- 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)。
- 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。
- 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。
