PPG：峰值压力梯度

在医学领域，尤其是在英国的专业文献和临床实践中，“Peak Pressure Gradient”（峰值压力梯度）是一个常用的血流动力学参数。为了简化书写和使用，该术语常被缩写为PPG。这一缩写在心血管生理学和诊断过程中尤为常见，用于评估血管或心脏瓣膜两端的压力差峰值，是判断血流梗阻程度的重要指标。

Peak Pressure Gradient具体释义

  • 英文缩写：PPG
  • 英语全称：Peak Pressure Gradient
  • 中文意思：峰值压力梯度
  • 中文拼音：fēng zhí yā lì tī dù
  • 相关领域： ppg 英国医学
