Implantation evaluation system of a fully subcutaneous implantable cardioverter-defibrillator s_icd

Abstract

An implantation evaluation system suitable for a fully subcutaneous implantable cardioverter-defibrillator S_ICD with the functions of ECG sensing and defibrillation discharge, adding a defibrillation sensitivity evaluation device and a comprehensive evaluation device for the implantation of a fully subcutaneous S_ICD , used to optimize the S_ICD electrode configuration before operation to achieve the optimal defibrillation discharge efficiency and defibrillation sensitivity. The system consists of S_ICD defibrillation efficacy evaluation system, body surface electrocardiogram measurement device, defibrillation sensitivity evaluation device and comprehensive evaluation device. The S_ICD implanted defibrillation efficacy evaluation system evaluates the defibrillation energy distribution under the implantation plan, the body surface ECG measurement device records the body surface ECG information, and the defibrillation perception sensitivity evaluation device performs heart rhythm recognition and analysis on the collected equivalent body surface ECG , comprehensive evaluation device analysis and determination of the patient's individualized optimal S_ICD electrode system configuration and implantation plan. The present invention can provide a set of optimal S_ICD implantation reference plan for clinics for individual patients, and improve the success rate of S_ICD operation and the effect of defibrillation treatment.

Description

technical field [0001] The invention belongs to the technical field of medical electronics, and is specifically an implantation evaluation system suitable for a fully subcutaneous implantable cardioverter-defibrillator S_ICD with functions of electrocardiographic sensing and defibrillation discharge, which can provide individualized Fully subcutaneous defibrillation electrode implantation optimization and best cardiac defibrillation effect. 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 ...

Problems solved by technology

[0006] The present invention aims at the deficiencies in the prior art, and aims to solve the blindness of the clinically implanted subcutaneous implantable cardioverter-defibrillator (S_ICD) implantation scheme and the lack of consideration of individual patient differences. Invented an implantation evaluation system suitable for the fully subcutaneous implantable cardioverter-defibrillator S_ICD with the function of electrocardiogram sensing and defibrillation discharge. The misperception rate of ECG, combined with the estimation of the internal distribution of the defibrillation energy of the electrode system, obtains the optimal S_ICD electrode system configuration and subcutaneous implantation plan for the individual patient, effectively improving the success rate and effect of defibrillation; the system It is mainly composed of S_ICD implanted defibrillation efficacy evaluation system, surface ECG measurement device, defibrillation sensitivity evaluation device and comprehensive evaluation device; The body surface ECG measurement device is used to record the body surface ECG information, the defibrillation sensitivity evaluation device is used to analyze the heart rhythm recognition sensitivity of the collected equivalent body surface ECG information, and the comprehensive evaluation device is used to Combining the above defibrillation energy distribution information, ECG information, and heart rhythm recognition sensitivity to obtain the patient's optimal defibrillation effect and the best sensory sensitivity, and finally determine the best individualized preoperative S_ICD electrode system configuration and subcutaneous implantation plan; The invention can simulate and evaluate S_ICD defibrillation before operation and optimize the implantation mode of S_ICD and electrode system for individual patients, especially some special populations, and provide a set of best S_ICD implantation reference schemes for individual patients in clinical practice, improving The success rate of S_ICD operation and the effect of defibrillation therapy
