Title:
HEARTBEAT TAG DATA SEQUENCE GENERATION METHOD AND APPARATUS BASED ON MULTI-LEAD ELECTROCARDIOGRAM SIGNAL
Document Type and Number:
WIPO Patent Application WO/2022/073374
Kind Code:
A1
Abstract:
A heartbeat tag data sequence generation method and apparatus based on a multi-lead electrocardiogram signal. The method comprises: performing sampling, fragment partitioning, electrocardiogram feature data identification, and first data preparation processing on a multi-lead electrocardiogram signal to generate an encoded input three-dimensional tensor; identifying an R point data position of multi-lead data, and then performing second data preparation processing to generate a decoded R point position three-dimensional tensor; and using the decoded R point position three-dimensional tensor as a heartbeat sensitive attention processing layer calculation factor of a transformer model decoder unit, and inputting the encoded input three-dimensional tensor to a transformer model for calculation, so as to generate a heartbeat tag data sequence. The method performs improvement on the transformer model that is based on a self-attention processing mechanism, and increases a heartbeat sensitive attention processing layer to a decoder unit of the model, thereby improving the sensitivity of the model for heartbeat features.
