Problems solved by technology

However, due to the large variability between the peak points of the T wave detected by each lead electrode and the waveform changes caused by the drug effect, the results measured by the traditional peak point detection method are consistent. bad

Embodiment Construction

[0022] Embodiments of the present invention relate to the analysis and detection of physiological signals, such as electrocardiographic signals. Electrocardiagram signal (ECG; also known as elektrokardigramm, EKG). The detection method disclosed in the specific embodiments of the present invention can be used to identify the characteristics of the electrocardiographic signal, so as to predict events related to the patient's physiological functions, especially future events. More specifically, the ECG monitoring system and method disclosed in the present invention use biomarkers related to ECG signals to identify heart-related effects. In a specific implementation, the ECG monitoring system can detect the peak point of the T wave in the ECG signal. The peak point of the detected T wave can characterize the ECG signal parameters related to specific cardiac electrical activity, so as to facilitate the evaluation of whether a specific drug will have a negative impact on the patie...

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 present invention relates to the field of physiological signal analysis and detection, more specifically, to a detection system and detection method for T wave peak points in electrocardiographic signals and an electrocardiographic monitoring system based on the detection method. Background technique [0002] In general, an electrocardiogram is based on the electrical activity going on within the heart muscle cells. An electrocardiographic detection device, such as a twelve-lead electrocardiographic detection device, can sense electrocardiographic signals transmitted to the body surface by electrocardiographic activity through lead electrodes attached to specific positions of the human body. From the sensed electrocardiographic signals, the movement trajectory of the heart in the cardiac cycle can be drawn. A typical cardiac cycle usually has specific characteristic waveforms, such as P waves, QRS complexes, T waves, and U waves. These character...
