Description

technical field [0001] The invention belongs to the field of abnormal detection of electrocardiographic signals, in particular to a wearable device for electrocardiographic signals based on a joint neural network algorithm and an abnormal detection and analysis method. Background technique [0002] The ECG signal is drawn by the electric current generated by the heart activity and transmitted to the body surface. It can accurately reflect the activity state of the heart and is one of the important means for doctors to diagnose heart disease. ECG signal is a weak physiological signal with small voltage value and time interval. Therefore, extracting ECG signal features and assisting detection by computer can improve the efficiency of doctors' diagnosis. In recent years, with the continuous development and improvement of artificial intelligence algorithms, algorithms commonly used for ECG signal detection and classification are mainly divided into traditional machine learning m...
