1.结构特点
(1)便携式单导心电记录仪由主机端、电池端和连接线组成，简称两端型。
(2)采用一体化的设计方案，将电路部分与电极扣完美融合在一起，极大的方便的用户的使用和操作。
(3)主机与电池之间的连接器使用硅胶为原材料，充分考虑了人体表面肌肉的弧度，硅胶的柔软性使仪器粘贴在各种人体表面时，都能进行充分的接触，确保心电信号的稳定。
(4)主机中主要由低功耗MCU、心电数据采集芯片、蓝牙或wifi或射频模块或无线数传模块等其它无线传输模块组成，通过精密的结构设计和PCB设计，在极小的尺寸和空间里，实现了心电信号采集和传输功能。
(5)电池端采用可充电电池为整个系统供电，利用触电点式设计，使用专用充电器进行充电。
(6)两种规格长度可以监测V1～V6导联心电图。
2.技术特点
(1)心律失常检出率高；
通过与医用动态心电监测仪(24小时Holter)进行对比试验，两端型便携式单导心电记录仪的心律失常检出率明显高于Holter。
通过佩戴两端型便携式单导心电记录仪14天对200名患者进行了试验，两端型便携式单导心电记录仪检测出186位心律失常患者，检出率为93.00％；而佩戴24小时Holter检测出125位，检出率62.50％。
(2)抗干扰能力强；
在两端型便携式单导心电记录仪的研发过程中，我公司的最初设计的设备如附图9所示(简称中间型)，电子元器件全部放在中间位置，两边只有电极扣。
在试验时发现由于该结构的所有电子元器件的集中设计，导致设备中间部分太重，无法避免剧烈运动时的干扰。从两种设备描记的心电图可以看出，佩戴中间型在剧烈运动状态下(心率122次/分)明显出现干扰，基线振荡太大，无法判断心电图各个波形(P波、QRS波、T波)的时间及振幅(附图10)；
佩戴两端型在剧烈运动状态下(心率122次/分)的基线平稳，干扰少，可以测量各个波形时间、振幅，如PR间期0.16秒，P波高度0.12毫伏，QRS波间期0.10秒等(如附图11)；而且，佩戴两端型在非剧烈运动状态下，也能够准确测量心电图的各个波形时间、振幅，同时非剧烈运动下的测量效果依然明显优于中间型。
(3)可以发现局部心肌供血不足；
通过一项为检测可疑冠心病(心绞痛、心肌梗死)而接受心电图监测的256名患者研究表明，佩戴两端型的便携式单导心电记录仪14天，检测出异常Q波和ST-T改变233名患者，检出率为91.02％，均反映急性或者慢性心肌供血不足，而采用中间型进行测量得到的检出率会降低20％、甚至30％以上。
检测出的233名病例中，ST段下移115名，占总病例的49.36％；异常Q波48名，占总病例的20.60％；ST段抬高43名，占总病例的18.45％，T波倒置或者低平27名，占总病例的11.59％。
3.对比试验
(1)一致性试验
将两端型或中间型便携式单导心电记录仪一端粘贴在左锁骨下，另一端分别粘贴在附图12所示的V1～V6(第一电极片V1贴于胸骨右端第四肋间；第二电机片V2贴于胸骨左端第四肋间；第三电极片V3贴于第二电机片V2和第四电极片V4中间的第五肋间(平行乳头部位)；第四电极片V4贴于左锁骨中线第五肋间(乳头正下方乳沟处)；第五电极片V5贴于左腋前线上与第四电极片V4同一水平线上；第六电极片V6贴于左腋中线上与第四电极片V4同一水平位置)处，可以监测6个导联的心电图。
在医院针对200名正常人，使用本发明两端型、中间型和医用12道心电图机(GE MAC1200ST)进行V1、V2、V3、V4、V5、V6心电图测量的实验结果表明：两端型与医用12道心电图机(GE MAC1200ST)相比，两者结果的一致性最高为0.99851(图14)，最低为0.99052(图15)；中间型与医用12道心电图机(GE MAC1200ST)相比，两者结果的一致性最高为0.86065(图16)，最低为0.69325。由此说明，针对正常心电图的监测，本发明两端型的性能明显优于中间型。
在医院针对200名心脏病患者，使用本发明两端型、中间型和医用12道心电图机(GE MAC1200ST)进行V1、V2、V3、V4、V5、V6心电图测量的实验结果表明：两端型与医用12道心电图机(GE MAC1200ST)相比，两者结果的一致性最高为0.99802(图17)，最低为0.90865(图18)；中间型与医用12道心电图机(GE MAC1200ST)相比，两者结果的一致性最高为0.81256(图19)，最低为0.67932。由此说明，针对异常心电图的监测，本发明两端型的性能明显优于中间型。
(2)有效长度试验
左锁骨下到V1～V6的距离不等，所以有两种长度(两个电极扣中心的间距)规格的两端型或中间型便携式单导心电记录仪与之对应。经过试验，得出了两种规格的有效长度范围和最佳长度范围。

4.改善方案
两端型便携式单导心电记录仪的进一步改进方案是拉伸型，如图8所示。电子元器件集中放置在固定端，另一端(移动端)可以通过中间的拉伸装置进行长度扩展(50mm～300mm)。这样，一个设备就可实现6个导联(V1～V6)心电图的分别监测，在此种两端型改进为拉伸型的情况下，进行了和前述不拉伸的两端型相同的测试，基本得出了和前述不拉伸的两端型的测试结果相同的数据。
两端型便携式单导心电记录仪电路可以按照需要分别设置于固定端和/或移动端上，实验数据和前面两端型的基本相同，该技术方案可以适用上述拉伸型的两端型和不拉伸的两端型的所有实施例。
中间型便携式单导心电记录仪的进一步改进方案也可以是拉伸型，电子元器件集中放置在中间，一端的电极片为固定端，另一端的电极片(移动端)可以通过中间的拉伸装置进行长度扩展(50mm～300mm)。这样，一个设备就可实现6个导联(V1～V6)心电图的分别监测。但是中间型改进为拉伸型的测量效果、及精确度与两端型改进为拉伸型的测量效果及精确度对比会降低20％～30％以上。
(1)一致性试验
将中间型便携式单导心电记录仪的改进方案拉伸型一端粘贴在左锁骨下，另一端分别粘贴在附图12所示的V1～V6(第一电极片V1贴于胸骨右端第四肋间；第二电机片V2贴于胸骨左端第四肋间；第三电极片V3贴于第二电机片V2和第四电极片V4中间的第五肋间(平行乳头部位)；第四电极片V4贴于左锁骨中线第五肋间(乳头正下方乳沟处)；第五电极片V5贴于左腋前线上与第四电极片V4同一水平线上；第六电极片V6贴于左腋中线上与第四电极片V4同一水平位置)处，可以监测6个导联的心电图。
