- peak ejection time 最大射血时间
- 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. 获得了ASD、VSD的右心CFL,并发现在B组中ASD与VSD的CFL各具特点,ASD的CFL环体上下对称,环正峰值较VSD右移,VET随着RVSP升高而逐渐延长;
- 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:运用门控核素法及AQ法在较短时间内分别测定正常组和冠心病组的左室射血分数(LVEF)、左室最大射血率(LPER)、左室最大充盈率(LPFR)及左室最大充盈时间(LTPER),同时M超法测定LVEF作为心功能指标,并进行统计学分析。
- The parameters were EDV(end diastolic volume), ESV(end systolic volume), EF(ejection fraction), PER(peak ejection rate) and PFR(peak filling rate). 检测指标:EDV(舒张末期容积)、ESV(收缩末期容积)、EF(射血分数)、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). 结果与术前相比;LVEF显著减小(P<0.;01);E/A、IRT、ICT、Tei指数显著增大(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. 采用声学定量技术测量左室舒张末容积(EDV)、左室收缩末容积(ESV)、左室射血分数(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与左室峰值心房充盈率之比(PRFRPAFR)。 并以34例正常人为对照组。
- 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. 肺动脉射血加速时间(AT)及与射血时间(ET)的比值(AT/ET)轻度窒息组较正常组;重度窒息较轻度窒息及正常组缩短或降低(P<0.;01或<0
