Sometimes, the premature beat feels much weaker due to less filling time available to the ventricles. &nbsp;Atrial bigeminy can have very benign causes, such as increased caffeine intake, or it can have more complex causes such as advanced heart disease or conduction blocks. &nbsp;In some patients, atrial bigeminy, or any PACs, can be a precursor to more serious atrial dysrhythmias, such as atrial fibrillation.</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/820/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: Sinus Rhythm With Atrial Bigeminy 1/5</option><option value="40">Give ECG Basics: Sinus Rhythm With Atrial Bigeminy 2/5</option><option value="60">Give ECG Basics: Sinus Rhythm With Atrial Bigeminy 3/5</option><option value="80" selected="selected">Give ECG Basics: Sinus Rhythm With Atrial Bigeminy 4/5</option><option value="100">Give ECG Basics: Sinus Rhythm With Atrial Bigeminy 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >3.4</span></span> <span class="total-votes">(<span >8</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-sksDq9RiysZ4HoAKsnt4R-fSF7Y9135dx-0BL44HWKw" /> <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/rhythm-strip" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Rhythm strip</a></div><div class="field-item odd"><a href="/ecg/sinus-rhythm" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Sinus rhythm</a></div><div class="field-item even"><a href="/ecg/atrial-bigeminy" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Atrial bigeminy</a></div><div class="field-item odd"><a href="/ecg/pacs" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">PACs</a></div><div class="field-item even"><a href="/ecg/premature-atrial-contractions" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Premature atrial contractions</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-sinus-rhythm-atrial-bigeminy&amp;title=ECG%20Basics%3A%20%20Sinus%20Rhythm%20With%20Atrial%20Bigeminy"><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> Sun, 30 Jun 2013 07:22:29 +0000 Dawn 459 at https://www.ecgguru.com https://www.ecgguru.com/ecg/ecg-basics-sinus-rhythm-atrial-bigeminy#comments
