| 摘 要： | ST段变化是心电图(ECG)检测心肌缺血(MI)主要的临床表现,受基线漂移、体位变化、电极等因素影响,给ST段的有效检测带来困难。目前ST段常用的检测方法有:R+x和J+x,但它们受T波形态变异影响很大,且J点定位也存在一定的难度。基于上述原因,本文提出了一种方便准确的T波起点检测方法,该方法不需定位T波峰点,且受基线漂移、T波变异等的影响很小。然后联合R波峰点和T波起点提出了一种ST段夹逼检测方法,经公共数据库Long-Term ST database(LTST)验证,该方法有很好的实时性和鲁棒性,且准确率能够达到92%以上。

| Abstract: | ST-segment is the main clinical appearance in myocardial ischemia detection based on electrocardiogram(ECG) signals.However,it is highly sensitive to interferences(baseline wandering,postural changes,electrode interference,etc.),which cause the feature points of ECG ST-segment to be difficult to detect accurately.Currently,the common detection methods of ST-segment are: R+x and J+x,but they are affected badly by T-wave morphological variability and J point location.For these reasons,firstly we proposed a co... |
