Symptoms. Treatment. Outlook. If the finding on an ECG is “septal infarct, age undetermined,” it means that the patient possibly had a heart attack at an undetermined time in the past. Septal...
Jun 8, 2023 · This patient’s ECG shows several signs of a very proximal LAD occlusion (ostial LAD occlusion septal STEMI): There is a septal STEMI with ST elevation maximal in V1-2 (extending out to V3). There is a new bifascicular block (RBBB + LAFB)
The two main types of ischemia are transmural and subendocardial ischemia. Transmural ischemia implies that the entire wall thickness – from endocardium to epicardium – is affected in the area supplied by the occluded coronary artery. In subendocardial ischemia, only the subendocardium is affected.
Sep 2, 2016 · 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 display ST-segment elevations do reflect the ischemic area.
Mar 16, 2022 · Home ECG Library. This page covers the ECG signs of myocardial ischaemia seen with non-ST-elevation acute coronary syndromes (NSTEACS). ST-elevation and Q-wave myocardial infarction patterns are covered elsewhere: LMCA occlusion, Anterior STEMI, Lateral STEMI, Inferior STEMI, Right Ventricular Infarction, Posterior Infarction and Wellens syndrome.
Sep 28, 2023 · Septal infarction is when blood supply to the septum of the heart, the muscular wall that divides the left and right sides of the heart, becomes blocked, typically due to myocardial infarction.
For this purpose, the left ventricle is subdivided into 4 walls: inferior, anterior, lateral and septal wall (Figure 2 below). An inferior myocardial infarction refers to an infarction located in the inferior wall of the left ventricle.
