The ECG comes from a Holter monitor. She has arterial hypertension and coronary artery disease. The ECG shows a second-degree, Mobitz Type II AV block. In both types of AVB, the PP intervals are usually the same. In second-degree AVB, Type I, the PQ (or PR) intervals progressively prolong until a P wave fails to produce a QRS.&nbsp; The cycle repeats.&nbsp; In second-degree AVB, Type II, the PQ intervals stay the same.&nbsp; This is best identified by comparing the PQ intervals from just before the failed QRS and just after.&nbsp; In Type II AVB, those two PQ intervals must remain the same.</p> <p>&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/575/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 Second degree AVB Mobitz Type II 1/5</option><option value="40">Give Second degree AVB Mobitz Type II 2/5</option><option value="60">Give Second degree AVB Mobitz Type II 3/5</option><option value="80">Give Second degree AVB Mobitz Type II 4/5</option><option value="100">Give Second degree AVB Mobitz Type II 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" name="op" value="Rate" /><input type="hidden" name="form_build_id" value="form-5HSIGWscN5CQ1_NGzQeE6tMvr_iGs1UTexEcOQTRplQ" /> <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%2Fsecond-degree-avb-mobitz-type-ii&amp;title=Second%20degree%20AVB%20Mobitz%20Type%20II"><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> Sat, 27 May 2023 07:35:53 +0000 Dr A Röschl 842 at https://www.ecgguru.com https://www.ecgguru.com/blog/second-degree-avb-mobitz-type-ii#comments
