Wellens' syndrome, or "Widow Maker", is referred to as a pre-infarction syndrome with non-classical ischemic electrocardiographic (ECG) changes and
Engelsk titel: Acute coronary syndrome- ECG-changes without ST-elevation Läs prognosis with increased risk of a new myocardial infarction and death. in the left descending coronary artery (LAD) was evaluated prospectively in 138
Lateral leads = V5-6 . The different infarct patterns are named according to the leads with maximal ST elevation: Septal = V1-2. Anterior = V2-5. Anteroseptal = V1-4. Anterolateral = V3-6, I + aVL.
Anterolateral myocardial infarctions frequently are caused by occlusion of the proximal left anterior descending coronary artery, or combined occlusions of the LAD together with the right coronary artery or left circumflex artery. •Record leads V7-V9 •Correlates with posterior wall MI •Left circumflex infarct related artery in all J Am Coll Cardiol 1999;34:748. V7: posterior axillary line V8: posterior scapula line V9: Left border of spine V5-V9: same horizontal plane as V4 In general, the LAD artery and its branches supply most of the interventricular septum; the anterior, lateral, and apical wall of the left ventricle, most of the right and left bundle branches, and the anterior papillary muscle of the bicuspid valve (left ventricle). Therefore, patients with ST segment elevation in any 2 contiguous leads V 1-4, either alone or with associated changes in leads V5-6 and/or I and aVL, had LAD obstruction in 98.3%. In patients with ST segment elevation only in leads II, aVF and III, there was RCA obstruction in 85.7%.

Proximal occlusion in LAD – Proximal occlusion in LAD causes massive infarction involving the basal parts, anterosuperior wall, lateral wall and the interventricular septum. The more proximal the occlusion, the more leads display ST-segment elevation.
Knowing the definition, it’s easy to understand how an anteroseptal infarct can lead 2008-12-19 · When there is ST-segment elevation in leads V1-V4 we often simply say “LAD occlusion.” The lateral leads (I, aVL, V5 and V6) view the lateral wall of the left ventricle. Leads I and aVL are often referred to as the high lateral leads, because their positive electrode is on the left shoulder. Several ECG criteria have been reported to indicate a LAD artery occlusion proximal to the first septal perforator branch: (1) ST elevation in lead aVR (2) right bundle branch block (3) ST depression in lead V5 and (4) ST elevation in lead V1 >2.5mm Birnbaum et al found no association between ST elevation in lead V1 and LAD artery occlusion proximal to the first septal branch in one series Se hela listan på hindawi.com 2017-07-27 · Why it's important to identify right ventricular infarct A right-sided 12-lead EKG can identify signs of a right ventricular infarct to guide patient care decisions Article updated July 27, 2017 To the Editor: Recognition of characteristic changes in an electrocardiogram (ECG) that are associated with acute occlusion of a coronary artery guides decisions regarding immediate reperfusion the In this presentation, I discuss the origins of Fatty Streaks, Foam Cells, Clot Formation, the different types of Angina, Myociardia Injury, Ischemia, Infarct Therefore, patients with ST segment elevation in any 2 contiguous leads V 1-4, either alone or with associated changes in leads V5-6 and/or I and aVL, had LAD obstruction in 98.3%. In patients with ST segment elevation only in leads II, aVF and III, there was RCA obstruction in 85.7%. With a full-thickness infarct there may be ST depression over the reciprocal leads (inferior leads in an anterior infarct and anterior leads in an inferior infarct). T waves are higher and wider.
