infarct on an ECG?
Inferior Wall ST Segment Elevation Myocardial Infarction (MI) ECG Review. An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
What part of the heart is affected in an inferior MI?
While inferior wall MIs traditionally have a good prognosis, there are a few factors that may increase mortality. Approximately 40% of inferior wall infarctions also involve the right ventricle. Right ventricular infarctions are very pre-load dependent, and nitrates may precipitate a drop in blood pressure.
Is an inferior infarct serious?
Inferior myocardial infarctions have multiple potential complications and can be fatal. See the review on ST elevation myocardial infarction for more detail on complications of an inferior myocardial infarction and a detailed discussion on treatment.
What is an inferior infarct of undetermined age?
If the finding on an ECG is “septal infarct, age undetermined,” it means that the patient possibly had a heart attack at an undetermined time in the past. A second test is typically taken to confirm the finding, because the results may instead be due to incorrect placement of electrodes on the chest during the exam.
How is inferior myocardial infarction treated?
FIELD TREATMENT Fluid infusion is the mainstay of treatment for patients with RVI. In the case of an inferior MI with right ventricular involvement, the administration of nitroglycerin and morphine could cause an abrupt drop in blood pressure.
What is inferior infarct age undetermined?
Which coronary artery is blocked in inferior MI?
Acute Inferior Wall Myocardial Infarction due to Occlusion of the Wrapped Left Anterior Descending Coronary Artery.
How is inferior infarct treated?
How common is inferior ischemia?
Approximately 40 percent of myocardial infarctions involve the inferior wall. Traditionally, inferior MIs have a better prognosis than those in other regions, such as the anterior wall of the heart.
Is Anteroseptal infarction serious?
Anteroseptal myocardial infarctions are commonly caused by the rupture of an unstable atherosclerotic plaque in the left anterior descending artery. Delayed or missed diagnosis of an anteroseptal myocardial infarction can lead to high morbidity and mortality.
