Comparison of Voltage Map Calculation Methods Using Non-Fractionated EGM Signals in a Persistent AF Patient

Catheter ablation targeting low voltage areas (LVA) is commonly being used to treat atrial fibrillation (AF) in patients with persistent AF. However, it is not always certain that the areas marked as low voltage (LV) are correct. This can be related to how the voltage is calculated. Therefore, this paper focuses on comparing different calculation methods, specifically, with regards to spatial distribution.Two voltage maps obtained in AF were...
