Why the study?
Diagnosis of atrial tachycardia with 3D mapping remains challenging due to fibrosis or previous ablation, prompting evaluation of a new window of interest setting adjusted at the end of the P wave.
Does an electroanatomical mapping annotation setting using a window of interest adjusted at the end of the P wave improve the accuracy of identifying the atrial tachycardia mechanism compared to conventional settings in patients undergoing left AT ablation?
Does an electroanatomical mapping annotation setting using a window of interest adjusted at the end of the P wave improve the accuracy of identifying the atrial tachycardia mechanism compared to conventional settings in patients undergoing left AT ablation?
Adjusting the window of interest to the end of the P wave during electroanatomical mapping significantly improves the accuracy and speed of diagnosing the mechanism of left atrial tachycardia.

May enhance left AT mechanism identification on mapping; leaves open prospective outcome trials before practice change.
