技術說明

本發明為一種將代表心臟機械生理反應之心震圖訊號進行定序，並判斷心臟搏動週期內心瓣膜開閉、心肌收縮及血流脈衝等心臟搏動事件發生時序之方法。其係利用一感測單元偵測一心臟之一心臟機械生理狀態，進而產生一心臟心震圖訊號，接續透過複數特徵點與一心搏週期進行解析，而獲得心臟搏動事件定序資料，心臟搏動事件定序資料為包含複數個定序圓圖形，藉此簡化心臟機械生理狀態是否異常的判斷方式，既使在較少樣本的情況下，亦可輕易了解心臟生理狀態是否異常。 This invention is regarding the sequencing methods of Seismocardiogram (SCG) signals which representing the cardiac mechanical behavior. By using the sequencing information, the critical cardiac timing events such as open / close of hear6t values, myo-cardiac contraction, blood impulsion can be detected. With single channel sensor, a cardiac mechanical response (SCG) will be monitored. The multiple feature points of SCG in one single cardiac cycle can then be analyzed to generate the cardiac timing events sequencing information. This sequencing information may be plotted as a series concentric sequencing circles and used to identifying the abnormalities of the onset of critical cardiac timing events for cardiovascular diseases patients.
