A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle.

12 lut 2023 · 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.
12-lead electrocardiogram showing ST-segment elevation (orange) in I, aVL and V1-V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction. The primary purpose of the electrocardiogram is to detect ischemia or acute coronary injury in broad, symptomatic emergency department populations.
Electrocardiography in suspected myocardial infarction has the main purpose of detecting ischemia or acute coronary injury in emergency department populations coming for symptoms of myocardial infarction (MI). Also, it can distinguish clinically different types of myocardial infarction.
14 paź 2007 · This is part of: Myocardial Infarction. ST elevation in II, III and aVF. ST elevation or depression in V4R can help in differentiating a RCA from a RCX occlusion. This part of the heart muscle lies on the diaphragm and is supplied of blood bij the right coronary artery (RCA) in 80% of patients.
28 paź 2012 · An inferior wall infarction is often accompanied with a decrease in heartrate because of involvement of the sinusnode. Longterm effects of an inferior wall infarction are usually less severe than those of an anterior wall infarction.
6 gru 2021 · The 12-lead ECG on admission shows atrial fibrillation. There is ST-segment elevation in leads II, III, aVF, and I, with ST-segment depression in leads aVL and V 1 through V 6, suggesting acute inferoposterior wall myocardial infarction.
