"Sawtooth" flutter waves are readily visible in Leads II, III, avF, and V1, typically good "P wave" leads.&nbsp; Other leads show small, discreet P waves that the beginning student might not recognize as flutter waves because they don't produce the sawtooth pattern.&nbsp; The P waves' rate,&nbsp;approximately 360/min., gives them away as atrial flutter.&nbsp; This is also a good example of a constant 4:1 conduction, resulting in a regular QRS rhythm and regular pulse, at a rate of about 90/min.&nbsp; This demonstrates that not all narrow-complex rhythms between 60 and 100 bpm are "NSR".&nbsp;&nbsp;The low voltage in the limb leads makes this a good ECG to demonstrate that the flutter waves are regular and do not pause when the QRS happens, illustrating the separate actions of the atria and the ventricles.&nbsp; For students just learning 12-lead interpretation, this ECG serves to show that acute ST elevation M.I. is not the only valuable information that can be obtained from a 12-Lead, and that some leads are better than others for showing dysrhythmias.</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/21/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 1/5</option><option value="40">Give Atrial Flutter 2/5</option><option value="60">Give Atrial Flutter 3/5</option><option value="80">Give Atrial Flutter 4/5</option><option value="100" selected="selected">Give Atrial Flutter 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >4.7</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-Zn5NsCjkK42IYcQ4Ai8LyF75zzGv9Qyn06XPRnWQkM8" /> <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/pacemaker-mediated-tachycardia" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Pacemaker mediated tachycardia</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&amp;title=Atrial%20Flutter"><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, 19 Jan 2013 22:22:44 +0000 Dawn 393 at https://www.ecgguru.com https://www.ecgguru.com/ecg/atrial-flutter#comments Pacemaker Mediated Tachycardia https://www.ecgguru.com/ecg/pacemaker-mediated-tachycardia <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/pacemaker-mediated-tachycardia"><img typeof="foaf:Image" src="https://www.ecgguru.com/sites/default/files/PM105.jpg" width="1440" height="330" 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><span class="Object-hover"><strong>PACEMAKER MEDIATED TACHYCARDIA</strong> is a term for several different mechanisms that cause inappropriately fast rates in a paced patient.

If you or your teachers have not worked in an electrophysiology setting, you are almost sure to be lacking in the very latest information.&nbsp; I still find many of my students do not know that dual-chamber pacemakers can sense a patient's own (native) p wave, and track those p waves, triggering paced QRS complexes for each Q wave.&nbsp; This allows a patient with good sinus node function to be paced at the rate which best fits his or her needs.</span></p> <p><span class="Object-hover">Modern pacemakers can pace and sense the right atrium, the right ventricle, and often the left ventricle.&nbsp; Some devices can defibrillate and cardiovert tachycardias.
