He is twelve months after PCI (RCA, RCX). Currently no symptoms (no dyspnea, no chestpain, no palpitations). You can see that an overview/section from a Holter- EKG, 3 channels are shown, strip width is 30 seconds. First you can see a sinus rhythm with frequent PVCs, then there is a transition to an accelerated idioventricular rhythm (AIVR) that lasts almost a minute in total.&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/827/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 AIVR - Accelerated Idioventricular Rhythm 1/5</option><option value="40">Give AIVR - Accelerated Idioventricular Rhythm 2/5</option><option value="60" selected="selected">Give AIVR - Accelerated Idioventricular Rhythm 3/5</option><option value="80">Give AIVR - Accelerated Idioventricular Rhythm 4/5</option><option value="100">Give AIVR - Accelerated Idioventricular Rhythm 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >3</span></span> <span class="total-votes">(<span >1</span> vote)</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-8XsBjtQDZOKt59S60JBTR1TtAWSmpqWzYhgMDTjBEyM" /> <input type="hidden" name="form_id" value="fivestar_custom_widget" /> </div></form></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%2Fblog%2Faivr-accelerated-idioventricular-rhythm&amp;title=AIVR%20-%20Accelerated%20Idioventricular%20Rhythm"><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> Sun, 28 May 2023 08:21:59 +0000 Dr A Röschl 844 at https://www.ecgguru.com https://www.ecgguru.com/blog/aivr-accelerated-idioventricular-rhythm#comments ECG Basics: Accelerated Idioventricular Rhythm https://www.ecgguru.com/ecg/ecg-basics-accelerated-idioventricular-rhythm <div class="field field-name-field-ecg field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/ecg/ecg-basics-accelerated-idioventricular-rhythm"><img typeof="foaf:Image" src="https://www.ecgguru.com/sites/default/files/Rhythm%20Strip%2000-46-00.jpg" width="1341" height="540" alt="" /></a></div></div></div><div class="field field-name-field-ecg-interpretation field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>This rhythm strip is taken from a 67 year old man with chest pain who had ECG signs of inferior-posterior  wall M.I. upon the arrival of paramedics.  He had a recent (5 day) history of cardiac cath and stent placement.  During his treatment, his condition and ECG signs improved somewhat, and it was felt that he spontaneously reperfused during transport.  Often, during reperfusion of the heart after a total or near-total occlusion, dysrhythmias will appear.  They are usually transient.  This strip shows accelerated idioventricular rhythm.  The criteria are:  wide complex rhythm with no P waves associated, rate between 40 and 100 bpm.  The rate can go higher. Some people would prefer the term V Tach when the rate is over 100.  This rhythm, however, is not usually as sinister as V Tach.Sometimes, it can be difficult to differentiate AIVR from sinus rhythm with hidden P waves and a conduction defect such as bundle branch block, which widens the QRS.  Artifact such as we see here can obscure P waves, as can a very fast rate.  The real clue to this being AIVR is the "capture" beat - number 15 - at the end.  This is a sinus beat, proving that there is a separate underlying sinus rhythm.  Beat number 2 is a fusion beat - the ventricular beat coming from below has "collided" with the supraventricular depolarization wave from above (in this case a PAC).  The resulting QRS has characteristics of both beats.    This AIVR has taken over the heart, as the FASTEST PACEMAKER CONTROLS THE HEART.  To see a series of 12-lead ECGs from this patient, go to <a href="http://ecgguru.com/ecg/teaching-series-112213-inferior-posterior-wall-mi-right-ventricular-mi">http://ecgguru.com/ecg/teaching-series-112213-inferior-posterior-wall-mi...</a></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/827/feed" method="post" id="fivestar-custom-widget--2" 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--4" name="vote" class="form-select"><option value="-">Select rating</option><option value="20">Give ECG Basics: Accelerated Idioventricular Rhythm 1/5</option><option value="40">Give ECG Basics: Accelerated Idioventricular Rhythm 2/5</option><option value="60">Give ECG Basics: Accelerated Idioventricular Rhythm 3/5</option><option value="80" selected="selected">Give ECG Basics: Accelerated Idioventricular Rhythm 4/5</option><option value="100">Give ECG Basics: Accelerated Idioventricular Rhythm 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 >4</span> votes)</span></div></div> </div> </div> </div><input class="fivestar-submit form-submit" type="submit" id="edit-fivestar-submit--2" name="op" value="Rate" /><input type="hidden" name="form_build_id" value="form-7s3pbzykQPfzplvzjuTRRiYnE40RHqwG9onoCcbdIBg" /> <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/ecg-basics" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">ECG Basics</a></div><div class="field-item odd"><a href="/ecg/accelerated-idioventricular-rhythm" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Accelerated idioventricular rhythm</a></div><div class="field-item even"><a href="/ecg/aivr" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">AIVR</a></div><div class="field-item odd"><a href="/ecg/basic-ecg" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Basic ECG</a></div><div class="field-item even"><a href="/ecg/rhythm-strip" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Rhythm strip</a></div></div></div><ul class="links inline"><li class="addtoany first last"><span><span class="a2a_kit a2a_target addtoany_list" id="da2a_2"> <a class="a2a_dd addtoany_share_save" href="https://www.addtoany.com/share#url=https%3A%2F%2Fwww.ecgguru.com%2Fecg%2Fecg-basics-accelerated-idioventricular-rhythm&amp;title=ECG%20Basics%3A%20%20Accelerated%20Idioventricular%20Rhythm"><img src="/sites/all/modules/addtoany/images/share_save_256_24.png" width="256" height="24" alt="Share"/></a> </span> </span></li> </ul> Wed, 04 Dec 2013 04:07:26 +0000 Dawn 523 at https://www.ecgguru.com https://www.ecgguru.com/ecg/ecg-basics-accelerated-idioventricular-rhythm#comments
