A biomedical simulation system comprising: biomedical information storing means for storing biomedical information specific to a patient; simulation execution determining means for determining, based on the biomedical information, whether to perform biomedical simulation; model generating means for generating a biomedical model of a heart of the patient based on the biomedical information when the simulation execution determining means has determined to perform the biomedical simulation; simulation executing means for executing, based on the biomedical model generated by the model generating means, the biomedical simulation of post-operative conditions of the heart following an operation to implant a cardiac resynchronization therapy device performed on the patient, for each of a plurality of electrode disposition patterns associated with implantation of the cardiac resynchronization therapy device; improvement rate determining means for determining whether results of the biomedical simulation executed by the simulation executing means meet a predetermined improvement rate associated with symptoms; treatment expense reimbursing means for determining, when the improvement rate determining means has determined that the results of the biomedical simulation do not meet the predetermined improvement rate, not to reimburse medical treatment costs for the operation of the patient; and operation decision-making means for deciding to perform the operation on the patient when the improvement rate determining means has determined that the results of the biomedical simulation meet the predetermined improvement rate. biomedical information storing means for storing biomedical information specific to a patient; simulation execution determining means for determining, based on the biomedical information, whether to perform biomedical simulation; model generating means for generating a biomedical model of a heart of the patient based on the biomedical information when the simulation execution determining means has determined to perform the biomedical simulation; simulation executing means for executing, based on the biomedical model generated by the model generating means, the biomedical simulation of post-operative conditions of the heart following an operation to implant a cardiac resynchronization therapy device performed on the patient, for each of a plurality of electrode disposition patterns associated with implantation of the cardiac resynchronization therapy device; improvement rate determining means for determining whether results of the biomedical simulation executed by the simulation executing means meet a predetermined improvement rate associated with symptoms; treatment expense reimbursing means for determining, when the improvement rate determining means has determined that the results of the biomedical simulation do not meet the predetermined improvement rate, not to reimburse medical treatment costs for the operation of the patient; and operation decision-making means for deciding to perform the operation on the patient when the improvement rate determining means has determined that the results of the biomedical simulation meet the predetermined improvement rate.
