Is an inferior infarct a heart attack?
An inferior myocardial infarction results from occlusion of the right coronary artery (RCA). This can cause a ST elevation myocardial infarction or a non-ST segment elevation myocardial infarction.
What does an inferior infarct mean?
Excerpt. 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.
Is inferior STEMI a heart attack?
So STEMI is basically a heart attack with a particular EKG heart-tracing pattern.
What does inferior 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 is inferior infarct on 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 does inferior infarct mean on EKG?
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.
How do you identify a myocardial infarction on an ECG?
In a myocardial infarction transmural ischemia develops. In the first hours and days after the onset of a myocardial infarction, several changes can be observed on the ECG. First, large peaked T waves (or hyperacute T waves), then ST elevation, then negative T waves and finally pathologic Q waves develop.
What level of troponin indicates a heart attack?
Laboratories measure troponin in nanograms per milliliter of blood (ng/ml). The University of Washington’s Department of Laboratory Medicine provides the following ranges for troponin I levels: Normal range: below 0.04 ng/ml. Probable heart attack: above 0.40 ng/ml.
What causes inferior wall myocardial infarction ( MI )?
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 does ” possible inferior infarct, age undetermined ” mean?
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 causes ST segment elevation in inferior myocardial infarction?
In the patients with inferior MI, ST segment elevation in one or more of leads I, aVL, V 5, and V 6 was highly suggestive of occlusion of the left circumflex artery (see Figure 7-20 ). Bairey et al. 42 also reported that ST segment elevation in the lateral leads identified circumflex artery occlusion as the cause of inferior MI.
What causes infarction of the posterior inferior cerebellar artery?
Posterior inferior cerebellar artery (PICA) occlusion may cause infarction of any part of the vascular territory of the PICA, namely the posterior inferior cerebellum, inferior cerebellar vermis, and lateral medulla.
