摘要

导读:减少假警报是自我保健的一个重要挑战,而在心脏病学领域,最重要的假警报原因之一是心电图记录中的电极错位,这是早期和普遍检测心血管疾病的主要调查。在这种情况下,我们提出并评估了基于Mason-Likar的3D ECG记录系统的电极反向识别的新方法,该方法特别便于在自我保健中使用,并且可以实现如先前报道的高计算机化缺血检测精度。方法:我们用数学方法模拟了LA、RA、LL和C2电极的6次成对逆转对3个ECG导联I、II和V2的影响。然后,我们的方法包括通过CAVIAR软件对新记录的3D心电图和六个衍生心电图进行串行比较,模拟电极反转与标准的12导联参考心电图。我们进一步使用评分方法来比较这些分析结果,然后应用决策树模型从ICU记录的121例患者的学习集中提取最相关的测量值。结果:通过对学习集的7组序列分析结果的比较,确定了QRS和T空间方向变化的4个测量值的复合标准,并提供了100%的反转识别精度。在90例患者的两组测试中,分别记录了PTCA球囊充气过程(模拟缺血过程)和PTCA前的2098次和2036次有代表性的ECG心跳,获得了几乎相同的结果,灵敏度为99.99%,特异性为100%。结论:心电电极电缆互换的个性化自动检测在自我护理中准确率几乎达到100%,且几乎可以实时进行。

False Alarm Reduction in Self-Care by Personalized Automatic Detection of ECG Electrode Cable Interchanges.

Introduction: False alarm reduction is an important challenge in self-care, whereas one of the most important false alarm causes in the cardiology domain is electrodes misplacements in ECG recordings, the main investigations to perform for early and pervasive detection of cardiovascular diseases. In this context, we present and assess a new method for electrode reversals identification for Mason-Likar based 3D ECG recording systems which are especially convenient to use in self-care and allow to achieve, as previously reported, high computerized ischemia detection accuracy.

Methods: We mathematically simulate the effect of the six pairwise reversals of the LA, RA, LL, and C2 electrodes on the three ECG leads I, II, and V2. Our approach then consists in performing serial comparisons of the newly recorded 3D ECG and of the six derived ECGs simulating an electrode reversal with a standard, 12-lead reference ECG by means of the CAVIAR software. We further use a scoring method to compare these analysis results and then apply a decision tree model to extract the most relevant measurements in a learning set of 121 patients recorded in ICU.

Results: The comparison of the seven sets of serial analysis results from the learning set resulted in the determination of a composite criteria involving four measurements of spatial orientation changes of QRS and T and providing a reversal identification accuracy of 100%. Almost the same results, with 99.99% of sensitivity and 100% of specificity, were obtained in two test sets from 90 patients, composed of 2098 and 2036 representative ECG beats respectively recorded during PTCA balloon inflation, a procedure which mimics ischemia, and before PTCA for control.

Conclusion: Personalized automatic detection of ECG electrode cable interchanges can reach almost the maximal accuracy of 100% in self-care, and can be performed in almost real time.

期刊介绍: The overall aim of the International Journal of Telemedicine and Applications is to bring together science and applications of medical practice and medical care at a distance as well as their supporting technologies such as, computing, communications, and networking technologies with emphasis on telemedicine techniques and telemedicine applications. It is directed at practicing engineers, academic researchers, as well as doctors, nurses, etc. Telemedicine is an information technology that enables doctors to perform medical consultations, diagnoses, and treatments, as well as medical education, away from patients. For example, doctors can remotely examine patients via remote viewing monitors and sound devices, and/or sampling physiological data using telecommunication. Telemedicine technology is applied to areas of emergency healthcare, videoconsulting, telecardiology, telepathology, teledermatology, teleophthalmology, teleoncology, telepsychiatry, teledentistry, etc. International Journal of Telemedicine and Applications will highlight the continued growth and new challenges in telemedicine, applications, and their supporting technologies, for both application development and basic research. Papers should emphasize original results or case studies relating to the theory and/or applications of telemedicine. Tutorial papers, especially those emphasizing multidisciplinary views of telemedicine, are also welcome. International Journal of Telemedicine and Applications employs a paperless, electronic submission and evaluation system to promote a rapid turnaround in the peer-review process.
