In this ECG, the patient produces P waves, but fails to transmit them to the ventricles due to AV block.&nbsp; The electronic pacemaker&nbsp;SENSES the native P waves, and TRIGGERS the ventricular wire to pace the ventricle in response.&nbsp; Using this pacemaker function, the heart rate can be controlled by the patient's own nervous system, as P waves are produced naturally.&nbsp; Should the patient fail to produce a P wave within rate guidelines set by the implanting physician, the pacer will pace the atrial as well.</p> <p>The QRS complex is wide when only the right ventricle is paced, as the impulse has to travel from the RV to the LV cell-by-cell.&nbsp; This slows conduction in the same way a ventricular rhythm like VTach is slowed, producing a wide QRS.&nbsp; Remember, a wide QRS causes lower cardiac output, as much as 15%.</p> <p>For your students who are learning axis, show them an illustration of the heart with the pacing wire in the right ventricle.&nbsp; It is easy to see why the axis is leftward when the left ventricle is being paced from the right ventricle.</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/135/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 Pacemaker Rhythm, Right Ventricular Pacing Triggered by Native P Waves 1/5</option><option value="40">Give Pacemaker Rhythm, Right Ventricular Pacing Triggered by Native P Waves 2/5</option><option value="60" selected="selected">Give Pacemaker Rhythm, Right Ventricular Pacing Triggered by Native P Waves 3/5</option><option value="80">Give Pacemaker Rhythm, Right Ventricular Pacing Triggered by Native P Waves 4/5</option><option value="100">Give Pacemaker Rhythm, Right Ventricular Pacing Triggered by Native P Waves 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >2.7</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-eVe6ZulqxgyKjRyPjSGx-jsdyrT_y7-uRslIVoLRzCY" /> <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/pacemaker" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Pacemaker</a></div><div class="field-item odd"><a href="/ecg/paced-rhythm" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Paced rhythm</a></div><div class="field-item even"><a href="/ecg/triggered-pacing" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Triggered pacing</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%2Fpacemaker-rhythm-right-ventricular-pacing-triggered-native-p-waves&amp;title=Pacemaker%20Rhythm%2C%20Right%20Ventricular%20Pacing%20Triggered%20by%20Native%20P%20Waves"><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();
