本文应用舒张充盈初期（ＣＲ间期）这一无创性指标，结合ＯＦ间期和总舒张时间（ＴＲＴ）分析，对６６例正常人和６４例高血压病人进行现察，发现正常高龄（＞４５岁）组的ＣＲ间期明显大于正常低龄（＜４５岁）组。高血压高龄（＞４５岁）组的ＣＲ间期显著低于正常高龄组。提示随着年龄增，左室舒张功能存在减退倾向。高血压高龄组除存在左室主动舒张功能减退这一因素外，尚有左房压的明显增高，认为ＣＲ间期结合ＯＦ间期和ＴＲＴ综合分析，是一个判断左室舒张功能和左房压的校好指标。
In this paper, noninvasive indicators of early diastolic filling (CR interval), combined with OF interval and total diastolic time (TRT) analysis of 66 normal subjects and 64 cases of hypertensive patients were observed and found that normal age (> 45 CR) was significantly longer than that of normal (<45 years old) group. The CR interval in hypertension group (> 45 years old) was significantly lower than that in normal group. Prompted with age, left ventricular diastolic dysfunction tend to decline. In addition to the presence of left ventricular active diastolic dysfunction in elderly patients with hypertension, there is a significant increase in left atrial pressure, CR interval combined with OF interval and TRT comprehensive analysis is a judgment of left ventricular diastolic function and left atrial pressure The school’s good indicators.
