There is some coving upward of the ST segment in aVR, which can suggest a very proximal lesion of the left coronary artery (LCA). &nbsp;She was taken to the cath lab, where it was discovered that she had a 100% occlusion of the midportion of the anterior descending branch of the left coronary artery, which was repaired and stented. &nbsp;The <strong>second ECG,&nbsp;</strong>taken after the angioplasty, shows some Q waves in V1 and V2, with poor R wave progression in the V leads. &nbsp; A 25% occlusion of the obtuse marginal branch of the circumflex artery was stented two days later. The<strong> third ECG</strong> was obtained after that procedure. &nbsp;It shows that the Q waves have disappeared in the anterior leads (possibly due to different technicians performing the ECGs with different lead placement). &nbsp;It also shows marked T wave inversion in I and aVL, representing ischemia in the lateral wall, and in all the chest leads, representing ischemia in the anterior wall. &nbsp;The QTc is prolonged in this third ECG at 479 ms. &nbsp;It is not known what medications the patient was on. &nbsp;This patient also had a 50% proximal occlusion in the RCA and a 75% occlusion in the posterior descending artery. &nbsp; This is a good example of a patient with extensive coronary artery disease who finally presented for treatment when she developed ST elevation M.I. &nbsp;</p></div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div class="field-label">Rate this content:&nbsp;</div><div class="field-items"><div class="field-item even"><form class="fivestar-widget" action="/taxonomy/term/227/feed" method="post" id="fivestar-custom-widget" accept-charset="UTF-8"><div><div class="clearfix fivestar-average-text fivestar-average-stars fivestar-form-item fivestar-hearts"><div class="form-item form-type-fivestar form-item-vote"> <div class="form-item form-type-select form-item-vote"> <select id="edit-vote--2" name="vote" class="form-select"><option value="-">Select rating</option><option value="20">Give Anterior Wall M.I. 1/5</option><option value="40">Give Anterior Wall M.I. 2/5</option><option value="60">Give Anterior Wall M.I. 3/5</option><option value="80" selected="selected">Give Anterior Wall M.I. 4/5</option><option value="100">Give Anterior Wall M.I. 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >3.3</span></span> <span class="total-votes">(<span >3</span> votes)</span></div></div> </div> </div> </div><input class="fivestar-submit form-submit" type="submit" id="edit-fivestar-submit" name="op" value="Rate" /><input type="hidden" name="form_build_id" value="form-sv6CiSH4j8wJFXhj8YsqGS92scQBUqgaoe39gg1Z-T0" /> <input type="hidden" name="form_id" value="fivestar_custom_widget" /> </div></form></div></div></div><div class="field field-name-field-taxonomy field-type-taxonomy-term-reference field-label-above"><div class="field-label">Related Terms:&nbsp;</div><div class="field-items"><div class="field-item even"><a href="/ecg/anterior-wall-mi-5" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Anterior wall M.I.</a></div><div class="field-item odd"><a href="/ecg/stemi" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">STEMI</a></div><div class="field-item even"><a href="/ecg/cad" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">CAD</a></div><div class="field-item odd"><a href="/ecg/coronary-artery-disease-0" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Coronary artery disease</a></div></div></div><ul class="links inline"><li class="addtoany first last"><span><span class="a2a_kit a2a_target addtoany_list" id="da2a_1"> <a class="a2a_dd addtoany_share_save" href="https://www.addtoany.com/share#url=https%3A%2F%2Fwww.ecgguru.com%2Fecg%2Fanterior-wall-mi-1&amp;title=Anterior%20Wall%20M.I."><img src="/sites/all/modules/addtoany/images/share_save_256_24.png" width="256" height="24" alt="Share"/></a> </span> <script type="text/javascript"> <!--//--><![CDATA[//><!-- if(window.da2a)da2a.script_load(); //--><!]]> </script></span></li> </ul> Tue, 27 Aug 2013 21:03:26 +0000 Dawn 488 at https://www.ecgguru.com https://www.ecgguru.com/ecg/anterior-wall-mi-1#comments
