Q wave myocardial infarction refers to myocardial infarctions that in a Q wave forming on the 12-lead ECG once the infarction is completed. It was once believed that the development of Q waves ...

non-Q wave MI, transmural MI and non-transmural MI are no longer recommended for use. Instead, acute coronary syndromes are classified as unstable angina, non-ST elevation myocardial infarction ...

The ECG findings of an old anterior myocardial infarction include: Loss of anterior forces leaving Q waves in leads V1 and V2. This is sometimes termed "poor R wave progression" or PRWP.

An anterior wall myocardial infarction occurs when anterior myocardial ... is concave downward and frequently overwhelms the T wave. This is called “tombstoning” for obvious reasons; the ...
