中文摘要 | 背景:主動脈閉銷不全一向被認為是一純舒張期事件。但是由血流動力學的觀 點,在等容積收縮期左心室壓力仍將低於主動脈壓力。因此本實驗的目的在評 估「主動脈閉銷不全的逆流波持續至等容積收縮期結束」的可能性。 方法與結果:二十位主動脈閉鎖不全的病人被安排接受心音圖、心電圖、及心 臟超音波的同時記錄。無論脈衝式或連續性杜卜勒超音波檢查均顯示主動脈閉 銷不全的逆流波分別持續至第一心音開始後71±16或68±20微秒。 結論;本研究證實主動脈閉銷不全通常持續至等容積收縮期結束,而不是一純 舒張期事件。 |
英文摘要 | Background. Aortic regurgitation has generally been considered to be a purely diastolic event. The purpose of this study was to evaluate the possibility that, on the hemodynamic basis, the regurgitant flow may persist till the end of the isovolumic contraction phase. Methods and Results. Twenty patients (aged 69 ± 12 years, 9 males and 11 females) with aortic regurgitation were included. Simultaneous recordings of phonocardiography, electrocardiography, and echocardiography were done for each. The aortic regurgitant signal persisted till 71 ± 16 and 68 ± 20 ms after the onset of the first heart sound in the pulsed and continuous Doppler tracings, respectively. Conclusions. The aortic regurgitant flow signal is not a purely diastolic event and usually extends till the end of the isovolumic contraction phase. |
