Photon scattering effects in optical mapping of propagation and arrhythmogenesis in the heart
MJ Bishop‚ DJ Gavaghan‚ NA Trayanova and B. Rodriguez
Abstract
Background: Optical mapping is a widely used experimental tool providing high-resolution recordings of cardiac electrical activity. However, the technique is limited by signal distortion due to photon scattering in the tissue. Computational models of the fluorescence recording are capable of assessing these distortion effects, providing important insight to assist experimental data interpretation.Methods: We present results from a new panoramic optical mapping model, which is used to assess distortion in ventricular optical mapping signals during pacing and arrhythmogenesis arising from 3-dimensional photon scattering.Results/Conclusions: We demonstrate that accurate
