PS：收缩期峰值

“Peak Systolic”（英文缩写为PS）是医学领域中，尤其是英国医学文献中常用的专业术语，用于便捷书写与交流。该术语的中文对应含义为“收缩期峰值”，主要描述心脏收缩周期内血压或血流速度达到的最高数值，是心血管功能评估的重要指标之一，广泛应用于临床诊断与医学研究中。

Peak systolic and diastolic strain rates also increased significantly after bosentan treatment, the results indicate, although systolic and diastolic blood pressures were not affected.
结果表明，应用波生坦后，尽管收缩期和舒张期血压没有变化，收缩末期和舒张期心室体积比例明显升高。
Methods Peak systolic blood flow changes of carotid artery and basilar artery in the patterns and frequency were observed by Transcranial Doppler in94 cases of hypertension.
方法利用经颅多普勒检测94例高血压病的颈内动脉和基底动脉收缩峰血流的改变及频普的形态。
Objective To probe the value of mitral annulus peak systolic flow velocity and systolic displacement in evaluating left ventricular systolic function of dilated cardiomyopathy patients.
目的探讨二尖瓣环收缩期峰值(PS)速度及收缩期位移评价扩张型心肌病患者左室收缩功能的价值。
Finally, pulsed Doppler was used to collect spectra and measure the peak systolic velocity ( PSV ), end-diastolic velocity, resistance index and pulsate index.
最后用脉冲式多普勒采集频谱，测量收缩期峰值(PS)血流速度、舒张末期血流速度、阻力指数和搏动指数等。
