Electrode implantation evaluation device and system for implantable cardioverter defibrillator icd

Abstract

The invention belongs to the technical field of medical electronics, and specifically relates to an electrode implantation evaluation device and system for an implantable cardioverter-defibrillator ICD, in particular, it is used for quantitative evaluation of defibrillation efficacy and individualized implantation optimization of ICD electrodes. The system consists of an electrophysiological measurement device, an image segmentation and reconstruction platform, an interactive electrode loading platform, and a defibrillation performance evaluation platform, supplemented by nuclear magnetic resonance (MR) equipment (or computerized tomography (CT) equipment) and X-ray machine. The electrophysiological measurement device detects the patient's chest impedance and ECG information, and the MR machine (or CT machine) and X-ray machine collect the patient's heart-chest image and the implanted ICD electrode image respectively, combined with the image segmentation and reconstruction platform, The processing and analysis of the interactive electrode loading platform and the defibrillation efficacy evaluation platform determine the best preoperative ICD electrode configuration scheme and intraoperative implantation position. The invention helps doctors optimize the design of ICD electrode implantation for individual patients and improves the ICD defibrillation treatment effect.

Description

technical field [0001] The invention belongs to the technical field of medical electronics, and in particular relates to an electrode implantation evaluation device and system of 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. Ventricular fibrillation (ventricular fibrillation-VF, referred to as ventricular fibrillation) is the most common cause of SCD among malignant arrhythmias. It has caused more than 300,000 cases of SCD in the United States in just one year, accounting for...
