Due to the impressive QRS voltage and overlapping waveforms, I initially debated on whether or not I should post this at 1/2-standard but in the end I decided to retain its original size.&nbsp; This ECG is from 27 years ago so I have very limited information, but this is what I do know. <br><br><span style="text-decoration: underline;"><strong>Patient's clinical data:</strong></span>&nbsp; 37-year-old white man who presented to the emergency room in this rhythm.&nbsp; Since he had no prior serial ECGs to compare this to, this ECG was serving as his "baseline".<br><br><span style="text-decoration: underline;"><strong>Questions:</strong></span>&nbsp; What is the source of this mechanism and what might you expect to see once the patient's "normal" rhythm was restored?&nbsp; Would you give verapamil for this rhythm?&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/163/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 Jason&amp;#039;s Blog: ECG Challenge of the Week for Dec. 16th - 23rd. 1/5</option><option value="40">Give Jason&amp;#039;s Blog: ECG Challenge of the Week for Dec. 16th - 23rd. 2/5</option><option value="60">Give Jason&amp;#039;s Blog: ECG Challenge of the Week for Dec. 16th - 23rd. 3/5</option><option value="80" selected="selected">Give Jason&amp;#039;s Blog: ECG Challenge of the Week for Dec. 16th - 23rd. 4/5</option><option value="100">Give Jason&amp;#039;s Blog: ECG Challenge of the Week for Dec. 16th - 23rd. 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >3.7</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-xJElmgl-n5EI8shvNwkmQEmnDNGPxf_oB26Ikhtzs0E" /> <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%2Fjasons-blog-ecg-challenge-week-dec-16th-23rd&amp;title=Jason%27s%20Blog%3A%20ECG%20Challenge%20of%20the%20Week%20for%20Dec.%2016th%20-%2023rd."><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();

This pathway is called the Bundle of Kent. This ECG clearly demonstrates the "delta wave" caused by the atrial impulse traveling around the AV node and pre-exciting part of the ventricle. These delta waves are best seen in Leads I and V4 - V6. The delta wave in Lead II is a small notch. A short PR interval is also seen. The accessory pathway can, along with the normal pathway through the AV node, form a circle or circuit, making the heart vulnerable to re-entrant tachycardia. This ECG is from a four-year-old girl who had not been previously diagnosed.</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/163/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 Wolff-Parkinson-White Syndrome in a Four-Year-Old Girl 1/5</option><option value="40">Give Wolff-Parkinson-White Syndrome in a Four-Year-Old Girl 2/5</option><option value="60">Give Wolff-Parkinson-White Syndrome in a Four-Year-Old Girl 3/5</option><option value="80">Give Wolff-Parkinson-White Syndrome in a Four-Year-Old Girl 4/5</option><option value="100">Give Wolff-Parkinson-White Syndrome in a Four-Year-Old Girl 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="empty">No votes yet</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-dpNcx_33ERuLMdVOkoVETm54T_V_RPSB9NlFbIKGpJc" /> <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/wolff-parkinson-white" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Wolff-Parkinson-White</a></div><div class="field-item odd"><a href="/ecg/pediatric-ecg" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Pediatric ECG</a></div><div class="field-item even"><a href="/ecg/accessory-pathway" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Accessory pathway</a></div><div class="field-item odd"><a href="/ecg/kent-bundle" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Kent Bundle</a></div><div class="field-item even"><a href="/ecg/delta-wave" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Delta wave</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%2Fwolff-parkinson-white-syndrome-four-year-old-girl&amp;title=Wolff-Parkinson-White%20Syndrome%20in%20a%20Four-Year-Old%20Girl"><img src="/sites/all/modules/addtoany/images/share_save_256_24.png" width="256" height="24" alt="Share"/></a> </span> </span></li> </ul> Mon, 19 Dec 2011 18:21:07 +0000 Dawn 140 at https://www.ecgguru.com https://www.ecgguru.com/ecg/wolff-parkinson-white-syndrome-four-year-old-girl#comments
