Atrial fibrillation with complete AV block e. Junctional rhythm with atrial premature beats. b. Atrial fibrillation with functional aberrancy (Ashmann's phenomenon). Ashmann's phenomenon occurs during atrial fibrillation because a random pause causes the bundle branches to take longer to recover, and so if a quick beat comes down the AV node it can conduction with a bundle branch block. This creates a characteristic "Long-Short" pattern as shown below. Sometimes a whole run of aberrant "Ashmann" beats can be seen, until the next pause in AV conduction, where the bundle branches recover and the QRS becomes narrow again. The most likely cause of the widened QRS complexes (marked with a "V") is: a. Sinus tachycardia with a run of non-sustained ventricular tachycardia. b.

AV Nodal Reentry Tachycardia d. Atrial fibrillation with an underlying bundle branch block e. Ventricular Tachycardia c. AV Dissociation is present. These are all good reasons to call this Ventricular Tachycardia. However, the HALLMARK of VT is AV Dissociation...that PROVES it's VT. You can see dissociated P-waves between beats 2 and 3 and again between beats 5 and 6 of the wide QRS run. What is the most specific finding that you can see to prove that the strip below is ventricular tachycardia? a. The QRS is wide. b. The rate of the wide complex run is faster than the sinus rate c. AV Dissociation is present. d. The QRS looks different from the underlying sinus rhythm. e. The PR interval of the first beat is too short for that P-wave to have conducted d. It is not preceeded by a "long-short" timing cycle. If it were aberrantly conducted atrial fibrillation (i.e. Ashmann's) then there would be a pause preceeding the beat before it ("long-short"). Therefore, since this specific pattern is absent, it is more likely ventricular tachycardia. All the other findings can also occur in aberrancy. What finding can you use to argue that the wide complex run seen below is more likely ventricular tachycardia? a. The QRS is wider than the other beats. b. The QRS appears different from the underlying AFib. c. It's rapid d. It is not preceeded by a "long-short" timing cycle. e. It's irregular c.

The initial beat is late-coupled, arising from the T-U complex. c. The QRS complexes get larger and smaller d. The patient is on medication or has electrolyte disturbances that affect myocardial repolarization e. A long QT interval is present e.
