Abstract

The invention discloses a detection method and a detection system for detecting a peak point of T waves from electrocardio signals, and also provides an electrocardio monitoring system based on the detection method. The detection method at least comprises the following steps of: obtaining electrocardio signals from a data collection device; selecting the electrocardio signals corresponding to the T waves in the electrocardio signals from the obtained electrocardio signals; fitting the T waves by a preset function, wherein the preset function comprises characteristic parameters requiring to be solved; solving the characteristic parameters by the selected electrocardio signals to obtain the fitted function; and obtaining the peak point of the T waves from the fitted function. A technical measure of using the preset function for fitting the T waves to obtain the dummy peak point of the T waves is used, so the technical problem of poor consistency when the traditional method is used for detecting the peak point of the T waves can be solved, and the technical effect of higher measurement consistency of the peak pint of the T waves is obtained.

Description

Technical field

[0001] The invention relates to the field of physiological signal analysis and detection, and more specifically, to a detection system and a detection method for the peak point of T waves in an electrocardiogram signal, and an electrocardiogram monitoring system based on the detection method. Background technique

[0002] Generally speaking, the electrocardiogram is based on the electrical activity carried out in the cardiac muscle cells. An electrocardiogram detection device, such as a twelve-lead electrocardiogram detection device, can sense the electrocardiographic signals conducted to the body surface by the electrocardiographic activity through lead electrodes attached to specific positions of the human body. From the sensed ECG signal, the heart's motion trajectory during the cardiac cycle can be depicted. A typical cardiac cycle usually has specific characteristic waveforms, such as P wave, QRS complex, T wave, and U wave. These characteristic waveforms c...
