Improved Local Activation Time Annotation in Fractionated Atrial Electrograms of Atrial Mappings

MATLAB source code to reproduce the results in [1] by generating simulated atrial electrograms and implementing the proposed deconvolution approach to estimate local electrograms and LATs How to use it? in two steps: First simulate data by running "run_data_simulation.m". you can skip this part and use the simulated data in "data" folder to reproduce the images and results for tissue T4 in figure 2 of [1] Second run "run_transCurr_and_LAT_estimation.m" to implement deconvolution and LAT estimation,
