May differentiate AVNRT circuit types during mapping; extends activation pattern data but leaves clinical utility open.
What are the coronary sinus activation patterns in patients with anterior versus posterior AVNRT circuits?
Anterior AVNRT circuits are characterized by an initial slow wave followed by a rapid wave in the coronary sinus, reflecting early far-field left atrial involvement, whereas posterior circuits show early rapid waves compatible with early right atrial activation.
Yagi et al. (2007) studied this question.
