- peak ejection time 最大射血時(shí)間
- CFL was plotted in each case. Some difference was observed between ASD and VSD. The features of ASD were (1) symmetrical CFL, (2) positive peak of CFL shifting to right and (3) positive relationship between RVSP and ventricular ejection time. 獲得了ASD、VSD的右心CFL,并發(fā)現在B組中ASD與VSD的CFL各具特點(diǎn),ASD的CFL環(huán)體上下對稱(chēng),環(huán)正峰值較VSD右移,VET隨著(zhù)RVSP升高而逐漸延長(cháng);
- METHODS:Left ventricular ejection fraction(LVEF),left peak ejection rate(LPER),left peak filling rate(LPFR)and left peak filling time(TPFR)were measured by gated nuclide method and AQ method. At the same time, LVEF was measured by M-us method. 方法：運用門(mén)控核素法及AQ法在較短時(shí)間內分別測定正常組和冠心病組的左室射血分數（LVEF）、左室最大射血率（LPER）、左室最大充盈率（LPFR）及左室最大充盈時(shí)間（LTPER），同時(shí)M超法測定LVEF作為心功能指標，并進(jìn)行統計學(xué)分析。
- The parameters were EDV(end diastolic volume), ESV(end systolic volume), EF(ejection fraction), PER(peak ejection rate) and PFR(peak filling rate). 檢測指標:EDV(舒張末期容積)、ESV(收縮末期容積)、EF(射血分數)、PER(峰值排空率)、PFR(峰值充盈率)。
- LV ejection fraction(LVEF) was significantly decreased (P<0.01) and left ventricular ejection time (ET) was also significantly shortened(P<0.05). 結果與術(shù)前相比;LVEF顯著(zhù)減小(P<0.;01);E/A、IRT、ICT、Tei指數顯著(zhù)增大(P<0
- Left ventricle end diastolic volume(EDV), end systolic volume(ESV), ejection fraction(EF), peak ejection rate(PER), peak rapid filling rate(PRFR) and peak atrium filling rate(PAFR) were also measured, PRFR PAFR were calculated. 采用聲學(xué)定量技術(shù)測量左室舒張末容積(EDV)、左室收縮末容積(ESV)、左室射血分數(EF)、左室峰值排空率(PER)、左室峰值快速充盈率(PRFR)、左室峰值心房充盈率(PAFR)、左室峰值快速充盈率與左室峰值心房充盈率之比(PRFRPAFR)。 并以34例正常人為對照組。
- Severe asphyxia group had a shorter acceleration time and more minished ratio(AT/ET) of acceleration time(AT) to ejection time(ET) than either of normal and mild asphyxia group,so did mild asphyxia group than those of normal group. 肺動(dòng)脈射血加速時(shí)間(AT)及與射血時(shí)間(ET)的比值(AT/ET)輕度窒息組較正常組;重度窒息較輕度窒息及正常組縮短或降低(P<0.;01或<0
- left ventricular ejection time index 左心室射血時(shí)間指數
- left ventricular ejection time, LVET 左心室射血時(shí)間
- Fruit juices ferment if they are kept a long time. 果汁若是放置很久，就會(huì )發(fā)酵。
- Time is sometimes called the fourth dimension. 時(shí)間有時(shí)被稱(chēng)為第四度空間。
- I think the work can be completed ahead of time. 我認為這項工作能提前完成。
- He will come on time even though it rains. 即使下雨，他還是會(huì )準時(shí)來(lái)的。
- Reading occupies most of my free time. 閱讀占去了我大部分的閑暇時(shí)間。
- ratio of preejection period to left ventricular ejection time 射血前期與左室射血時(shí)間比率
- Many mountaineers have reached that mountain peak. 許多登山家都登上過(guò)那座大山的頂峰。
- We have a precipitous climb to the peak. 我們向著(zhù)陡峭山頂攀登。
- I need some time to orient my thinking. 我需要一些時(shí)間來(lái)使我的思想適應。
