本文观察了230例正常健康者无创性左室功能检查,各参数指标基本与当前国内外所报导的一致。其中对S.T.I各参数值直接测量和进行了回归方程计算,以校正心率影响,并将其结果与直接测量数据进行了比较讨论。本文强调了PEP/LVET比值较其他各参数之优点及使用价值。
This article observed 230 cases of normal healthy noninvasive left ventricular function tests, the basic parameters of the parameters reported at home and abroad are consistent. Among them, the parameters of S.T.I were measured directly and the regression equation was calculated to correct the influence of heart rate, and the results were compared with the direct measurement data. This article emphasizes the advantages and values of the PEP / LVET ratio over other parameters.
