心电图记录着人体心脏的生理电活动，其中蕴含着丰富的反应心脏节律及其电传导性的生理和病理信息，是诊断心脏疾病、评价心脏功能的重要依据之一。故医生在进行临床诊断时，通常需要查看心电波形的平均模板，进而基于该平均模板的参数进行诊断。
目前，电脑端根据获取到的心电图机采集到的心电波形计算出平均模板，并在电脑端显示平均模板波形。根据上述方式，用户需要在采集完心电波形后，再通过电脑端对平均模板波形的相关参数进行测量、校准以及修改，可见，上述操作较为复杂。此外，有时会出现基准线定位不准，从而导致根据基准线测量的相关参数值不准的问题。

【具体实施方式】
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1a至图3，图1a示出了本申请心电波形的数据测量方法第一实施例的流程示意图，图1b示出了本申请心电波形的数据测量方法第一实施例步骤S101的流程示意图，图2示出了本申请第Ⅱ导联的平均模板波形的显示界面示意图，图3示出了本申请全部导联的平均模板波形的显示界面示意图。本实施的方法可以包括以下步骤：
步骤S101：心电图机对心电波形进行处理，得到心电波形对应的平均模板波形。
其中，本实施例中的心电图机具有计算能力，可以直接对采集到的心电波形进行处理，得到该心电波形对应的平均模板波形。
具体地，结合参阅图1b，步骤S101可以包括以下子步骤S1011和S1012：
步骤S1011：获取心电波形上的多个有效QRS波形。
例如，心电图机获取心电波形上的多个有效QRS波形，其中心电图机可以根据预设算法直接筛选出完整的、正常的QRS波形，其中完整的QRS波形可以是包含P波、Q波、R波、S波和T波的波形，正常的QRS波形可以是连续的波形或特征值在预设范围内的波形。
此外，由于无效QRS波形的数量一般要远远小于有效QRS波形的数量，所以为了简便算法步骤，可以通过预设算法判断出无效QRS波形，将其排除，从而将剩余的QRS波形作为有效的QRS波形。其中，可以通过判断QRS波形是否完整，进行QRS波形的无效判断。一般地，由于心电图机开始和结束采集心电波形的时间点不一定是QRS波形的有效起点和终点，所以采集到的心电波形中的第一个QRS波形和最后一个QRS波形可能是不完整的心电波形，故可以将该不完整的QRS波形判断为无效QRS波形并将其排除，保留其他有效的QRS波形。另外，由于被采集者在初始采集心电波形时情绪紧张，导致初始采集的QRS波形为异常QRS波形，且会持续一段时间，所以可以通过预设算法将情绪紧张型的QRS波形判断出来，并将其排除；或者直接将在开始预设时间段QRS波形判断为无效QRS波形并将其排除。
步骤S1012：基于多个有效QRS波形对应点的幅值，得到心电波形的平均模板波形。
在获取该心电波形上的得到多个有效QRS波形之后，获取该多个有效QRS波形对应点的幅值，将多个有效QRS波形对应点的幅值进行取平均值或取中值，以作为该心电波形的平均模板波形的对应点的幅值。例如，将多个有效QRS波形的波峰点的幅值进行取平均值，作为该心电波形的平均模板波形对应波峰点的幅值，同理可以将多个有效QRS波形的波谷点的幅值进行取平均值，作为该心电波形的平均模板波形对应波谷点的幅值。除波峰点和波谷点外，心电波形的平均模板波形的其他对应点的幅值也可以采用多个有效QRS波形对应点的幅值进行取平均值或取中值的方式获得，在此不做赘述。
在一些实施例中，步骤S1012可具体包括：获取多个有效QRS波形上对应点的幅值的平均值，以作为平均模板波形上对应点的幅值。
一般地，心电波形可以包括起点、终点、波峰、波谷。具体地，可以是将获取到的多个有效QRS波形进行对准，即多个有效QRS波形的起点和终点相同，获取对应同一时间点的多个有效QRS波形的幅值，计算出该时间点对应的多个有效QRS波形的幅值的平均值，将该平均值作为该时间点对应的平均模板波形的幅值。根据该方法对应计算所有时间点对应的平均模板波形的幅值，以得到心电波形的平均模板波形。
在另一些实施例中，步骤S1012可具体包括：将多个有效QRS波形按照幅值大小进行排序，取处于中间位置的有效QRS波形作为心电波形对应的平均模板波形。
具体地，可以是将获取到的多个有效QRS波形进行对准，即多个有效QRS波形的起点和终点相同，将一时间点对应的多个有效QRS波形的幅值根据由大到小或由小到大的顺序进行排序，取处于中间位置的有效QRS波形作为心电波形对应的平均模板波形。其中，该时间点可以是随机选取或预先设定的。
其中，上述排序方式包括两种情况，一种情况：若多个有效QRS波形为奇数个有效QRS波形时，此时处于中间位置的有效QRS波形只有一个，即可以直接选取该有效QRS波形作为心电波形对应的平均模板波形；另一种情况：若多个有效QRS波形为偶数个有效QRS波形时，此时处于中间位置的有效QRS波形有两个，一种实施方式是选取其中一个有效QRS波形作为心电波形对应的平均模板波形，另一种实施方式是将该两个有效QRS波形上对应点的幅值的平均值作为平均模板波形上对应点的幅值，以得到心电波形的平均模板波形。需要说明的是，得到平均模板波形的方法有多种，不限于上述步骤S1012描述的方式。
在一些实施例中，心电图机可以采集得到多导联心电波形。其中多导联可以包括是3导联、5导联、12导联、15导联以及18导联等，在此不做限定。对应地，本步骤S101可具体包括：对多导联心电波形中的每导联心电波形进行处理，得到每导联心电波形对应的平均模板波形。其中，可对每导联心电波形执行上述步骤S1011和S1012以得到每导联心电波形对应的平均模板波形，此处不做赘述。步骤S102：在显示界面上显示平均模板波形。
本实施例中，心电图机可以包括至少一个显示界面，该显示界面用于显示平均模板波形。例如，心电图机设有触控显示屏，通过该触控显示屏显示的界面即为该显示界面。
多导联心电波形可对应存在多个平均模板波形，心电图机可提供波形选择区给用户选择要显示的平均模板波形，进而显示用户选择的平均模板波形。其中，心电图机可以包括至少 一个显示界面。如图2和图3所示，显示界面可以包括波形选择区201和波形显示区202。波形选择区201和波形显示区202的区域比例和相对位置可以根据实际情况进行调整。可选地，波形选择区201和波形显示区202的区域比例可以为1:4。
在显示界面的波形选择区201中显示有多个波形略缩图，其中，多个波形略缩图可以包括每个导联心电波形的平均模板波形略缩图(如图2的波形选择区201中的第I导联的平均模板波形略缩图、第II导联的平均模板波形略缩图、第III导联的平均模板波形略缩图……)、所有导联心电波形的平均模板波形进行叠加得到的略缩图(如图2的波形选择区201中ALL导联的平均模板波形叠加略缩图)。其中，波形略缩图中包括了导联的名称和该导联对应的平均模板波形。检测到用户在波形选择区201中对一波形略缩图的选择信号，将选择的波形略缩图对应的平均模板波形在波形显示区202中显示。其中，用户可以通过波形略缩图直观的查看到波形，以方便用户快速、准确地选择所需要查看的平均模板波形。可选地，当再次检测到用户在波形选择区201中对该波形略缩图的选择信号时，对该波形显示区202中显示的心电波形的平均模板波形进行隐藏，以防止隐私信息被泄露。例如，当医生不需要查看心电波形时，可以将波形显示区202中显示的波形进行隐藏，以防止隐私信息被泄露。
其中，上述选择信号可以是滑动信号，当检测到用户的滑动信号时，对不同平均模板波形进行切换显示。其中，可以根据用户在波形显示区202中产生的触摸点的移动轨迹，对波形进行切换显示。如图2所示，波形显示区202当前显示的波形为第II导联的平均模板波形，当检测到用户的触摸点向右移动时，依次显示触摸点所在波形缩略图对应的平均模板波形，即依次显示第III导联的平均模板波形、AVR导联的平均模板波形等等；同理检测到用户的触摸点向左移动时，依次显示第I导联的平均模板波形、ALL导联的平均模板波形，触摸点最终停留的波形缩略图对应的平均模板波形，为最终显示的平均模板波形。移动轨迹可以是非闭合轨迹和闭合轨迹。非闭合轨迹例如是预设长度的线段，闭合轨迹例如是圆形、长方形、三角形等。本申请所有实施例中的触摸点可以是由用户的手指或具有指示功能的操作工具触摸显示界面所产生的。这里的用户可以包括心电波形的采集者或被采集者或者其他人员，这里的具有指示功能的操作工具可以包括鼠标、激光笔或触控笔等。
基于用户在显示界面上的选择操作，在显示界面的波形显示区202显示至少一个导联心电波形的平均模板波形。可选地，以Q波的起点为基准点作一平行线，建立基线。其中，每个待显示导联的平均模板波形在显示界面中的基线位置相同，即是每个待显示导联的平均模板波形在显示界面显示时，对应Q波的起点在显示界面中的位置相同。
本实施例中，心电图机还可对平均模板波形进行测量得到测量值，并可以基于测量值进行分析得到分析结果，在显示界面上显示该测量值和/或分析结果。
在此实施例中，心电图机可以直接对心电波形进行处理，得到心电波形对应的平均模板波形，并在该心电图机显示界面上显示平均模板波形，便于用户在通过心电图机采集心电波形后可以直接在心电图机上查看平均模板波形；其次，由于不再需要将心电波形传输到电脑端，可以避免因为传输过程中出现问题，例如网络信号不佳，而导致的用户无法查看平均模板波形的情况的发生；再次，通过缩略图的形式在波形选择区中显示所有导联的平均模板波形，使得用户可以更加直观的选取需要查看的平均模板波形。
针对上述实施例中在显示界面显示的平均模板波形，心电图机提供对显示的平均模板波形进行缩放、基准线重定位等功能。具体可参阅下面方法实施例。
请参阅图4和图5，图4示出了本申请心电波形的数据测量方法第二实施例的流程示意图，图5示出了本申请第Ⅱ导联的平均模板波形放大后的显示界面示意图。本实施例的方法可以包括以下步骤：
步骤S201：心电图机对心电波形进行处理，得到心电波形对应的平均模板波形。
步骤S202：在显示界面上显示平均模板波形。
其中，步骤S201、S202的相关说明可参阅上述实施例步骤S101、S102，在此不做赘述。
步骤S203：响应于用户对显示界面进行的预设操作，对显示界面上显示的平均模板波 形进行相应缩放处理。
心电图机可以包括触摸显示屏，该显示界面为触摸显示屏的显示界面。其中，响应于用户在显示界面上进行的预设操作，可以对显示界面上显示的平均模板波形进行相应缩放处理。可选地，显示界面上可以实时显示放大或缩小的倍数。具体地，预设操作可以为以下至少一种：点击显示界面上的预设图标、单击显示界面上显示的平均模板波形、双击显示界面上显示的平均模板波形、触摸显示界面以在显示界面上形成两个进行靠近或远离的触摸点。
例如，预设图标可以包括放大图标和缩小图标。放大图标用于将平均模板波形进行放大显示，缩小图标用于将平均模板波形进行缩小显示。例如，心电图机响应于用户在显示界面上点击放大图标，将显示界面上显示的平均模板波形进行放大处理，响应于用户在显示界面上点击缩小图标，将显示界面上显示的平均模板波形进行缩小处理。
又例如，在单击或双击显示界面上显示的平均模板波形进行缩放的情况下，波形的缩放可以是在一定预设范围内。具体地，响应于用户单击或双击显示界面上显示的平均模板波形，将显示界面上显示的平均模板波形进行放大处理，当到达放大阈值后，继续对应单击或双击显示界面上显示的平均模板波形，可以将显示界面上显示的平均模板波形停止放大处理或者进行缩小处理。在其他实施方式中，还可以通过单击或双击显示界面上显示的平均模板波形直接显示其预设缩放大小的平均模板波形。
再例如，可以通过两个触摸点的靠近和远离对应将平均模板波形进行缩小和放大显示。用户触摸显示界面，在显示界面上形成两个触摸点，响应于用户在显示界面上的两个触摸点进行靠近，可以对显示界面上显示的平均模板波形进行相应缩小处理；响应于用户在显示界面上的两个触摸点进行远离，可以对显示界面上显示的平均模板波形进行相应放大处理。可以理解的是，对应于预设操作的缩放处理还有多种组合，此处不做赘述。
可选地，如图5所示，放大显示平均模板波形的波形显示区可以占据整个显示界面，以通过整个波形显示区显示放大后的平均模板的波形，从而便于用户查看平均模板波形或对平均模板波形进行其他操作。此时，显示界面上可以设置测量尺图标。用户点击测量尺图标，将测量尺显示在平均模板波形的相应位置，以对在放大后的平均模板波形进行测量，得到特征参数值。例如，特征参数值可以是时限、幅值、心率等。
在一些实施例中，心电图机还可以包括恢复图标。该恢复图标可以设置于显示界面。用户可以通过点击该恢复图标将处于放大或缩小状态的平均模板波形直接恢复到原始显示大小。可选地，还可以在再次检测到用户在波形选择区中对该波形略缩图的选择信号时，将处于放大或缩小状态的心电波形的平均模板波形直接恢复到原始显示大小。其中，原始显示大小为初始点击该波形略缩图时显示的波形的大小。
上述预设操作可以通过触屏操作、光标控制操作、语音控制操作等方式实现。其中，触屏操作即是对显示屏进行触摸操作，例如单指触摸显示屏上的预设图标、显示界面上的平均模板波形，或双指触摸显示屏并且双指在显示屏上进行远离或靠近移动等。光标控制操作可以是通过键盘、遥控杆、鼠标中的一种或多种方式实现。例如，可以设置键盘上的某两个按键分别作为放大和缩小平均模板波形的按键，当点击缩小按键时，将平均模板波形缩小显示，当点击放大按键时，将平均模板波形放大显示。同理，也可以在遥控杆上设置放大和缩小按键，对平均模板波形进行缩放显示。另外，可以通过鼠标选中平均模板波形，单击或双击鼠标右键，将平均模板波形进行缩小或放大显示，具体实施方式此处不再赘述。语音控制操作可以是检测语音数据中的关键词，并基于关键词执行相关的缩放控制指令，例如是当检测到关键词“放大”时，将平均模板进行放大显示，当检测到关键词“缩小”时，将平均模板进行缩小显示。
在此实施例中，通过响应于用户对显示界面进行的预设操作，对显示界面上显示的平均模板波形进行相应缩放处理，便于用户对平均模板波形进行查看，其中，通过检测用户预设操作的方式可以快速对波形进行缩放处理，且操作方式简单。
请参阅图6a至图7，图6a示出了本申请心电波形的数据测量方法第三实施例的流程示 意图，图6b示出了本申请心电波形的数据测量方法第四实施例的部分流程示意图，图7示出了本申请心电分析结果的显示界面示意图。本实施例的方法可以包括以下步骤：
步骤S301：心电图机显示心电波形对应的平均模板波形，并在平均模板波形的相应位置显示至少一条基准线。
其中，心电图机显示心电波形对应的平均模板波形以及如何得到平均模板波形可参阅上述实施例步骤S101、S102，在此不做赘述。
具体地，心电图机显示心电波形对应的平均模板波形，并在平均模板波形的相应位置显示至少一条基准线。其中，至少一条基准线包括P基准线、Q基准线、S基准线和T基准线中的至少一者。P基准线进一步包括P1基准线和P2基准线。T基准线进一步包括T1基准线和T2基准线。其中，基准线可以在通过预设算法进行分析后自动显示在平均模板波形的相应位置处。
步骤S302：响应于用户对基准线的移动操作，移动基准线在平均模板波形上的位置。
由于心电图机是根据基准线在平均模板波形上的位置得到对应测量值进而基于测量值进行心电分析。故基准线的位置是否准确是后续心电数据测量以及分析的关键。单靠心电图机默认确定的位置可能存在不准确的情况，故本实施例提出显示的基准线能够根据用户操作进行移动，进而可实现由用户来校准基准线位置，以保证后续心电数据测量以及分析的准确性。
具体地，不同区域内特征点处的基准线的移动范围可如下：
P1基准线：P波起点基准线，调整范围为QRS波起点至P波终点之间。
P2基准线：P波终点基准线，范围为P波起点至Q基准线之间。
Q基准线：范围为P波终点至S点基准线之间。
S基准线：范围为Q基准线至T波终点基准线之间。
T1基准线：T波起点基准线，范围为S基准线至QRS波形终点之间。
T2基准线：T波终点基准线，范围为T波起点至QRS波形终点之间。
响应于用户对基准线的移动操作，按照用户的移动轨迹，移动基准线在平均模板波形上的位置。可选地，心电图机包括触摸显示屏，该显示界面为触摸显示屏的显示界面。具体地，可以是用户触摸某一基准线，且随着触摸点在显示界面上的移动轨迹，移动基准线在平均模板波形上的位置。在其他实施例中，可采用语音控制基准线的移动，例如心电图机可以检测到用户点击显示界面上的移动图标，然后获取用户输入(如在显示界面输入或语音输入)的基准线的目标位置信息，或可以直接通过语音输入移动指令，控制基准线的移动，将该基准线移动到目标位置上。
可选地，用户可以同时选取多条基准线，响应于用户对基准线的移动操作，同时移动多条基准线在平均模板波形上的位置。通过该方式，可以避免移动某一基准线而改变多条基准线之间的间距，且可以简化用户操作，提高基准线重定位效率。
可选地，用户可以分别移动多条基准线，例如用户在移动P基准线到达目标位置之后还可以进一步移动Q基准线、S基准线或T基准线。
步骤S303：基于移动后的基准线对平均模板波形进行数据测量，得到心电波形的至少一个特征参数值。
本实施例中的心电图机可以基于基准线在平均模板波形上的位置自动计算出对应的特征参数值。
具体如，基于移动后的P基准线在平均模板波形上的位置，可以获得对应心电波形的PR间期。基于移动后的Q基准线在平均模板波形上的位置，可以获得对应心电波形的PR间期、QRS时限、QT间期、QTc间期中的至少一个。基于移动后的S基准线在平均模板波形上的位置，可以获得对应心电波形的QRS时限。基于移动后的T基准线在平均模板波形上的位置，可以获得对应心电波形的QT间期和/或QTc间期。
其中，PR间期、QRS时限、QT间期、QTc间期都是心电波形的特征参数值，也是医 生进行临床诊断的重要依据。当医生认为某一基准线所处位置不准确时，可以通过移动该基准线，对该基准线的位置进行调整，以得到正确的特征参数值。
本实施例，通过心电图机显示心电波形对应的平均模板波形，并在平均模板波形的相应位置显示至少一条基准线，通过用户对基准线的移动操作，移动基准线在平均模板波形上的位置，其中，用户可以根据实际情况对基准线位置进行调整，操作简单，基于移动后的基准线对平均模板波形进行数据测量和校准，得到心电波形的至少一个特征参数值，以使得该特征参数值更加接近于正确的特征参数值。
如图6b所示，在其他实施例中，步骤S303之后还可包括：
步骤S304：显示心电波形的至少一个特征参数值。
其中，如图2所示，可以在显示界面的参数显示区203显示至少一个特征参数值，还可以在显示界面的波形显示区201显示至少一个特征参数值。参数显示区203可以根据实际情况进行设定。响应于用户对基准线的移动操作，可以实时获取基准线在平均模板波形上的位置，并基于该位置，实时显示得到的心电波形的至少一个特征参数值，即特征参数值跟随基准线的移动而对应变化。
例如，可以在显示界面的参数显示区203显示PR间期、QRS时限、QT间期、QTc间期等特征参数值，还可以在显示界面的波形显示区201显示时限(T)，幅值(V)，和心率(bpm)等特征参数值。如果显示界面显示的特征参数值不在对应的正常特征参数范围内时，可以将该特征参数值进行标记。比如，成年人60-100次心率时，QT间期的正常值范围为0.44s～0.36s，若显示界面显示的某成年人的平均模板波形的QT间期为0.56s，不在正常值范围内，则将该特征参数值进行标红显示，以提醒用户该特征参数值不在正常值范围内。
步骤S305：检测到用户对显示界面上的分析图标的触发信号，对特征参数值进行分析，得到初始心电分析结果。
具体地，对基准线进行重定位后，当检测到用户点击显示界面上的分析图标时，心电图机可以自动对特征参数值进行分析，得到初始心电分析结果。可选地，如图7所示，初始心电分析结果可以在其他显示界面进行显示。
步骤S306：检测到用户对显示界面上的结果修改图标的触发信号，显示包含初始心电分析结果的修改输入区。
步骤S307：根据用户在修改输入区中的输入信息，更新修改输入区中的内容。
步骤S308：检测到用户对显示界面上的确认修改图标的触发信号，获取修改输入区中的当前内容，并将当前内容作为最终心电分析结果。
其中，用户可以根据显示界面中显示的平均模板波形、基准线以及对应得到的特征参数值对心电图机自动生成的初始心电分析结果的正确性进行判断。当用户认为心电图机自动生成的初始心电分析结果不正确时，可以直接在心电图机上对初始心电分析结果进行修改，以得到正确的心电分析结果。可选地，心电图机可以对初始心电分析结果和用户修改的心电分析结果进行存储，以供后续需要进行查验、调取或修改。进一步地，心电图机还可以按照一定顺序存储修改人、修改时间、修改地点等信息，以方便后续进行查验、调取或修改。
在将当前内容作为最终心电分析结果之前，还包括：在显示界面上显示签名输入区；获取用户在签名输入区中的触摸点移动痕迹，作为待验证签名；获取当前登录账户的预存签名与待验证签名是否匹配；若匹配，则将当前内容作为最终心电分析结果；若不匹配，则不将当前内容作为最终心电分析结果。
可选地，在待验证签名与当前登录账户的预存签名不匹配时，可以向当前登录账户的用户发送提示信息，以提示用户该心电图机上有异常修改心电分析结果的情况出现，当待验证签名与当前登录账户的预存签名多次不匹配时，可以将签名输入区进行锁定，以防止他人通过不断更换待验证签名，从而获得当前登录账户的预存签名，进而修改心电分析结果。例如，心电图机可以通过短信、电话或用户随身携带的心电图机配套设备的提示音对当前登录账户的用户进行提醒。此外，由于当前登录账户的用户生成待验证签名与预存签名的时间不同或 其他原因，待验证签名与预存签名会存在差异，所以即便待验证签名为当前登录账户的用户的签名也可能存在与预存签名不匹配的情况。所以为解决当前登录账户的用户的待验证签名与预存签名不匹配，从而无法修改最终心电分析结果的情况，心电图机上还可以包括摄像头模组，在当前登录账户的预存签名与待验证签名不匹配时，心电图机自动启动摄像头模组，获取当前修改心电分析结果的用户的特征信息，并将当前修改心电分析结果的用户的特征信息与当前登录账户的预存特征信息进行匹配，若匹配成功，则将当前内容作为最终心电分析结果；若匹配不成功，则不将当前内容作为最终心电分析结果，进一步地，可以将获取到的当前修改心电分析结果的用户的特征信息发送给当前登录账户的用户，并保存在心电图机中，以待后期查验。该特征信息可以是人脸图像信息或虹膜信息。通过上述方式，可以避免非当前登录账户的用户对最终心电分析结果进行篡改。
可以理解的是，显示心电波形的至少一个特征参数值的步骤与得到心电分析结果的步骤之间并无一定的先后关系，可以根据实际情况进行选择。
请参阅图8，图8示出了本申请心电波形的数据测量方法第五实施例的流程示意图。
步骤S401：心电图机显示心电波形对应的平均模板波形，并在平均模板波形的相应位置显示至少一条基准线。
其中，心电图机显示心电波形对应的平均模板波形以及如何得到平均模板波形，可参阅上述实施例步骤S101、S102，在平均模板波形的相应位置显示至少一条基准线，可参阅上述实施例步骤S301，在此不做赘述。
步骤S402：响应于用户对平均模板波形的第一预设操作，将平均模板波形放大显示，并将基准线相应显示在放大后的平均模板波形的对应位置上。
心电图机可以包括触摸显示屏，可响应用户对触摸显示屏的显示界面的操作，而对平均模板波形进行放大。具体地，第一预设操作可以包括点击显示界面上的预设图标或单击显示界面上显示的平均模板波形、触摸显示界面以在显示界面上形成两个进行远离的触摸点。
具体地，当第一预设操作为点击显示界面上的预设图标或单击显示界面上显示的平均模板波形时，响应于用户对平均模板波形的第一预设操作，将平均模板波形放大显示，可以包括：若检测到预设图标或平均模板波形被点击，则按照预设单位放大倍数将平均模板波形进行放大显示。预设图标可以设置于心电图机或与心电图机连接的其他设备的显示界面，例如，预设图标设置于心电图机的显示界面。预设单位放大倍数可以根据实际需要进行设定，预设单位放大倍数例如但不限为是1倍、3倍、10倍等。在一个应用场景中，用户点击预设图标，当心电图机检测到预设图标被点击，按照预设的3倍放大倍数将平均模板波形进行放大显示，当再次检测到预设图标被点击，则继续按照预设的3倍放大倍数将已经放大3倍的平均模板波形进一步进行放大显示，此时显示界面显示的平均模板波形为原始平均模板波形的9倍大小。可以理解的是，波形的放大可以是在一定预设范围内。当响应于用户一次或多次点击显示界面上的预设图标或一次或多次单击显示界面上显示的平均模板波形，将显示界面上显示的平均模板波形进行放大至放大阈值后，继续检测到点击显示界面上的预设图标或单击显示界面上显示的平均模板波形，可以不再对显示界面上显示的平均模板波形进行放大，或者将显示界面上显示的平均模板波形恢复至原来大小。
当第一预设操作为双击显示界面上显示的平均模板波形时，响应于用户对平均模板波形的第一预设操作，将平均模板波形放大显示，可以包括：获取两次点击平均模板波形之间的时间差；基于时间差，确定放大倍数；按照放大倍数将平均模板波形进行放大显示。可选地，时间差越大对应的放大倍数就越小。其中，基于时间差确定放大倍数之前，还包括建立时间差与放大倍数或时间差范围与放大倍数或的对应关系。例如，时间差为0.1s、0.5s、1s，分别对应的放大倍数为10倍、5倍、1倍。若检测到两次点击平均模板波形之间的时间差为0.5s，对应将平均模板波形放大5倍。又例如，时间差范围为100ms～0.1s、0.1s～0.5s、0.5s～1s，分别对应的放大倍数为8倍、4倍、2倍，其中每个时间差范围不包括该范围的右端点值。若检测到两次点击平均模板波形之间的时间差为0.5s，0.5s属于时间差范围0.5s～1s，则对应将平 均模板波形放大2倍。可以理解的是，波形的放大可以是在一定预设范围内。当响应于用户一次或多次双击显示界面上显示的平均模板波形，将显示界面上显示的平均模板波形进行放大至放大阈值后，继续检测到双击显示界面上显示的平均模板波形，可以不再对显示界面上显示的平均模板波形进行放大，或者将显示界面上显示的平均模板波形恢复至原来大小。
当第一预设操作为触摸显示界面以在显示界面上形成两个进行远离的触摸点时，响应于用户对平均模板波形的第一预设操作，将平均模板波形放大显示，可以包括：获取两个触摸点进行远离时的速度和/或停止远离时的距离；基于速度和/或距离，确定放大倍数；按照放大倍数将平均模板波形进行放大显示。心电图机可以获取两个触摸点远离时的速度和停止远离时的距离。可选地，速度越快和/或距离越大对应的放大倍数就越大。其中，基于速度和/或距离确定放大倍数之前，还包括建立速度与放大倍数的对应关系、距离与放大倍数的对应关系。具体地，可根据需要预先建立对应关系包括：速度是10cm/s、1cm/s、1mm/s，对应的放大倍数为9倍、6倍、3倍；距离是0.1cm、1cm、2cm，对应的放大倍数为1倍、2倍、3倍。例如，只根据速度来确定放大倍数，则基于上述速度的对应关系，当确定当两个触摸点进行远离时的速度为1cm/s，得到对应的放大倍数为6倍。又例如，只根据距离来确定放大倍数，则基于上述距离的对应关系，当确定当两个触摸点停止远离时之间的距离为2cm，得到对应的放大倍数为3倍。再例如，可知根据速度和距离来确定放大倍数，则基于上述速度和距离的对应关系，当两个触摸点以1cm/s的速度进行远离，停止远离时两个触摸点之间的距离为1cm，对应的放大倍数为6*2＝12倍。
可选地，如图5所示，放大显示平均模板波形的波形显示区可以占据整个显示界面，以通过整个波形显示区显示放大后的平均模板的波形，从而便于用户查看平均模板波形或对平均模板波形进行其他操作。此时，显示界面上可以设置测量尺图标。用户点击测量尺图标，将测量尺显示在平均模板波形的相应位置，以对在放大后的平均模板波形进行测量，得到特征参数值。例如，特征参数值可以是时限、幅值、心率等。
在一些实施例中，心电图机还可以包括恢复图标。该恢复图标可以设置于显示界面。用户可以通过点击该恢复图标将处于放大状态的平均模板波形直接恢复到原始显示大小。可选地，还可以在再次检测到用户在波形选择区中对该波形略缩图的选择信号时，将处于放大状态的心电波形的平均模板波形直接恢复到原始显示大小。其中，原始显示大小为初始点击该波形略缩图时显示的波形的大小。
上述预设操作可以通过触屏操作、光标控制操作、语音控制操作等方式实现。具体实现方式可参考上面实施例的相关描述，在此不做赘述。
心电图机在将平均模板波形放大显示时，还可以将基准线相应显示在放大后的平均模板波形的对应位置上。例如，可获得基准线在放大前的平均模板波形上的原始位置信息，并将原始位置信息与平均模板波形的当前放大倍数的乘积作为基准线在放大后的平均模板波形上的最新位置，并将该基准线显示在该最新位置上。
可以理解的是，本文所述的将平均模板波形放大显示的实施例中，由于波形放大后在原来的波形显示区可能无法显示放大后的完整波形，故可在波形显示区显示部分放大后的波段，在检测到用户对显示波形的滑动操作，例如向右滑动的操作，则在波形显示区上显示位于之前显示的放大后波段右侧的波段，若向左滑动的操作，则在波形显示区上显示位于之前显示的放大波段左侧的波段。或者，可不局限只在波形显示区显示放大后的波段，而是在完整显示界面上显示放大后的波形(如图5所示)。
步骤S403：响应于用户对基准线的第二预设操作，调整基准线在放大后的平均模板波形的位置。
第二预设操可以为上述实施例中的移动操作，或者为用户对显示界面的移动图标的点击操作、或者用户进行语音控制等，例如心电图机检测到用户点击显示界面上的移动图标，获取用户输入(如在显示界面输入或语音输入)的基准线的目标位置信息，则将该基准线移动到目标位置上。
例如，按照用户的移动轨迹，移动基准线在放大后的平均模板波形上的位置。其中，通过将波形进行放大，在放大后的平均模板波形上移动基准线可以快速、精确的移动基准线到目标位置。在其他实施方式中，可以在检测到用户对基准线的第二预设操作时，自动放大平均模板的波形，用户根据放大后的平均模板的波形调整基准线在放大后的平均模板波形的位置。通过上述方式，可以在移动基准线的同时对平均模板波形进行放大，过程快捷，且不需要用户手动对波形进行放大。
可选地，在调整基准线在放大后的平均模板波形的位置后，还可根据用户的选择确定是否锁定当前显示界面，在锁定当前显示界面后用户再次触摸当前显示界面不会对该显示界面内容进行更改。此外，用户还可以根据需要解锁当前显示界面。上述步骤可以通过用户设置的快捷键来实现，快捷键可以设置于显示界面上。
步骤S404：基于调整后的基准线对平均模板波形进行数据测量，得到心电波形的至少一个特征参数值。
其中，对于该步骤的描述可以参考上述实施例步骤S303中相应位置的描述。当然，在其他实施例中，步骤S404之后还可以包括上述实施例步骤S304-S308的步骤，此处不做赘述。
在本实施例中，心电图机可以显示心电波形对应的平均模板波形，并在平均模板波形的相应位置显示至少一条基准线，通过第一预设操作将平均模板波形放大显示，并将基准线相应显示在放大后的平均模板波形的对应位置上，然后通过第二预设操作，调整基准线在放大后的平均模板波形的位置，其中，由于将平均模板的波形进行放大显示，便于用户找到基准线调整的目标位置，进而基于调整后的基准线对平均模板波形的相关参数进行准确测量，得到心电波形的至少一个特征参数值，以使得该特征参数值更加接近于正确的该特征参数值。
请参阅图9至图10b，图9示出了本申请心电波形的数据测量方法第六实施例的流程示意图，图10a示出了本申请第Ⅱ导联的平均模板波形放大后的显示界面的另一示意图，图10b示出了本申请第Ⅱ导联的平均模板波形放大后的显示界面的又一示意图。
步骤S501：心电图机显示心电波形对应的平均模板波形，并在平均模板波形的相应位置显示至少一条基准线。
其中，心电图机显示心电波形对应的平均模板波形以及如何得到平均模板波形，可参阅上述实施例步骤S101、S102，在平均模板波形的相应位置显示至少一条基准线，可参阅上述实施例步骤S301，在此不做赘述。
步骤S502：基于预设区域信息或用户选择的区域信息，确定显示界面上的待放大区域。
本实施例中，显示界面上的待放大区域可默认设置或用户进行设置。该待放大区域用于选择出后续放大显示的波形，即，不在待放大区域中的波形则不会进行后续放大显示。故本实施例中，显示界面上显示的平均模板波形可根据待放大区域的设置而实现部分放大。
具体地，预设区域信息可以是预先设定的显示界面中的某一区域的位置信息。用户选择的区域信息可以包括用户在显示界面上选中的区域的位置信息或用户输入的位置信息。预设区域信息或用户选择的区域信息可以是整个波形显示区，或者部分波形显示区。待放大区域确定后，心电图机仅会对待放大区域内显示的平均模板波形进行放大显示。
步骤S503：响应于用户对平均模板波形的第一预设操作，获取位于待放大区域中的平均模板波形作为待放大波形。
本实施例步骤S503、S504、S505和S506可用于实现响应于用户对平均模板波形的第一预设操作，将平均模板波形放大显示，并将基准线相应显示在放大后的平均模板波形的对应位置上的步骤。
其中，对于第一预设操作的阐述请参见上述步骤S402中相应位置的阐述。例如，继续参阅图2，用户仅需要对T1-T2段波形进行放大显示，那么用户可以在显示界面上选中T1-T2段波形所在的区域作为待放大区域204，从而在用户对平均模板波形进行第一预设操作(如点击平均模板波形)时，可以获取待放大区域204中的T1-T2段波形以作为待放大波形。
步骤S504：对待放大波形的至少部分波段进行放大显示。
在确定得到待放大波形后，可对待放大波形的至少部分波段进行放大显示。其中，放大后的波段可在显示界面的波形显示区中进行显示，如图10a所示，在获得待放大区域204中的T1-T2段波形作为待放大波形后，可在波形显示区域202上显示放大后的T1-T2段波形。当然，放大后的波段也可以只在上述待放大区域204中进行显示，例如，可将T1-T2段波形的至少部分波段放大后显示在待放大区域204中。又或者，放大后的波段还可以在完整显示界面上进行显示，如图10b所示，若用户选择波形显示区域中P1-T2段波形所在的区域作为待放大区域，可将该P1-T2段波形进行放大显示。
可以理解的是，当放大倍数较大时，待放大波形不能全部显示在显示界面中，考虑到放大后的波形未必能完整显示，可考虑选择待放大波形的部分波段进行放大显示。具体地，可选择待放大波形中用户预先选中的基准线所在的波段进行放大显示，或者可选择待放大波形的中间波段进行放大显示，具体波段选择方式可根据实际需求进行设定，在此不做限制。需要说明的是，用户预先选中的基准线为待放大波形中的基准线。
本实施例以选择待放大波形中用户预先选中的基准线所在的波段进行放大显示为例进行具体说明。在一实施例中，可在本步骤S501之前，还包括响应于用户对至少一条基准线的选中操作，确定所述至少一条基准线为第一目标基准线；本步骤S504对应具体包括：将待放大波形中包含第一目标基准线的波段进行放大显示。一种情况：响应于用户选取一条基准线的选中操作，将该条基准线作为第一目标基准线，将待放大波形中包含第一目标基准线的波段进行放大显示，其中包含第一目标基准线的波段可以是包含第一目标基准线的预设时间范围内的波段。例如，响应于用户对S基准线的选中操作，将S基准线作为第一目标基准线，将包含S基准线的10ms范围内的波段进行放大显示。另一种情况是：响应于用户选取至少两条基准线的选中操作，将该至少两条基准线作为第一目标基准线，将待放大波形中包含第一目标基准线的波段进行放大显示，其中包含第一目标基准线的波段可以是首尾两条基准线之间的波段或包含首尾两条基准线的预设时间范围内的波段。其中，预设时间范围可以根据实际情况进行选取。例如，响应于用户对P1基准线、Q基准线和S基准线的选中操作，将P1基准线、Q基准线和S基准线作为第一目标基准线，P1基准线和S基准线分别为首尾基准线，将P1基准线和S基准线之间的波段或包含P1基准线和S基准线的20ms内的波段，进行放大显示。其中，选中操作可以通过触屏、光标或语音输入等方式实现。例如，通过触摸Q基准线，将Q基准线选中。通过确定第一目标基准线，并将包含第一目标基准线的波段进行放大显示，即可以通过选中的基准线确定当前要显示的放大波段，从而在后续操作中能够针对性地对第一目标基准线进行移动，而不需要在显示放大波形后，再去查找需要进行重定位的基准线，可以简化用户操作。
步骤S505：将基准线相应显示在放大后的平均模板波形的对应位置上。
其中，心电图机可以获取基准线在放大前的待放大波形上的原始位置，确定原始位置在放大后的待放大波形上的对应位置，并将基准线显示在对应位置上。例如，S基准线在放大前的待放大波形上的5ms位置，在将待放大波形进行放大2倍显示后，S基准线的原始位置也同样被放大两倍，从而可以确定S基准线在放大后的待放大波形上的对应位置为10ms位置，并将基准线显示在10ms位置上。
在一情况下，由于用户需要移动的基准线当前所在位置与目标位置偏离较远，当用户以目标位置确定待放大区域，将待放大区域进行放大显示后，由于该需要移动的基准线偏离较远，从而无法在放大后的当前显示界面进行显示，需要移动待放大区域才能将该基准线进行选中，然后再移动该基准线和待放大区域到目标位置。所以本实施例，在步骤S501之前还可以包括：响应于用户对至少一条基准线的选中操作，确定至少一条基准线为第二目标基准线。对应地，将基准线相应显示在放大后的平均模板波形的对应位置上包括：将第二目标基准线显示在当前显示的放大后的平均模板波形的第二预设位置上。其中，第二预设位置可以是正中间位置或任一个位置。当第二目标基准线仅包括一条基准线时，可以直接将该基准线显示在预设位置上。当第二目标基准线包括多条基准线时，可以将多条基准线分别显示在不同的 预设位置上或将多条基准线在某一预设位置上按一定间隔排列显示。在当前显示的放大波段上可始终显示第二目标基准线。举例说明，如图2所示，用户需要移动Q基准线到待放大区域204中，但是由于Q基准线距离待放大区域较远，从而无法在放大后的当前显示界面进行显示(如图10a所示)，但是可以在进行第一预设操作前，将Q基准线选中，当用户进行第一预设操作将待放大区域中的波段进行放大显示后，Q基准线可以直接显示在该放大波段的正中间位置或任一个位置，以便于用户对Q基准线进行后续操作。
步骤S506：在显示界面的第一预设位置上显示包含完整的平均模板波形的波形缩小图，且在波形缩小图中的相应位置显示对应待放大区域的区域框。
在步骤S504对待放大波形的至少部分波段进行放大显示之后，为了便于用户重新定位新的待放大区域，可在显示界面的第一预设位置显示包含完整的平均模板波形的波形缩小图。
第一预设位置可以根据需要进行设定，例如第一预设位置可以右上角、左上角、右下角或左下角等。
如图10b所示，在显示界面的左上角位置上显示包含完整的平均模板波形的波形缩小图901，且在波形缩小图901中的相应位置显示对应待放大区域的区域框902。
如图2所示，波形缩小图还可以是波形选择区201中的波形略缩图，在波形略缩图中的相应位置显示对应待放大区域的区域框903，此处不在赘述。
步骤S507：检测到用户对波形缩小图中区域框的移动操作，并基于移动后区域框在波形缩小图中的位置，更新待放大区域的位置。
其中，移动操作可以是按住区域框，并在波形缩小图中拖动区域框，即移动区域框在波形缩小图中的位置。或者，显示界面进一步包括滑块区，移动操作可以是拖动滑块区中的滑块，在检测到滑块区中的滑块被拖动时，对应移动区域框在波形缩小图中的位置。可以理解的是，上述区域框所框住的区域即为待放大区域。
具体地，检测到用户按住区域框，并在波形缩小图中拖动区域框或拖动滑块区中的滑块，基于移动后区域框在波形缩小图中的位置，更新待放大区域的位置。
步骤S508：获取更新后的待放大区域中的平均模板波形作为新的待放大波形，并重新执行对待放大波形的至少部分波段进行放大显示以及后续步骤。
具体地，将更新后的待放大区域中的平均模板波的至少部分波段进行放大显示，并将基准线相应显示在放大后的平均模板波形的对应位置上。其中，上述步骤的具体执行可参考上述说明。
在一个应用场景中，当待放大区域中显示的部分平均模板波形不包括当前用户需要调整的波段时，可以通过移动波形缩小图中的区域框，快速找到需要调整的波段。当然，也可以通过触摸显示界面生成触摸点，根据触摸点的移动轨迹对应移动平均模板波形，以调整显示界面中显示的平均模板波形。例如，当前显示界面中显示的平均模板波形为P2-Q段波形，当触摸点向左滑动时，对应将平均模板波形向左滑动，从而显示QS段波形。
步骤S509：响应于用户对基准线的第二预设操作，调整基准线在放大后的平均模板波形的位置。
步骤S510：基于调整后的基准线对平均模板波形进行数据测量，得到心电波形的至少一个特征参数值。
其中，对于步骤S509和S510的描述可以分别参考上述实施例步骤S403和步骤S303中相应位置的描述。当然，在其他实施例中，步骤S510之后还可以包括上述实施例步骤S304-S308的步骤，此处不做赘述。
在本实施例中，通过设置待放大区域，且仅将待放大区域内的平均模板波形进行放大，可以提高对平均模板波形进行放大显示的灵活性，而且由于可以仅对需要调整的波段进行放大显示，可以提高基准线定位的准确性；其次，由选中的基准线可以快速确定当前要显示的放大波段；再次，在将待放大区域中的待放大波形进行放大显示之后，可以通过改变波形缩小图中区域框的位置来改变待放大区域的位置，从而能够快速、准确地更新待放大区域内的 待放大波形，并将待放大波形进行放大显示。

壳体11包括相背设置的第一侧部111和第二侧部112，第一侧部111用于与外设装置连接，在一个实施场景中，外设装置可以包括把手20、打印组件30中的任意一种。在一个具体的实施场景中，外设装置与第一侧部111连接时，第二侧部112与外设装置同时抵接于支撑面，从而使得显示屏12所在的平面与支撑面之间形成预定角度，从而便于用户查看显示屏12上所显示的界面，或者触摸显示屏12，预定角度可以设置为30度、35度等等，本实施例在此不做具体限制。
此外，为了方便、快捷地实现主机10与外设装置之间的连接，还可以在主机10和外设装置上设置相互匹配的连接件。以外设装置包括把手20为例，主机10靠近于第一侧部111的两侧均开设有定位槽113，把手20包括两个相对设置的第一定位臂21，第一定位臂21与定位槽113相互匹配，从而可以将第一定位臂21插入定位槽113，实现主机10与把手20之间的可拆卸连接。在一个实施场景中，第一侧部111还可以开设有若干卡接孔(图未示)，把手20还包括设置于两个第一定位臂21之间的第一安装部22，第一安装部22上设置有与卡接孔相互匹配的第一卡接柱221。在一个实施场景中，为了便于用户通过把手20携带主机10，把手20还包括提手23，提手23、两个第一定位臂21以及第一安装部22围合形成穿过槽24，以供用户握持，进而用户可以方便地携带主机10。或者，当外设装置包括打印组件30时，与把手20类似地，打印组件30可以包括两个相对设置的第二定位臂31，第二定位臂31与定位槽113相互匹配，从而可以将第二定位臂31插入定位槽113，实现主机10与打印组件30之间的可拆卸连接。在一个实施场景中，打印组件30还包括设置于两个第二定位臂31之间的第二安装部32，第二安装部32上设置有与卡接孔相互匹配的第二卡接柱321。
