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 o… Show more
