Abstract
The present invention discloses a cardiac transmembrane potential reconstruction method based on a graph convolutional neural network and an iterative threshold contraction algorithm. The cardiac transmembrane potential is econstructed iteratively through the iterative threshold contraction algorithm embedded in the graph convolutional neural network, and the graph convolutional neural network is used to extract the correlation information between nodes in the non-Euclidean dat a of the cardiac transmembrane potential, while retaining the rigorous mathematical calculations of the iterative threshold contraction algorithm, a solution og the cardiac transmembrane potential is obtained after multiple iterations. Based on the reconstructed temporal and spatial sequence of the cardiac transmembrane potential, the present invention can assist in the diagnosis of common heart diseases such as premature ventricular beats, tachycardia, atrial fibrillation, myocardial ischemia and myocardial infarction in arrhythmia, and is useful for subsequent treatment and provide guidance for radiofrequency ablation surgery.
