技術摘要:
一種具有表面電位轉換多導程數的即時心臟血管功能評估系統及其方法,其包含心電訊號量測單元、重建單元及評估參數單元,重建單元係利用心電訊號量測單元紀錄的心電訊號以重建於不同空間位置中未實際具有導程的心電訊號,並以計算評估參數演算法計算心電訊號的Q波及T波的時間差隨時間的不同在空間上表現的變異性,以評估其離散程度,進而判斷是否發生心臟血管疾病及定位心臟血管疾病的病灶位置。

A system and method for evaluating cardiovascular performance in real time and characterized by conversion of a surface potential into multi-channels are introduced. The system includes an electrocardiographic signal measuring unit, a reconstruction unit, and a parameter computation and assessment unit. The reconstruction unit reconstructs electrocardiographic signals (ECG signals) recorded by the electrocardiographic signal measuring unit, such that the ECG signals are reconstructed as ones located at different spatial positions but actually not having a channel. The method includes calculating a variation manifested spatially during an interval between a Q wave and a T wave of an ECG signal against time with a parameter computation and assessment algorithm, to evaluate its discreteness degree and thereby diagnose cardiovascular diseases (CVD) and locate lesions thereof.
