Inferior infarc

I also recently had an ECG come back abnormal stating that I had an Inferior Infarc of undetermined age.  What are these normal things that you speak of that can be mistaken for MI.  I too have a strong family history of heart disease and am continously checking on this issue.  Thank you.




This discussion is related to inferior infarct showing on my EKG.

Hi vincint, what did yuor Dr, say ddi he sugest any other test,like a stress or echo carda gram/  are yuo on medication. What was your reason for haveing the EKG?

I am assuming an abnormal Q waves as a vast majority are due to myocardial infarction, but a significant number are due to other causes. I don't believe you mean "normal things" but other conditions and situations that would produce an abnormal EKG tracing that is not due to an MI.

Noninfarction Q waves may be transient or permanent. It has been explained by a transient loss of electrophysiological function. Q waves have been recorded with severe metabolic disturbances accompanying shock or pancreatitis, transient ischemia and hypoxia, coronary spasm, localized metabolic and electrolyte disturbances, and possible hypothermia. Rarely a transient Q wave may result from tachycardia.

The largest group of noninfarction Q waves is due to myocardial disease, including myocarditis, postpartum myopathy, myocardial replacement by tumor,  idiopathic cardiomyopathy, anomalous coronary artery, and coronary embolism.

Noninfarction Q waves are common in hypertrophic cardiomyopathy and may simulate anterior or inferior myocardial infarction. Although the exact mechanism of the abnormal Q waves in this condition is unclear, increased septal mass or abnormal depolarization because of anomalous architecture of the septal myocardium, or both, have been proposed as the cause.  There are other causes that relate to respiratory disorder.

Other clinical evidence, symptoms and tests are required to make a differential diagnosis or rule not problematic.
