Abstract

The invention relates to an improved electrocardiosignal quick clustering analysis method. The method includes steps: windowing electrocardiosignal, and preprocessing data in a window to remove interference; capturing a heart beat fragment from the preprocessed data, and performing time domain or frequency domain processing to obtain a new signal sequence; calculating a similarity coefficient of the sequence, comparing with a threshold to further perform heart beat classification, and extracting an average template of each type; moving the window to a next electrocardiosignal section, and repeating the process until the whole electrocardiosignal clustering is completed; subjecting the average templates obtained in each window to secondary clustering to obtain a final heart beat type and the heart beat quantity and the average template of the corresponding type. The method is suitable for short-term or long-term electrocardiosignals and also suitable for single-lead or multi-lead electrocardiosignals and can be used for electrocardiosignal quick clustering of normal sinus rhythm, single abnormal rhythm or various abnormal rhythms. The method can be popularized in electrocardiosignalactivation analysis and relevant quantitative research.

Description

technical field

[0001] The invention relates to an improved fast cluster analysis method for electrocardiographic signals. Background technique

[0002] ECG signals can comprehensively reflect the electrical activity of the heart, and play an important role in the diagnosis of heart disease and the evaluation of heart function. At present, ECG mapping technology is becoming more and more perfect, and it is more convenient to obtain human ECG signals before, during or after surgery, whether in or out of the hospital. Electrocardiogram has become a routine and important clinical examination method, which can assist doctors in diagnosing or evaluating patients. However, due to the wide variety of arrhythmias, and the ECG signals of patients may show different characteristics at different times, the individual differences are large, resulting in large variations in ECG signals, resulting in false detections. In addition, due to the low frequency and short duration of some abno...
