Computerized cardiovascular waveform processing has become a necessary and fundamental tool in the analysis of physiologic data. The availability of numerous commercial data-analysis programs has significantly enhanced the efficiency of waveform analysis. Many such programs come with their own programming language, which enables the researcher to create an application program suited to a specific series of calculations. Once written, an application program can significantly increase the efficiency with which data from a specific experiment can be analyzed. However, creating or modifying a program for each new experimental protocol can be time-consuming, especially in the error-detection and verification stages. Single-purpose programs also prove somewhat inflexible to unexpected changes in experimental formats. These problems suggested the need for a more flexible program, but one that is nevertheless specifically suited to the analysis of cardiovascular signals. This need led to the development of a program designed in collaboration with surgeons and physiologists. This program addresses some important analysis problems in cardiovascular research, and allows the user to survey and manipulate cardiovascular waveforms in an intuitive and spontaneous manner.
计算机化心血管波形处理已成为生理数据分析中必要的基础工具。众多商业数据分析程序的出现显著提高了波形分析的效率。许多此类程序都有自己的编程语言，这使研究人员能够创建适合特定系列计算的应用程序。一旦编写完成，应用程序可以显著提高分析特定实验数据的效率。然而，为每个新的实验方案创建或修改程序可能很耗时，尤其是在错误检测和验证阶段。专用程序在面对实验格式的意外变化时也显得有些僵化。这些问题表明需要一个更灵活的程序，但这个程序仍要特别适合心血管信号的分析。这种需求促使开发了一个与外科医生和生理学家合作设计的程序。该程序解决了心血管研究中的一些重要分析问题，并允许用户以直观、自然的方式查看和处理心血管波形。
