Question

True or False: Due to the speed of accelerated idioventricular rhythm, the QRS complexes in this rhythm do not have the classic ventricular wide and bizarre appearance.

Answer 1

True. Accelerated idioventricular rhythm (AIVR) is a cardiac rhythm disturbance that typically occurs in the setting of acute myocardial infarction or ischemia. The QRS complexes in AIVR appear wide and bizarre.

Step-by-step explanation:

True.

Accelerated idioventricular rhythm (AIVR) is a cardiac rhythm disturbance that typically occurs in the setting of acute myocardial infarction or ischemia. AIVR is characterized by a ventricular rate between 60 and 120 beats per minute. The QRS complexes in AIVR appear wide and bizarre, which is different from the classic narrow QRS complexes seen in normal sinus rhythm.
