   Localization of myocardial infarction / ischemia using the ECG: the implications of ST segment elevation. It is possible to localize the ischemic area by using the ECG if there are ST-segment elevations. The reason why ST-segments are indicative of the ischemic area has been discussed (read ST-T changes in ischemia). Briefly, the ECG leads that ...

   If pathological Q-waves occur as a result of myocardial infarction, the infarction may be classified as Q-wave infarction (this has negligible clinical implication).Hence, Q-wave infarctions are mostly the result of transmural infarction (STEMI) but may be caused by extensive subendocardial ischemia ().

   What are the ECG criteria for myocardial infarction?

   • Current guidelines include ECG criteria for ST deviation, T-wave inversion, Q-waves, and R-waves. Hyperacute T-waves and fragmented QRS complexes are not included as criteria for myocardial infarction. The reason for this will be discussed later.

   Does v1 & v2 show ST-segment elevations during right ventricular infarction?

   • However, V1 and V2 may occasionally display ST-segment elevations during right ventricular infarction (the elevations should be higher in V1). To verify right ventricular infarction one must connect the right sided chest leads (V3R, V4R, V5R and V6R, which show ST-segment elevations).

   Which ECG findings are characteristic of acute myocardial infarction (MI)?

   • Abnormalities are manifest in the ST segment, T wave, and QRS complex. However, the ECG may be normal or nonspecific in these patients. In addition, findings thought typical of acute myocardial infarction (MI) due to atherosclerosis may occur in other conditions, such as myocarditis or stress cardiomyopathy.

   Sep 3, 2018 · Our understanding of the causes, diagnosis, and treatment of acute myocardial infarction (AMI) has evolved significantly over the last 40 years. In the early 20th century, AMI was generally considered a fatal event diagnosed only at autopsy. Until the 1970s, with appropriate understanding of its usual clinical presentation and diagnosis, it was ...
