Patients with ST elevation >0.05 mV or pathologic Q wave in the posterior leads, as well as those with specific changes indicating posterior MI in V1-V2, were evaluated by echocardiography in terms of wall motion abnormalities. All data were analyzed using SPSS and p<0.05 were considered ...
This picture illustrates the reciprocal relationship between the ECG changes seen in STEMI and those seen with posterior infarction. The previous image (depicting posterior infarction in V2) has been inverted. See how the ECG now resembles a typical STEMI! Posterior leads Leads V7-9 are placed on...
A 60 year old woman with 3 hours of chest pain. Acute posterior myocardial infarction (hyperacute) the mirror image of acute injury in leads V1 - 3 (fully evolved) tall R wave, tall upright T wave in leads V1 -3 usually associated with inferior and/or lateral wall MI...
The overall subtle changes in the ECG may be due to cancellation of electrical forces by an infarction in another area. This may present as a cardiogenic shock and may lead to other mechanical complications of acute myocardial infarction-like ventricular septal rupture, free wall rupture, etc. [...
posterior cranial fossa haemorrhageWithout significant coronary artery stenosis, ischemic ECG changes including ST segment elevation, segmental wall abnormality & elevated serum cardiac specific markers may develop after central nervous system injuries. Misdiagnosing these patients as acute MI may result in ...

The ablation strategy for persistent AF adds linear ablation of the mitral isthmus (MI) and electrical isolation of left atrial (LA) posterior wall (PW) using ablation index (AI)-guided high-power ablation (no fragmented potential ablation was performed at the index procedure) was not reported....
