The following article has been published, where simultaneous atrial + ventricular
pacing was used in pts with Atrial Fibrillation:

and pacing in patients with acute myocardial infarction. PACE 2005;28:Suppl
1:S193-7.
In the discussion of the paper, the authors write that: “ In contrast to
exercise test and A pacing, simultaneous V+A pacing can be used to assess TWA
also in patients with atrial fibrillation and impaired AV nodal conduction.
This approach also eliminates retrograde atrial activation and/or random sinus
activity at descending portion of the T wave, which may obscure the TWA
analysis during ventricular pacing. The data obtained with V+A pacing were
similar to those measured during the bicycle exercise and A pacing “
