下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
如背景技术所述,目前,现有的心电图自动诊断技术是对心电图的每个心搏的P波、QRS波和T波进行信息标注和特征提取。然而,在对P波,QRS波和T波的起止点标注的过程中,由于受到基线漂移噪声、肌电噪声、工频干扰以及其他突发噪声的影响,会导致检测结果的准确度与R波顶点相比有很大降低。
为了解决上述问题,本申请实施例提供了一种心电图数据处理的方法,如图1所示,所述方法包括:
101、获取样本心电图的所有心搏数据信息。
其中,所述心搏数据信息可以包括所述样本心电图中的波形数据信息。
102、根据预设的聚类合并算法,对所述心搏数据信息进行均值波处理,并将所述处理结果确定为所述样本心电图的均值波形。
其中,为了降低波形数据信息采集时的工频干扰,基线漂移等噪声,可以通过所述预设的聚类合并算法对上述样本心电图中的波形数据信息进行聚类合并,以获取该导联心电图的均值波形,所述均值波形可以体现大多数波形的共有特征,从而提高P波,QRS波,T波起止点标注的准确性。所述根据预设的聚类合并算法,对所述心搏数据信息进行均值波处理的具体过程可以包括:对所述获取的样本心电图的所有心搏数据信息依次进行R波检测、筛选处理和聚类合并,所得到的波形可以确定为所述样本心电图的均值波形。
需要说明的是,在现有技术中都是对全部心搏进行R波检测以及P波、QRS波、T波和ST段进行分析,并提取特征值。而本申请只需对所述合成的均值波形的P波、QRS波、T波和ST段进行分析和特征提取,可以极大地减少运算量,提高心电图数据分析和特征提取的效率。
103、对所述均值波形进行P波、QRS波、T波以及ST段的信息标注。
具体地,可以直接根据所述均值波形,以及所述P波、QRS波、T波以及ST段对应的形状特征进行识别,并根据所述识别结果对所述P波、QRS波、T波和ST段进行信息标注。需要说明的是,所述通过聚合心搏得到的均值波形可以体现大多数波形的共有特征,另外,由于心电信号比较微弱,在采集的时候容易受到工频干扰,基线漂移等干扰,会影响P波、QRS波、T波起止点标注的准确性,标注的位置也会随着干扰波动,而通过聚合心搏得到的均值波形,可以降低干扰,从而提高P波、QRS波、T波起止点标注的准确性。
104、输出标注后的P波、QRS波、T波以及ST段的波形信息。
具体地,根据上述对所述均值波形进行P波、QRS波、T波以及ST段的信息标注后,将所述标注的波形信息进行输出。
进一步的,为了更好的说明上述心电图数据处理方法的过程,作为对上述实施例的细化和扩展,本申请实施例提供了几种可选实施例,但不限于此,具体如下所示:
在本申请的一个可选实施例,所述步骤102具体可以包括:对所述心搏数据信息进行噪声处理,并对处理后的心搏数据信息进行R波检测,获取R波数据信息;根据所述R波数据信息,以及预设的筛选算法,对所述心搏数据信息进行筛选;对所述筛选结果进行聚类合并,并将所述聚类合并所得的结果确定为所述样本心电图的均值波形。其中,所述R波检测的具体过程可以包括:带通滤波:使用5-18Hz的前向滤波器对输入的心电图信号进行滤波并做相位延迟补偿;差分:对前向滤波器输出的信号进行差分处理,形成差分信号d(n);数据整理:对差分信号进行变换:输出d'(n)=输入的绝对值/G1;对经数据整理后的信号使用公式-d'(n)*d'(n)*log(d'(n)*d'(n))进行香农能量转换;平均滤波:使用滤波宽度M=55~75点(153~208ms)的前向滤波器对处理后的信号进行滤波并做相位延迟补偿;检测极大/小点:所述极大点是指取值大于位于其左右两侧的点的选定点,所述极小点是指取值小于位于其左右两侧的点的选定点;排除假R点;纠正误排除点;在近似R波位置周围±25点范围内寻找到真正R位置。
对于本申请实施例,所述对所述心搏数据信息进行噪声处理,具体可以包括:利用带通滤波对样本心电图数据进行噪声处理。
其中,通过带通滤波能够对基线漂移噪声、肌电噪声、工频干扰以及突发的噪声等进行滤波,实现提升P波、QRS波、T波的起止点标注的准确率。具体地,可以采用低频截止频率为14Hz,高频截止频率为20Hz的带通滤波在R波检测的时候进行滤波。针对基线漂移可以采用二阶中值滤波器,滤波后能有效的抑制基线漂移,且滤波后对ST段无明显变化。还可以采用自适应滤波器滤除心电信号中的50Hz工频干扰。
对于本申请实施例,所述根据所述R波数据信息,以及预设的筛选算法,对所述心搏数据信息进行筛选,具体可以包括:根据获取的所有心搏的RR间期数据信息,计算平均RR间期数据信息;根据所述平均RR间期数据信息,配置筛选区间,筛选RR间期数据信息处于所述筛选区间内的心搏数据信息。
其中,所述RR间期可以为当前R波与前一个R波顶点所在的位置差值,心率与RR间期成反比关系,具体换算公式可以为:
对于本申请实施例,平均RR间期可以为所有心搏的RR间期的平均值,配置所述平均RR间期的筛选区间,例如,可以选取0.8倍~1.2倍的平均RR间期作为筛选区间。
需要说明的是,聚合心搏以获取均值波形是为了合并多数属性相同的心搏,但对于偶发早搏,尤其是室性早搏,由于起搏点与其他心搏不同,即心搏的属性不同,可能会带来心搏的形状上的一些差异,如果参与叠加聚合,会对聚合心搏波形的准确性产生影响,因 此,所述偶发早搏不参与叠加聚合。
对于本申请实施例,所述对所述筛选结果进行聚类合并,并将所述聚类合并所得的结果确定为所述样本心电图的均值波形,具体可以包括:对所述筛选的心搏数据信息配置采样点,并对所有采样点进行叠加求均值处理;将处理所得结果确定为所述样本心电图的均值波形。
其中,可以对所述筛选的心搏数据信息配置采样点,并对所述采样点进行叠加求均值处理;将处理所得结果确定为所述样本心电图的均值波形。需要说明的是,R波两侧的叠加范围可以根据平均RR间期确定。如:平均RR间期为1000ms,则可以确定以R波顶点为中心点,对R-500ms~R+500ms范围内的采样点进行叠加求均值处理。
在本申请的一个可选实施例,为了得到所述均值波形的R波切迹、QRS波形态、QRS波电压变化信息,所述方法还可以包括:对所述均值波形进行波段分析,得到所述均值波形的R波切迹、QRS波形态、QRS波电压变化信息。
需要说明的是,在特征标注和提取方面,现有技术通常只关注QRS波的Q波,R波和S波的波电压以及QRS波时间等信息,而往往忽略了对于Q波,R波和S波每个波的时间,以及左右心室除极过程中的变化的信息的收集和分析。例如:左束支传导阻滞的QRS波前半部分形态和时间正常,后半部分时间延长以及QRS波的形态呈宽大、平顶或有切迹的R波,上述左束支传导阻滞的心电图特征在通过现有技术标注和提取的特征中无法得到体现;另外,现有技术对QRS波的形态关注不足,如右束支传导阻滞中的QRS波呈现“M”形态,而上述形态在通过现有技术标注和提取的特征中也无法得到体现。而本申请对QRS波的切迹、形态的判断以及电压变化过程的记录,使得上述心电图特征得以在AI预测中起到一定作用。
对于本申请实施例,所述对所述均值波形进行波段分析,得到所述均值波形的R波切迹、QRS波形态、QRS波电压变化信息,具体可以包括:根据所述均值波形,检测R波顶点两侧的拐点位置信息,并根据所述拐点位置信息,判断R波是否存在切迹;计算所述均值波形中QRS波过零点的数目,并根据所述数目,确定QRS波的形态;以所述均值波形中R波顶点为中心点,分别记录所述中心点两侧波形的电压变化过程。
其中,计算所述均值波形中QRS波过零点的数目,并根据所述数目,确定QRS波的形态的过程具体可以包括:计算所述均值波形中QRS波过零点的数目,并根据所述数目,确定QRS波的形态,所述QRS波可以呈现rsR’、RSR’或rR’形态。具体地,可以以R波顶点为中心,分别判断其左右两侧过零点的数目。例如,R波顶点左侧存在一个过零点,R波顶点右侧存在三个过零点,则可以判断QRS波形态为RSR’。
所述QRS波电压变化过程的记录方式可以包括:以所述均值波形中R波顶点为中心点,分别记录其两侧波形的电压变化过程,所述电压变化过程可以体现QRS波后半部分宽大顿挫的特点。具体地,可以以R波顶点为中心,每隔Nms(如10ms)取一个点。例如,采样率为500Hz,均值波形中R波顶点的位置为点x,均值波的电压为y
x,以均值波形的R波顶点为中心,向其左右两侧每隔10ms记录电压值为y
x+5、y
x-5、y
x+10、y
x-10……,横坐标的取值范围可以为x-0.1s~x+0.1s。
进一步地,所述根据所述均值波形,检测R波顶点两侧的拐点位置信息,并根据所述拐点位置信息,判断R波是否存在切迹,具体可以包括:对所述均值波形进行一阶差分处理,检测R波顶点两侧的拐点位置信息;将所述拐点位置信息与所述P波、QRS波、T波、ST段起止点位置信息进行对比;根据所述对比结果,判断R波是否存在切迹。
其中,所述判断R波是否存在切迹的具体过程可以包括:对所述均值波形进行一阶差分处理,检测R波顶点两侧的拐点,所述一阶差分就是对均值波形求x点与x+1点的电压差,如果均值波形的某点的左右两侧一阶差分的值正负相反,则可以判断该点为QRS波中的拐点;根据拐点的位置与P波、QRS波、T波起止点位置的对比结果,可以判断R 波是否有切迹。例如,若R波顶点与QRS波终点中间存在两个拐点,则说明该R波有切迹。
在本申请的一个可选实施例,为了利用数据处理后的心电图数据确定目标状态信息,所述方法还可以包括:当接收到心电图分析处理请求时,根据所述请求中携带的心电图数据信息,以及预先训练的目标状态识别模型进行预测分析,并输出分析结果,以确定目标状态信息,所述预先训练的目标状态识别模型的训练样本数据是通过均值波处理进行波段分析得到的。
具体地,接收心电图分析处理请求,所述请求中可以携带有所述心电图的数据信息;可以根据预先训练的目标状态识别模型进行预测分析,并输出分析结果,从而可以根据所述分析结果,对应确定目标状态信息。
本申请可以通过聚类合成均值波形,从而平滑滤波,有效地弱化基线漂移噪声、肌电噪声、工频干扰以及突发的噪声的影响,极大的提升对P波,QRS波和T波的起止点标注的准确率。
