以XML為基礎的心電圖管理系統
XML-based ECG Management System
摘要
心電圖（Electrocardiogram，ECG），是醫生用來診斷心臟疾病的最普遍方式。心電儀輸出的方式一般分為兩種，一為紙本ECG，另一為電腦化的數位檔案。紙本ECG將心電儀量測所得的心電訊號及相關資訊，列印在一張A4大小規格的紙上。這是目前最普遍的輸出與存取方式，但不利於資訊交換、資料存取及數據之研究分析。由於醫療資訊電腦化之需求，大部分的心電儀本身也具有數位化輸出的功能，但是因為商用心電儀一般採用專屬的資料格式，須有專用商業軟體才可使用，這不但增加操作成本，且不同的機型間也無法進行資料交換。基於上述理由，本研究將商用心電儀產生的數位資料轉換成XML-ECG格式以利於資訊的交換與分析。本研究與地區醫院合作，收集心電儀的SCP-ECG資料，解碼取得內含資訊及心臟各導程原始電位數據後，轉為符合HL7與FDA標準之XML格式，並開發XML-ECG之資料庫管理系統。至於ECG波形閱覽及數據分析，本研究以SVG技術開發互動式SVG-ECG，一方面提供臨床醫師熟悉的傳統ECG圖形介面；另一方面，藉由SVG的互動性，提供ECG數據比對與分析之功能。

Electrocardiogram (ECG) is the most commonly used tool for diagnosis of heart-related diseases. In general, there are two types of output forms from commercial electrocardiographs: paper ECG and computerized digital format. In paper ECG, the measured electrocardiac signal and related information are printed on a sheet of A4-size paper. Paper ECG has been widely adopted as the standard output for most of commercial electrocardiographs. However, it is unfavorable for information exchange, information management, and signal analysis. To meet the requirement of hospital information system, most of modern electrocardiographs can also output digital electronic files (e-files). Nevertheless, e-files so generated are encoded in various proprietary formats. This not only increases operation cost, but hinders information exchange among different models.Due to the reasons mentioned above, this study transformed digital data obtained form commercial electrocardiographs into the XML-ECG format so that information in ECG can be conveniently exchanging and analyzed. In this study, we worked with a regional hospital, collected SCP-ECG data from electrocardiographs, and decoded SCP-ECG file to acquire raw data of 12-lead electrocardiac signal and related annotative information. The content of decoded SCP-ECG files was then transformed into the XML format based on HL7 and FDA standards. In addition, a database system for managing the XML-ECG files was developed in this study. As for browsing and analysis of ECG waveform, SVG was used to develop interactive SVG-ECG, not only providing a graphic ECG representation which is widely accepted by clinical physicians, but offering comparison and analysis of ECG data through interactivity of SVG.
