    摘要: 心臟疾病在國人主要死因排行榜上始終居高不下，因
    此診斷心臟疾病的心血管疾病專家防治系統，扮演了
    極重要的角色。本系統利用電腦上的藍芽接收器接收
    可攜式心電圖儀器端發送出來的訊號，經過QRS 偵測，
    挑出人生命重要的指標R 波，計算其R-R interval 後，
    運算出心率變異(HRV)之各項指標，做為評估致死型心
    臟病（SCD）危險因子。同時本本致死型心臟病之偵
    測，其中利用的技術為template matching 和跨越零值
    方法，當SCD 事件發生時，系統會在八秒鐘內發出
    SCD 警報，以搶救生命。在測試方面，SCD 的樣本取
    自於 PhysioNet Sudden Cardiac Death Holter database
    的20 個SCD 病患，結果顯示我們的演算法有95%以
    上成功偵測到SCD 發生;然而，以後努力的目標為將
    SCD 偵測器、ECG 生物辨識系統和醫院資料庫結合
    起來，形成一個強有力的系統，可用以評估心血管之
    健康。
    The death caused by heart diseases has become a serious
    problem in the modern society, how to efficiently
    diagnose heart diseases plays an important role recently.
    This system uses the Bluetooth port on the computer to
    receive the signals from the portable instrument, and
    passes the bio-signal data directly to hospital database,
    which is also embedded the ECG biometric system for
    personal security. The desktop system detects R waves
    and computes heart rate variability (HRV) after
    calculating R-R intervals in order to predict sudden
    cardiac death (SCD). In addition to SCD prediction, this
    research focused on (SCD) detection. The techniques for
    SCD detections involved the template matching with
    improved crossing zero method. When SCD happens, the
    system will send out the SCD alarm within eight seconds
    in order to rescue person’s life. For the testing process,
    twenty SCD patients of PhysioNet Sudden Cardiac Death
    Holter database are evaluated. The results showed our
    algorithms that have 95% accuracy to detect SCD
    successfully. In the future, the system may become a
    powerful system to evaluate personal cardiovascular
    health.
