- Cardiovascular examination showed a normal first heart sound but a prominent pulmonic second sound, with no audible murmur of tricuspid insufficiency. 心血管檢查顯示,第一心音正常,但肺動脈第二心音亢進,未聽到三尖瓣關閉不全的雜音。
- The 3rd heart sounds is physiology sex, without pathology meaning. 第三心音是生理性的,沒有病理意義。
- S3 .The third heart sound (S3, or ventricular gallop) is low-pitched and best heard at the apex with the stethoscope bell. S3第三心音,又叫室性奔馬律,低音調,用鍾式聽診器在心尖處聽得最清楚。
- It also gives a safety design problem analysis using an electret capacitor microphone to pick-up the heart sound signals. 該電路涉及到放大、濾波、電平抬升等電路,並給出了安全設計問題,利用駐極體電容傳聲器來拾取心音信號。
- S4.The fourth heart sound (S4, atrial gallop, presystolic gallop) is also the result of altered ventricular compliance.Its cadence has been likened to the soft a of appendix. S4第四心音,又叫房性奔馬律,收縮期前奔馬律,也是心室順應性改變的結果。
- The heart sounds are muffled when the pericardial sac is distended with fluid. 當心包充滿液體時心音減弱。
- Huiying Liang.Iire artimo."A heart sound feature extraction algorithm based on wavelet decomposition and reconstructin,"IEEE,vol.20,no,3,PP.1539-1541,1998. 李勇;高小榕;郭愛雯.;基於連續小波變換得心音信號時頻分析
- "Cross the weald of the mind, through heart sound jump about, see small and softly, hear quietly, the bitterness love of[with] etc. is in the faraway distance. 穿越心靈的曠野,透過跳動的心音,細細地看,靜靜地聽,苦等的愛情在遙遠的距離之中。
- Firstly,the original heart sounds signal was preprocessed by Huang Transform. 首先利用黃變換對心音信號進行預處理;
- My heart beat thick in the course of the interview. 在面試過程中我的心跳得厲害。
- So, this paper uses mathematical morphology theory to catch heart sound envelope, and then composes the reference noise which is heavily correlative to the noise in the primary PCG signal. 在這裡本文又引入了數學形態學理論,利用它提取了心音信號的包絡,然後合成了自適應濾波需要的參考。 這樣得到的雜訊信號雖然在心音成份部分不能保證與原心音中的雜訊相關,但在心音間隙期二者是強相關的,利用這種相關性,在這裡濾去間隙期的雜訊信號,得到了分界更清晰的心音圖,為心音成份的識別打下基礎。
- An instrument consisting of microphones and recording equipment used to monitor and record heart sounds and murmurs. 心音描記圖由話筒和記錄裝置組成的儀器,用來監測和記錄心臟聲音和雜音
