Although feedback mechanisms from mechanical response to electric activity have been suggested to be significant in cardiac muscles, its details remain unknown. This Mechano-Electric Feedback (MEF) was investigated using dynamic FEA. Cardiac muscle is modeled as incompressible hyperelastic material, which is generally analyzed by implicit methods. To reflect cardiac deformations in fine time intervals and couple mechanical and electrical activities, a new explicit method was constructed by applying decoupled FEM, which is generally used in fluid analysis. The proposed method successfully reproduced MEF and indicated that MEF can change the movements of spiral reentry.
