窦性和房性心律失常的基本尺度熵检测

Detection of Sinus Arrhythmia and Atrial Arrhythmia Based on Base-Scale Entropy

文献指出,基本尺度熵方法可以应用于短时心率变异信号的分析。本文利用该方法,从数据库中提取窦性心律、房性心律失常的ECG信号,以实现该两种心律失常的检测。本文对MIT-BIH标准数据库中的正常窦性心律、房性早搏、窦性心动过缓信号进行了分析和检测。结果表明,基本尺度熵方法能够检测窦性和房性心律失常。

As is known in literature, the Base-scale Entropy Measure is useful for analyzing short-term heart rate variability signals. In this study, the method is applied to detect cardiac arrhythmias, including sinus and atrial arrhythmia. We detect and analyze normal sinus rhythm （NSR）, atrial premature contraction （APC） and sinus bradycardia （SBR） signals. The selected data of NSR are obtained from the MIT-BIH normal sinus database, while others are from the MJT-BJH arrhythmia database. The results show the Base-scale Entropy can also detect sinus and atrial arrhythmia.
