Abstract

The invention relates to an electrocardio data compression method, and the method comprises the following steps: collecting electrocardio data samples to establish an electrocardio data sample set, and establishing an alternative compression scheme space based on electrocardio data characteristics; based on the electrocardiogram data segment sample set and the alternative compression scheme space, carrying out deep reinforcement learning network training, and obtaining a compression scheme selection model; inputting electrocardio data to be compressed into the compression scheme selection model to obtain a matched compression scheme; and performing data compression on the to-be-compressed electrocardiogram data based on the matched compression scheme. According to the electrocardiogram data compression method, the characteristics of the electrocardiogram data are fully considered, the adaptability is high, and the compression ratio is high.

Description

technical field

[0001] The invention relates to the technical field of electrocardiographic data compression, in particular to a method, device and computer storage medium for electrocardiographic data compression. Background technique

[0002] Electrocardiographic examination has long been one of the routine examination techniques in clinical medicine. Wherever there is medical activity, there is an electrocardiogram. According to the requirements of the American Heart Association (AHA), an ECG signal must be composed of 3 separate leads, the resolution of the ADC is 10 bits, and 500 samples per second need to be recorded. Some special ECG examinations, such as dynamic ECG, may require 12 leads, the ADC resolution is 11 bits, records 1000 samples per second, and the continuous recording time exceeds 24 hours. If this ECG signal were converted to a digital format, the computer storage space required for a single ECG recording would exceed 1.32GB.
