Systems and methods for generating an electromechanical map are disclosed herein. The methods includes obtaining ultrasound data comprising a series of consecutive image frames and radio frequency (RF) signals corresponding to the location in the heart； measuring displacements and strains based on the ultrasound data to determine an electromechanical activation in the location； converting the ultrasound data into a series of isochrone maps； and combining the series of isochrone maps to generate the electromechanical map. The electromechanical map illustrates the electromechanical activation and internal wall structures of the heart.
