Abstract

The present invention belongs to the field of medical detection technology, and is the T-wave alternation detecting method and device for sports electrocardiogram. The method includes dividing into four stages of regulating one, first heart rate one, second heart rate one and restoring one; setting the sustaining period of each stage and controlling the moving speed and slope of the plate to makethe heart rate enter into the four stages successively and recording the electrocardiogram signal of both first heart rate stage and the second heart rate. The device includes connecting unit, input protector circuit, amplifier system, A / D converter, microcomputer and plate and plate control interface circuit. The present invention is used to detect T-wave alternation in microvolt level in T-wavealternation research and relevant clinical research.

Description

technical field [0001] The invention belongs to the technical field of medical detection, in particular to the design of a detection device for T wave alternation in exercise electrocardiograms. Background technique [0002] Malignant ventricular arrhythmia is a heart disease that poses a great threat to human life safety. It is a major factor in the loss of life in developed countries such as Europe and the United States. Therefore, the prediction of malignant ventricular arrhythmia in these countries has always been at the forefront Discussion questions. At present, the relatively accepted predictive method is electrophysiological examination of cardiac catheterization, which uses a programmed stimulator to deliver 2 or 3 electrical stimuli under program control to the right atrium through cardiac catheter electrodes. If ventricular tachycardia (VT) can be induced, then Indicates that there is a material basis for the occurrence of ventricular tachycardia and ventricular ...
