Low Voltage Areas in Left Atrium are Related to Delayed Invasive Care for Atrial Fibrillation

Abstract

Areas of low voltage electrograms (<0.5 mV) (LVA) are known to correlate with areas of atrial fibrosis and are related to clinical outcomes after ablation. We hypothesized that delay in seeking invasive treatment is linked to larger LVA.
