What does possible inferior infarct mean on an EKG?

What does possible inferior infarct mean on an EKG?

An inferior myocardial infarction (MI) is a heart attack or cessation of blood flow to the heart muscle that involves the inferior side of the heart. Inferior MI results from the total occlusion of either the right coronary artery in 85\% of the cases or the left circumflex in 15\% of the cases.

Is 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 does Anteroseptal infarct age indeterminate mean?

Anteroseptal MI on ECG usually is characterized by the presence of ST-elevations in V1-V3 leads acutely followed by the development of Q waves in V1-V3 precordial leads. The presence of Q-waves in these leads is classically referred to as an age-indeterminate anteroseptal infarct.

Is an anterior infarct a heart attack?

Anterior myocardial infarction (AMI) is a common heart disease associated with significant mortality and morbidity.

How is inferior infarct treated?

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 the treatment for anterior infarct?

Once the patient reaches hospital, the major aim of treatment is to decrease the size of the infarct. Fibrinolytic therapy with streptokinase or tissue plasminogen activator (tPA) restores coronary patency and significantly reduces mortality. Aspirin is mandatory unless there are absolute contraindications to its use.

How do you treat inferior myocardial infarction?

While heart blocks are a main contributor to morbidity and mortality, most high-degree heart blocks are treatable with atropine. It is seldom necessary to use a temporary pacemaker. The damaged myocardium can lead to potentially lethal arrhythmias such as ventricular tachycardia and ventricular fibrillation.

What is an old infarct meaning?

Infarction is tissue death (necrosis) due to inadequate blood supply to the affected area. It may be caused by artery blockages, rupture, mechanical compression, or vasoconstriction. The resulting lesion is referred to as an infarct (from the Latin infarctus, “stuffed into”).

What are the signs of old myocardial infarction?

pressure or tightness in the chest. pain in the chest, back, jaw, and other areas of the upper body that lasts more than a few minutes or that goes away and comes back. shortness of breath. sweating.

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.

What is an infarct and what causes it?

Infarction is tissue death or necrosis due to inadequate blood supply to the affected area. It may be caused by artery blockage, rupture, mechanical compression, or vasoconstriction. Infarction care is divided based on histopathology (white infarction and red infarction) and location (heart, brain, lung, etc.).

What would be expected when evaluating an ECG for an anterior infarction?

ST elevation in I and aVL with reciprocal ST depression in lead III. Q waves are present in the septal leads V1-2. These features indicate a hyperacute anteroseptal STEMI.

What is probable inferior infarct?

An inferior myocardial infarction is a problem with the heart where cells along the inferior wall of the heart die in response to oxygen deprivation. This most commonly occurs as a result of a blockage in the right coronary artery, cutting off the supply of blood to this area of the heart.

How is an inferior infarction diagnosed?

Tell-tale signs of an inferior myocardial infarction can be detected in an electrogram. In an electrocardiogram, tell-tale signs of an inferior myocardial infarction can be seen, even after the acute attack is already over.

What is an old inferior infarction?

An EKG /ECG that finds dead tissue of undetermined age in the inferior heart wall is called an “inferior infarct, age undetermined.”. An infarct is heart tissue that dies from a heart attack, which electrocardiograms, or EKG/ECG, detect because the dead muscle no longer contracts, according to WebMD and the American Heart Association.

What does inferior wall myocardial infarction mean?

An inferior wall infarct is a myocardial infarction involving the bottom of the left ventricle, usually caused by a blockage within the right coronary artery.
