摘要

•Intrinsic cardiac elastography measures wave speed in heart to estimate elasticity•Wave speed sensitivity to geometric variations in the heart is not well understood•Wave speed sensitivity to material and geometric parameters was studied•Intrinsic cardiac wave speed depends strongly on elastic modulus•Wave speed is insensitive to geometric heart chamber parameters
