For years, aVR was virtually ignored in the literature, and considered to be only a reciprocal view of the lateral inferior wall. Now, there is convincing evidence of its usefulness in discovering proximal left coronary artery occlusion and severe triple vessel disease. ST elevation in aVR can be a reliable sign of ischemia of the basal part of the heart and the proximal IV septum.</p> <p>Many people with complete occlusion of the left main do not survive. When there is&nbsp;diminished blood flow through the blocked area in the proximal LAD or left main, this pattern may appear. Look for ST elevation in aVR greater than or equal to 1 mm, ST elevation in aVR greater than the ST elevation in V1, and widespread ST depression.</p> <p>For complete discussions on this topic, go to <a title="ST elevation in aVR" href="http://lifeinthefastlane.com/ecg-library/lmca/"><span style="color: #0062a0;">Life in the Fast Lane</span></a>,</p> <p><a title="ST elev in aVR with widespread ST dep" href="http://hqmeded-ecg.blogspot.com/2011/04/st-elevation-in-avr-with-widespread-st.html"><span style="color: #0062a0;"> Dr. Smith's ECG Blog</span></a>,</p> <p><a title="ST elevation in aVR" href="http://content.onlinejacc.org/cgi/content/full/38/5/1355"><span style="color: #0062a0;">JACC</span></a></p> </div> </div> </div> </div> <p>&nbsp;</p> <p>&nbsp;</p> </div> </div> </div> </div> </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/218/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 Left Main Coronary Artery Occlusion 1/5</option><option value="40">Give Left Main Coronary Artery Occlusion 2/5</option><option value="60">Give Left Main Coronary Artery Occlusion 3/5</option><option value="80" selected="selected">Give Left Main Coronary Artery Occlusion 4/5</option><option value="100">Give Left Main Coronary Artery Occlusion 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >4</span></span> <span class="total-votes">(<span >5</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-wuFwvTr10xefL_cgWtW4LV4vjmT5aSddyjCpKxk2j_U" /> <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/left-main-coronary-artery-occlusion-0" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Left main coronary artery occlusion</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/myocardial-infarction" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Myocardial infarction</a></div><div class="field-item odd"><a href="/ecg/st-elevation" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">ST elevation</a></div><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></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%2Fleft-main-coronary-artery-occlusion&amp;title=Left%20Main%20Coronary%20Artery%20Occlusion"><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> Thu, 25 Oct 2012 01:34:14 +0000 Dawn 355 at https://www.ecgguru.com https://www.ecgguru.com/ecg/left-main-coronary-artery-occlusion#comments
