Non-invasive arrhythmia treatment system

Abstract

The invention discloses a non-invasive arrhythmia treatment system, which comprises an imaging device, a processing device and a gathered energy transmission device. The imaging device is used for imaging an object to be treated to construct three-dimensional heart and body models of the object to be treated. The processing device comprises a body surface electric signal acquisition module, an electric activity computation module and an arrhythmia determination module. The body surface electric signal acquisition module is used for acquiring body surface electric signals detected by a plurality of electrodes which are placed at a plurality of positions on a body surface. The electric activity computation module is used for computing electric activities in the internal three-dimensional space of the heart through an inverse problem based on the acquired body surface electric signals and the three-dimensional heart and body models. The arrhythmia determination module is used for determining at least one origin position of arrhythmia at least based on the electric activities in the internal three-dimensional space of the heart obtained through computation. The gathered energy transmission device is used for transmitting gathered energy to the determined origin position to ablate cardiac muscle tissues at the origin position.

Description

technical field [0001] The invention relates to a system for treating abnormal electrophysiological signals, in particular to a system for treating arrhythmia. Background technique [0002] Traditionally, there are two main means of treating arrhythmia: one is drug therapy, and the other is medical catheter therapy. For drug therapy, by taking specific drugs, it is possible to control and maintain sinus rhythm and prevent stroke caused by arrhythmia attacks. However, since the efficacy of drug therapy is relatively low, and drug therapy may bring about some adverse side effects, in some cases, medical catheters are tried instead of drugs to treat arrhythmias. Medical catheter-based arrhythmia treatment involves the following operations: inserting a medical catheter into a blood vessel at the groin or neck position; slowly guiding the medical catheter to the heart along the path extending from the blood vessel. The end of the medical catheter is generally equipped with spec...

AI Technical Summary

Problems solved by technology

However, there are at least the following technical problems in the treatment of arrhythmia based on medical catheters: first, medical catheters are mostly disposable consumables, and the cost is expensive, and there is a lot of waste in long-term use; second, the treatment process is invasive, which may cause Discomfort or pain, possible infection, and relatively long hospitalization
