Jan 21st, 2023 - Accelerated idioventricular rhythm (AIVR) is a wide QRS complex dysrhythmia that, as far as pediatric population is concerned, occurs mostly in children with underlying systemic or heart disease. Its clinical course is thought to be typically beni...

Dec 20th, 2022 - Accelerated idioventricular rhythm has been documented in several cases involving the induction of general anesthesia; however, it has not previously been known to occur during reversal of neuromuscular blockade with neostigmine and glycopyrrolate...

Aug 22nd, 2022 - Background Accelerated idioventricular rhythm (AIVR) was first described by Sir Thomas Lewis in 1910. [1] AIVR is currently defined as an enhanced ectopic ventricular rhythm with at least 3 consecutive ventricular beats, which is faster than norma...

Aug 22nd, 2022 - Diagnostic Considerations Accelerated idioventricular rhythm (AIVR) is diagnosed based on its characteristic electrocardiography findings. Its main differential diagnosis includes slow ventricular tachycardia, complete heart block, junctional rhyt...

Dec 18th, 2014 - Discussion The initial three quarters of the tracing in Figure 1 could be either ventricular bigeminy with a pseudo-delta wave or ventricular preexcitation of every other beat. Luckily, the last three beats (V4, 5, and 6) prove that it is ventricu...

Feb 14th, 2014 - Explanation The deeply negative initial deflections, which are wide in the inferior leads, certainly suggest an old inferior infarction. Combined with tall R waves in the right precordial leads, these deflections can make one consider an old infer...

Aug 14th, 2013 - Answer Discussion The rhythm is sinus, which speeds up slightly during the second to fourth beats from the end. The QRS complexes are wide even for the right bundle branch block, which is present. The PR interval is long. More specifically, T wave...

Dec 17th, 2007 - Question Why is the QRS complex morphology changing? A) Intermittent Wolff-Parkinson-White (WPW) syndrome B) Intermittent accelerated idioventricular rhythm C) Intermittent left bundle branch block
