Jun 20, 2015 · The changes are either deeply inverted T waves or biphasic T waves in these anterior leads, occurring in the pain-free interval after chest pain typical for ischemia. These patients often have an essentially normal EKG on presentation, with no ST-segment elevation or …

-Ischemia- when the hearts demand for oxygen exceeds its supply from the coronary circulation, represented by changes in T wave an ST segment depression (More than 1 mm below baseline), and reciprocal changes are seen in opposite leads-Injury- when the period of ischemia is prolonged more than just a few minutes, represented by ST elevation ...

Note- one normal ECG does not exclude cardiac ischemia. Leads & relationship to heart Septum = V1-V2 Anterior wall = V3-V4 Lateral wall = V5, V6, I, aVL Inferior wall = II, III, aVF. 1. Look for . Q waves. Pathological Q waves indicates an AMI (new or old). Any Q wave in V1-V3 0.03 seconds or wider (0.03 seconds is ¾ width of one little square)

Sep 02, 2015 · - 31% of anterior MIs also manifest upwardly concave ST segments in V3 - if T wave towers over R wave in V2 or V3 early repolarization unlikely. early repolarization. Ventricular aneurysm. EKG criteria - ST elevation most common in leads V2 and V3 - usually ≤ 3 mm and almost always ≤ 4 mm - T waves flattened or inverted, not tall or peaked

https://info.5y1.org/anterior-ischemia-ekg-leads_1_379b06.html
The 12 lead EKG primarily looks at the anterior heart, septal & anterior left ventricle (LV). The anterior LV (LAD): V2 (septal overlap) V3, V4. Wrapping around the heart (in latin: “circumflex”) is lateral LV territory, V5, V6, (with leads I & AVL.) Infarcting the LAD territory produces an anterior MI. V5 and V6 are on the left side of the ...
