It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P＜0.01～0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P＜0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性，负荷后即刻，老年组射血前期延长(P＜0.05)，射血前期与射血期比值加大(P＜0.05)，青年组无变化，提示年龄因素亦影响STI，但由于静息状态下得到代偿，STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化，而负荷后即刻老年组PEF延长，PEP/LVET加大，提示STI是检测左室收缩功能的敏感指标。4、随年龄增长，心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r＝0.958、0.956、0.986及0.966，P均＜0.001)，舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r＝-0.958、-0.875及-0.937，P＜0.01～0.001)。

Regional tardokinesis was identifiedin 48 of 150 segments: 27 segments had a normal magnitude ofwall motion, 18 were hypokinetic, and 3 were severely hypokinetic/akinetic.

轻度运动减退表明延迟收缩运动，而剩下的严重运动减退/运动不能则发生在收缩早期，反应了邻近心肌收缩的被动效应。

There was no statistically significant difference in parameters of IVS motion between obstructive and nonobstructive HCM.The data of hypertrophic LVPW motion were lower than those of normal subjects,as well as those of nonhypertrophic LVPW in HCM group.

左室后壁肥厚者收缩期及舒张早期的DTI测值多低于正常，而左室后壁不肥厚者收缩期指标无明显变化，舒张早期指标低于正常；两者相比，前者收缩期及舒张早期各参数多低于后者。

Results Compared with normal myocardium, the peaks of strain rate curve at systole, early diastole and late diastole of ischemic myocardium all reduced, the postsystolic shortening wave appeared before operation.

结果术前缺血心肌应变率曲线中收缩期、舒张早期和舒张晚期SR峰值均小于正常节段并可出现收缩后收缩波。

This article is about adoption of Watson's caring theory for a 38-year-old primigravida, who presented with early uterine contraction and was hospitalized for tocolysis. Clinical data was collected and assessed by interview, observation and body assessment during October 17th and November 15th, 2006. We found the client worried about the fetal health owing to premature labor and felt frustrated about limitations and demands of learning and accomadating herself to high-risk labor, resulting in anxiety, constipation and health-seeking behaviors.
