Description
一种移动终端及心电检测的方法 技术领域
本发明涉及电子技术领域， 特别涉及一种移动终端及心电检测的方法。 背景技术
由于心脏自动不断地进行有节奏的收缩和舒张活动，才使得血液在封闭的 循环系统中不停地流动， 使生命得以维持。 心脏在搏动前后， 心肌发生激动。 在激动过程中， 会产生微弱的生物电流。 这样， 心脏的每一个心动周期均伴随 着生物电变化。这种生物电变化可传达到身体表面的各个部位。 由于身体各部 分组织不同，距心脏的距离不同， 心电信号在身体不同的部位所表现出的电位 也不同。 对正常心脏来说， 这种生物电变化的方向、 频率、 强度是有规律的。 若通过电极将体表不同部位的电信号检测出来，再用放大器加以放大， 并用记 录器描记下来， 就可得到心电图形。 根据所记录的心电图波形的形态、 波幅大 小以及各波之间的相对时间关系，再与正常心电图相比较，便能诊断出心脏疾 病。 诸如心电节律不齐、 心肌梗塞、 期前收缩、 高血压、 心脏异位搏动等。
目前，在医院通过心电图机对病人的心脏进行监测， 心电图机是通过在人 的躯干、 四肢等位置贴上电极， 将心脏活动时心肌激动产生的生物电信号（心 电信号）自动记录下来，其精度较高，为临床诊断和科研常用的医疗电子仪器。 其缺点在于医院设备庞大， 数量有限， 不能支持众多患者长时间的检测， 而且 一般病人还需要正常工作、 生活， 无法一直待在医院里面。 根据医学分析， 目 前有很多心脏问题都是偶发性的， 短时间的测试并不能有效的诊断出来。
另外， 为方便用户的日常使用， 出现了便携式心电检测设备， 使用者随身 携带专门的心电检测设备，将数据实时记录在存储卡中， 定期拿去医院导出数 据分析。 与方案一相比， 该方案比较便捷， 使用者可以正常工作生活， 而不用 一直待在医院。 但是， 目前常用的便携式的心电检测仪， 需要随身佩戴一个专 门的心电图记录器， 虽然比方案一在医院躺着 #文检查已经方便许多， 可还是会 给用户造成不便。将数据定期拿去医院分析对于使用者来说也不方便， 而且专 用的心电检测设备成本较高。 发明内容
