12 導程心電圖診斷暨管理的臨床作業程 序的E 化是醫療院所心臟血管科未來的趨 勢。然而，12 導程心電圖醫療資訊系統的開 發，面臨了2 個主要的障礙: (1)大多數臨床使 用的12 導程心電圖儀，未遵守醫療資訊標準 的規範，一般以自行格式，對其數位輸出訊號 檔案加密及壓縮；(2)未能將心電訊號的基本 特徵加以標示，作為輔助診斷參考之用。本研 究的主要目的是開發符合醫療資訊標準的12 導程DICOM-ECG 診斷報告暨管理資訊系 統，並符合臨床心臟醫學診療之用。我們首先 將臨床12 導程心電圖的數位檔案，相容的 SCP-ECG 心電圖檔案解碼，並萃取其診斷訊 息及原始心電訊號，上傳至資料庫並開發使用 介面作有效管理；同時以小波轉換技術，辨識 心電訊號的特徵點，提供臨床醫生作為重要的 診斷輔助參考。本研究開發的12 導程心電圖 醫療資訊系統，以DICOM-ECG 作為儲存心 電圖診斷報告格式，可增加未來院際間病歷交 換的方便性，並提供臨床心電圖診療的作業E 化。

标准心电数据交换协议SCP-ECG(StandardC ommunicationP rotocolfo rC omputerizedE lectorcardiography)定义了用 干交换的心电数据的内容和格式用于控制在不同工作站和用户间的数据流的查询和控制消息以及在数字心电图机和 ECG管理系统间的低层传输协议。文章对SCP数据结构和推荐的压缩方法进行了详细分析提出了生成符合SCP标准的 数据结构的万法并在此基础上对常用的数字心电图机的分析软件进行了改进使之完全支持SCP标准。

Electrocardiography is one of the most frequently applied non-invasive tests for early detection of heart disease, which is a leading cause of morbidity and mortality in western countries. It is estimated that more than 100 million ECGs are recorded annually in Western Europe. In view of the high costs of health care it is of eminent importance that the results of this straightforward cardiac test can be easily communicated between the various health care providers and that they can be stored in electronic patient health records to support continuity of care. It is not anymore acceptable that, in the age of information technology, millions of Euros are wasted for unnecessarily repeated tests or that patients do not obtain appropriate care because relevant clinical information is not available at the point of care.

ECG Data Interchange Formats and Protocols – Status and Outlook

Nowadays, the large-scale deployment of electronic health record systems and eHealth services has to face with a real multi-vendor environment. Even if each manufacturer supports an existing standard for communication and storage of ECG data, the large number of co-existing ECG standards is a major problem. In this direction, an online service operating as a gateway between SCP-ECG, the European standard for communication and storage of resting ECGs, and the DICOM waveform standard (Supplement 30), a common format for the communication of time series data including vital signs and ECGs, has been developed. The open availability of this service in the OpenECG portal is expected to facilitate digital ECG interoperability and contribute to the harmonization of ECG standards.
