Abstract： |
The present invention belongs to the field of medical test technology, and the T-wave alternation measuring method for sports electrocardiogram beings from the No.113 beat of electrocardiogram signal and analyzes in 16 beats as one analysis window unit. Maximum heart rate is first judged to estimate the noise level. The power spectrum is then analyzed and judged based on noise, whether to exist obvious RR interphase alternation is judged, and if no, the ratio of component at 0.25 and the alternative component before deducing noise level is calculated. When the ratio is smaller than some value, obvious T-wave alternation is considered found out. The method of the present invention solves the problem of detecting weak T-wave alternation signal for predicting malignant arrhythmia. |
