Heart electric defibrillation optimization method with patient individual electrode configuration

Abstract

A heart electric defibrillation optimization method with patient individual electrode configuration is applicable to an implanted cardioverter defibrillator (ICD) and is used for optimizing ICD electrode configuration and defibrillation function before a surgery so as to obtain an optimal individual heart electric defibrillation manner of a patient. The heart electric defibrillation optimization method comprises the following steps: S1, acquiring a medical image of a chest cavity of the patient; S2, reconstructing a three-dimensional heart-chest cavity anatomical model of the patient; S3, carrying out grid division on the model and loading conductivity to generate a heart-chest cavity numerical model; S4, simulating the surgery to implant an IDC defibrillation electrode system; S5, calculating an in-heart ICD defibrillation electric field; S6, evaluating an ICD defibrillation function according to the distribution of the electric field; and S7, repeating S4 to S6 and comparing and optimizing a plurality of different ICD electrode configurations to obtain the optimal individual heart electric defibrillation effect and defibrillation manner. Aiming at the patient, the ICD defibrillation is simulated and evaluated before the surgery and the implanting mode of the ICD electrode is optimized, and one set of the optimal ICD implanting reference scheme aiming at the patient is provided for clinic, so that the ICD surgery success rate and the defibrillation treatment effect are improved.

Description

technical field [0001] The invention belongs to the technical field of medical electronics, and specifically relates to an optimization method for cardiac electrical defibrillation with patient-individualized electrode configuration suitable for an implantable cardioverter-defibrillator (ICD). Background technique [0002] Sudden cardiac death (sudden cardiac death, SCD) refers to unexpected natural death caused by cardiac causes within 1 hour after the onset of acute symptoms, and its onset is usually unpredictable and without any warning. The prospective study of the national "Tenth Five-Year Plan" scientific and technological research project in 2009 shows that the incidence of SCD in my country is 41.84 / 100,000, and the total number is as high as 544,000 / year, ranking first in the world; in other developed countries, there are also several SCD occurs in the hundreds of thousands and accounts for about 50% of all cardiovascular deaths. Among them, ventricular fibrillation...
