From the information/hint below, can you identify the

Decapolar catheters were placed in the region of the
crista terminalis and in the coronary sinus. A #7 Fr 3.5mm ablation catheter
was placed along the eustachian ridge.
The electrogram below was recorded with the catheters
in place.
The cycle length of the tachycardia is 243mS with 3:1
A-V conduction.

Entrainment of the tachycardia from mid-CS revealed a
return cycle length of 286mS.
