Tricks. &nbsp;We published it to this site three years ago, but believe it should be shown again, as it is somewhat rare to catch a good-quality 12-Lead ECG of an implanted cardioverter-defibrillator pacemaer using overdrive pacing to terminate a ventricular tachycardia. &nbsp;Most of our examples have been rhythm strips.</p><p>In this strip, we see the patient in ventricular tachycardia (V tach) at a rate of about 190 / minute. &nbsp;The ICD, in response to the fast rate, delivers a short burst of even faster paced beats. &nbsp;The physological rule in the heart is, "the fastest pacemaker controls the heart". &nbsp;Once the pacemaker has terminated the V tach, it paces at a much slower rate. &nbsp;It is pacing the atria, and the conduction system is intact, allowing the impulse to travel normally through the ventricles. &nbsp;If the sinus node is able to "outpace" the slower paced rhythm, the heart will resume a sinus rhythm.</p><p>This is called "overdrive pacing" and is done automatically by an ICD that is programmed to do so. &nbsp;Overdrive pacing can also be accomplished by a temporary transvenous pacer or transcutaneous pacemaker. &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/552/feed" method="post" id="fivestar-custom-widget--3" 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--6" name="vote" class="form-select"><option value="-">Select rating</option><option value="20">Give Anti-tachycardia Function of ICD 1/5</option><option value="40">Give Anti-tachycardia Function of ICD 2/5</option><option value="60">Give Anti-tachycardia Function of ICD 3/5</option><option value="80">Give Anti-tachycardia Function of ICD 4/5</option><option value="100" selected="selected">Give Anti-tachycardia Function of ICD 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >4.1</span></span> <span class="total-votes">(<span >9</span> votes)</span></div></div> </div> </div> </div><input class="fivestar-submit form-submit" type="submit" id="edit-fivestar-submit--3" name="op" value="Rate" /><input type="hidden" name="form_build_id" value="form-9m10cXFyGfK6LTQKOEej_hiWHv_g82lfaK17DiWdmLM" /> <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/icd" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">ICD</a></div><div class="field-item odd"><a href="/ecg/pacemaker" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Pacemaker</a></div><div class="field-item even"><a href="/ecg/anti-tachycardia" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Anti-tachycardia</a></div><div class="field-item odd"><a href="/ecg/overdrive-pacing" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Overdrive pacing</a></div><div class="field-item even"><a href="/ecg/ventricular-tachycardia" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Ventricular tachycardia</a></div><div class="field-item odd"><a href="/ecg/wide-complex-tachycardia-0" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Wide-complex tachycardia</a></div><div class="field-item even"><a href="/ecg/tachycardia" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">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_3"> <a class="a2a_dd addtoany_share_save" href="https://www.addtoany.com/share#url=https%3A%2F%2Fwww.ecgguru.com%2Fecg%2Fanti-tachycardia-function-icd&amp;title=Anti-tachycardia%20Function%20of%20ICD"><img src="/sites/all/modules/addtoany/images/share_save_256_24.png" width="256" height="24" alt="Share"/></a> </span> </span></li> </ul> Tue, 06 Jan 2015 08:53:57 +0000 Dawn 613 at https://www.ecgguru.com https://www.ecgguru.com/ecg/anti-tachycardia-function-icd#comments
