Abstract

The invention discloses a ventricular ectopic beat detection method based on a 1D (Dimension) convolutional neural network. As the convolutional neural network is generally applied to the aspect of two-dimensional image processing and an electrocardiosignal belongs to a one-dimensional time sequence, the invention designs a one-dimensional convolutional neural network used for detecting ventricular ectopic beats specific to the characteristics of the electrocardiosignal; meanwhile, the invention gives specific partition parameters on the electrocardiosignal specific to the characteristics of the electrocardiosignal, and a series of single cardiac beat data obtained by partitioning a cardiac arrhythmias database is input a specially designed one-dimensional convolutional neural network to be trained. Compared with the past method, the ventricular ectopic beat detection method disclosed by the invention has stronger robustness and higher detection precision.

Description

technical field [0001] The invention belongs to the technical field of medical testing, in particular, more specifically, relates to a ventricular ectopic beat detection method based on a 1D (Dimension) convolutional neural network. Background technique [0002] In recent years, the fast-paced lifestyle has made people's life pressure increase year by year, and their health has attracted more attention. Heart disease has always been a serious threat to human health. With the development of social economy, people's lifestyle has undergone profound changes. Especially with the aging population and the acceleration of urbanization, the prevalence of cardiovascular diseases in China is on the rise, leading to a continuous increase in the number of cardiovascular diseases. The prevention and treatment of heart disease has always been a research hotspot at home and abroad. [0003] The electrocardiographic signal plays an important role in the research of clinical medicine. It c...
