Abstract: Background: The misinterpretation of activation propagation within low voltage zone (LVZ) can complicate atrial tachycardia (AT) mechanism analysis, especially in patients with remodeled atrial substrate. This study investigated the impact of low voltage threshold adjustment (LVTA) on left atrial (LA) tachycardia activation mapping interpretation. Methods: We identified 55 ATs in 42 patients undergoing catheter ablation for LA tachycardia, with a mean LA voltage of
