Method for synchronously outputting electrocardiogram and vectorcardiogram

Abstract

The invention discloses a method for synchronously outputting an electrocardiogram and a vectorcardiogram. The method comprises the following steps of: connecting Wilson twelve-lead and frank-lead electrodes to a human body; acquiring an electric signal of the electrocardiogram and an electric signal of the vectorcardiogram respectively at the same time to establish a database; processing data in the database by a multiple linear regression mathematical model to evaluate a back projection matrix so as to establish a back projection method; processing the electrocardiosignal acquired by the Wilson twelve-lead electrode through amplifying filter protective isolation and a digital-to-analog circuit; inputting the processed electrocardiosignal into an embedded control system to perform back projection calculation; and outputting the electrocardiogram and the vectorcardiogram synchronously. In the method, an electrocardial vector signal with the same time as that of the electrocardiosignalis acquired through the back projection of the directly-measured electrocardiosignal by a back projection method, so that the electrocardiogram and the vectorcardiogram with the same time are output synchronously; and synchronous detection does not need to switch lead modes, so the cost is reduced and the method is easy and convenient to operate.

Description

technical field [0001] The invention relates to a method for realizing the output of electrocardiogram, in particular to a method for realizing synchronous output of electrocardiogram and electrocardiogram vector diagram. Background technique [0002] Electrocardiogram means that the heart is excited successively by the pacemaker point, atrium, and ventricle in each cardiac cycle, accompanied by the change of bioelectricity in the electrocardiogram, and various forms of potential changes are drawn from the body surface through the electrocardiograph (referred to as ECG). The electrocardiogram is an objective indicator of the occurrence, propagation and recovery process of cardiac excitement. The ECG is mainly based on the fact that the direction and size of the electrical excitation of the heart are different at each moment. It is a special inspection that records the three-dimensional direction and size of the electrical excitation generated by the heart at each moment. ...

[0004] But ECG and ECG vector Figure II The lead system of patients is different. Combining the conventional 12-lead ECG and the Frank lead ECG vector must use the ECG machine and the ECG vector machine respectively, and the replacement of the leads at the same time has brought a lot of inconvenience to the clinic.

At the same time, the synchronous electrocardiogram machine currently used mainly adopts the combination of the conventional 12-lead electrocardiogram and the Frank lead electrocardiogram to synchronously display the electrocardiogram and the electrocardiogram vector diagram. Although this detection device can realize the detection Synchronization of signals, but correlation, complex lead methods, inconvenient operation, and high price, all of which hinder the widespread use of vector cardiogram in clinic
