Finite Element Simulation Study of the Localization of Bioelectric Current Source
Atrial fibrillation (AF) is a common cardiac rhythm disturbance that increases in prevalence with advancing age.To get the real time location of the related key lesions is of great significance to treat and abolish AF.2-dimensional finite element method was adopted to simulate the lead field.Based on the acoustoelectric effect and the reciprocal theory,the source density of the current field was calculated,thus determining the precise location of the current source and sink.Results show that the simulated positioning precision of current source and sink is within submillimetre only using a pair of recording electrode.This work implies that with the acoustoelectric effect method,it is promising to locate the key lesions from messy fibrillation.
