The QRS complexes are slightly wide at .10 seconds (100 ms), and they are within the parameters for supraventricular rhythm. The term, "junctional tachycardia" could be used, also, but this is not likely a "reentrant" junctional tachycardia, which would be fast, regular, and have a sudden onset. That type of junctional tachycardia is a PSVT. &nbsp; In this strip, we can see the underlying sinus rhythm in P waves that appear to pop up randomly. &nbsp;However, if you march out the P waves, you will find that they are regular, at a rate of about 90 per minute. &nbsp;The junctional rhythm has overrun the sinus rhythm. &nbsp;Most of the P waves cannot conduct due to where they have landed - in the refractory period of the QRS. &nbsp;The exception might be the P wave after the fifth QRS. &nbsp;The sixth QRS might be conducted from that P wave.</p><p>When accelerated junctional rhythm is encountered, you should suspect DIGITALIS TOXICITY - the classic dysrhythmia associated with digitalis toxicity is accelerated junctional rhythm. Other causes in adults could be beta-agonist drugs such as adrenalin, cardiac infection, ischemia, or surgery.<br />&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/61/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 ECG Basics: Accelerated Junctional Rhythm Overriding Normal Sinus Rhythm 1/5</option><option value="40">Give ECG Basics: Accelerated Junctional Rhythm Overriding Normal Sinus Rhythm 2/5</option><option value="60">Give ECG Basics: Accelerated Junctional Rhythm Overriding Normal Sinus Rhythm 3/5</option><option value="80" selected="selected">Give ECG Basics: Accelerated Junctional Rhythm Overriding Normal Sinus Rhythm 4/5</option><option value="100">Give ECG Basics: Accelerated Junctional Rhythm Overriding Normal Sinus 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 >6</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-gxFlDUlAloLhZ9WxEaOQpIbRserM-Gp_ZR91d3VAW44" /> <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/rhythm-strip" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Rhythm strip</a></div><div class="field-item even"><a href="/ecg/junctional-tachycardia" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Junctional tachycardia</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/normal-sinus-rhythm" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Normal sinus rhythm</a></div><div class="field-item odd"><a href="/ecg/accelerated-junctional-rhythm" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Accelerated junctional rhythm</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%2Fecg-basics-accelerated-junctional-rhythm-overriding-normal-sinus-rhythm&amp;title=ECG%20Basics%3A%20%20Accelerated%20Junctional%20Rhythm%20Overriding%20Normal%20Sinus%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> Wed, 17 May 2017 21:01:13 +0000 Dawn 730 at https://www.ecgguru.com https://www.ecgguru.com/ecg/ecg-basics-accelerated-junctional-rhythm-overriding-normal-sinus-rhythm#comments
