What are the electrophysiologic characteristics that distinguish atrial tachycardia originating from the right pulmonary veins versus the posterior right atrium?
P wave configuration in lead V1 and double potential characteristics from the posterior right atrium can accurately distinguish atrial tachycardia originating from the right pulmonary veins versus the posterior right atrium.
Yamada et al. (2004) studied this question.
