R intervals, making this a somewhat <strong>regularly-irregular</strong> &nbsp;rhythm, as opposed to the irregular irregularity of atrial fibrillation. &nbsp;The flutter waves (P waves) are very easy to see in most leads, but not in all. &nbsp;If you are teaching students who are making the transition from reading monitors and rhythm strips to 12-lead ECGs, this is a great ECG to illustrate for them how the more leads you have, the more you will see. &nbsp;The flutter waves are invisible in Lead I and, to the untrained eye, they may be hard to see in the precordial leads. &nbsp;The four channels on this ECG are run simultaneously, so if &nbsp;P waves or flutter waves are visible in one lead, they are also present in all leads that line up vertically with that one. &nbsp;In other words, the Lead II rhythm strip at the bottom confirms that flutter waves exist across the entire ECG.</p><p>The R - R intervals in this ECG reflect alternating 2:1 and 4:1 conduction. &nbsp;There are a couple of times when the 4:1 ratio repeats itself without alternating. &nbsp;Often, the length of these varying R - R intervals will be multiples of each other, or have a common denominator. &nbsp;These do not appear to, and may reflect the fact that, when R to P intervals lengthen, R to R intervals sometimes shorten. &nbsp;In other words, the PR intervals, which are difficult to measure in atrial flutter, may be changing. &nbsp;I would invite my colleagues with more expertise in this area to comment below.</p><p>There are no blatant ST segment abnormalities here, but ST segments can be very difficult to assess in atrial flutter because of the flutter waves. &nbsp;We do not have clinical data, other than this is a 62-year-old man.</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/600/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 Atrial Flutter With Variable Conduction 1/5</option><option value="40">Give Atrial Flutter With Variable Conduction 2/5</option><option value="60">Give Atrial Flutter With Variable Conduction 3/5</option><option value="80" selected="selected">Give Atrial Flutter With Variable Conduction 4/5</option><option value="100">Give Atrial Flutter With Variable Conduction 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >3.4</span></span> <span class="total-votes">(<span >52</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-EeR8KdyW_POwnigsimuNUHzItYKHpJcrhAkdezFevXY" /> <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/atrial-flutter-0" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Atrial flutter</a></div><div class="field-item odd"><a href="/ecg/tachycardia" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Tachycardia</a></div><div class="field-item even"><a href="/ecg/wenckebach-conduction" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Wenckebach Conduction</a></div><div class="field-item odd"><a href="/ecg/grouped-beating" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Grouped beating</a></div><div class="field-item even"><a href="/ecg/atrial-flutter-ariable-conduction" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Atrial flutter with ariable conduction</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%2Fatrial-flutter-variable-conduction-1&amp;title=Atrial%20Flutter%20With%20Variable%20Conduction"><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, 04 Nov 2014 06:24:57 +0000 Dawn 604 at https://www.ecgguru.com https://www.ecgguru.com/ecg/atrial-flutter-variable-conduction-1#comments
