Problems solved by technology

[0005] On the other hand, conventionally, time / frequency analysis methods using electrocardiography (ECG) signals have been developed in relation to the location of atrial fibrillation, but the electrocardiography signal itself is exposed to noise, including limited data length and abnormality ( Non Stationary), so it is difficult to accurately detect the location where atrial fibrillation occurs, and the cost of the time / frequency analysis method itself is quite high. At the same time, there is a problem that it is impossible to detect a location with a high possibility of atrial fibrillation.

Abstract

A method for generating a heart model reflecting action potential duration restitution according to an embodiment of the present invention can visually output the maximum slope for the correlation between a relaxation period and an action potential duration at every point included in a three-dimensional heart model.

Description

technical field [0001] The invention relates to a heart model generation method and a generation device reflecting action potential time course recovery phenomenon. More specifically, the present invention relates to a heart model generation method and a generation device capable of visually outputting the maximum slope of the correlation between relaxation time and action potential time course at all points included in a 3D heart model, reflecting the action potential time course recovery phenomenon. Background technique [0002] Arrhythmia (Arrhythmia) refers to atrial fibrillation that makes it difficult to form electrical stimulation or fail to transmit stimulation normally in the heart, unable to continue regular contraction, abnormally fast or slow heartbeat, or symptoms that become irregular. Cause of sudden death or stroke. [0003] The treatment method for arrhythmia is similar to the high-frequency electrode catheter ablation surgery, which can prevent arrhythmia ...
