We have previously presented an MR-compatible EP system designed for real-time MR imaging able to directly locate and characterize electrical properties of potential arrhythmogenic regions in the left ventricle (LV). Here we present our initial experience of ventricular endocardial local activation time (LAT) mapping during programmed stimulation performed in several porcine models.
