In some patients, preexisting cardiac conditions such as valve insufficiency or CHF may make this rate dangerous for the patient. &nbsp;The rate may lower cardiac output in some people, and this must be considered in light of the fact that the loss of P waves in atrial fib also lowers cardiac output significantly.</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/586/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: Atrial Fibrillation With a Rapid Ventricular Response 1/5</option><option value="40">Give ECG Basics: Atrial Fibrillation With a Rapid Ventricular Response 2/5</option><option value="60">Give ECG Basics: Atrial Fibrillation With a Rapid Ventricular Response 3/5</option><option value="80" selected="selected">Give ECG Basics: Atrial Fibrillation With a Rapid Ventricular Response 4/5</option><option value="100">Give ECG Basics: Atrial Fibrillation With a Rapid Ventricular Response 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 >4</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-LbsgIWfVOsR84EVF_7_bMBLsUGH7zFkbL6aDyj8kTwU" /> <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/basic-ecg" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Basic ECG</a></div><div class="field-item even"><a href="/ecg/atrial-fibrillation" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Atrial fibrillation</a></div><div class="field-item odd"><a href="/ecg/atrial-fibrillation-rapid-ventricular-response-0" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Atrial fibrillation with a rapid ventricular response</a></div><div class="field-item even"><a href="/ecg/fib" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">A Fib</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></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-atrial-fibrillation-rapid-ventricular-response-1&amp;title=ECG%20Basics%3A%20%20Atrial%20Fibrillation%20With%20a%20Rapid%20Ventricular%20Response"><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();
