What does possible lateral infarct age undetermined mean?
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.
What causes lateral infarct?
Isolated lateral wall myocardial infarction (LMI), similar to other acute myocardial infarctions (MI), is caused by acute atherosclerotic plaque rupture with subsequent thrombus formation in the left circumflex (LCx) coronary artery or one of its branches.
What happens in an infarct?
Acute Myocardial Infarction (heart attack) Acute myocardial infarction, also known as a heart attack, is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.
Is an infarct a heart attack?
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle….

What does lateral infarct mean on ECG?
A lateral 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 the left circumflex artery. Lateral MI is characterized by ST elevation on the electrocardiogram (EKG) in leads I and aVL.
Should I worry about abnormal ECG?
An abnormal ECG can mean many things. Sometimes an ECG abnormality is a normal variation of a heart’s rhythm, which does not affect your health. Other times, an abnormal ECG can signal a medical emergency, such as a myocardial infarction /heart attack or a dangerous arrhythmia.
What is lateral infarct on ECG?
How long can you live with myocardial infarction?
About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.
What causes infarction?
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”).
Is an infarction a stroke?
Infarction or Ischaemic stroke are both names for a stroke caused by a blockage in a blood vessel in the brain. This is the most common type of stroke.
What would be expected when evaluating an ECG for a lateral infarction?
High Lateral STEMI: ST elevation is present in the high lateral leads (I and aVL). There is reciprocal ST depression in the inferior leads (III and aVF). QS waves in the anteroseptal leads (V1-4) with poor R wave progression indicate prior anteroseptal infarction.
What causes lateral infarction?
Lateral extension of an anterior, inferior or posterior MI indicates a larger territory of myocardium at risk with consequent worse prognosis. Cause: The principal cause of infarction is atherosclerotic proximal occlusion of a coronary artery.
What is an old anterior infarction?
An anterior infarct is an infarct affecting the anterior surface of the heart – meaning the portion facing forward just beneath the chest wall. Usually, the left anterior descending artery is involved. Old, means just what it says – it is not new or acute.
What is inferior lateral myocardial infarction?
An inferior wall myocardial infarction – 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 is inferior wall infarct?
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.
