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。
