Abstract

BACKGROUND

Trans-mitral Doppler produces complex patterns with a great deal of variability. There are several confusing numerical measures and indices to study these patterns. However trans-mitral Doppler produces readymade data visualization by pattern generation which could be interpreted by pattern analysis. By following a systematic approach we could create an order and use this tool to study cardiac function.

PRESENTATION OF THE HYPOTHESIS

In this new approach we eliminate the variables and apply pattern recognition as the main criterion of study. Proper terminologies are also devised to avoid confusion. In this way we can get some meaningful information.

TESTING THE HYPOTHESIS

Trans-mitral Doppler should be seen as patterns rather than the amplitude. The hypothesis can be proven by logical deduction, extrapolation and elimination of variables. Trans-mitral flow is also analyzed vis-à-vis the Starling's Law applied to the left atrium.

IMPLICATIONS OF THE HYPOTHESIS

Trans-mitral Doppler patterns are not just useful for evaluating diastolic function. They are also useful to evaluate systolic function. By following this schema we could get useful diagnostic information and therapeutic options using simple pattern recognition with minimal measurements. This simplified but practical approach will be useful in day to day clinical practice and help in understanding cardiac function better. This will also standardize research and improve communication.

摘要

背景

经二尖瓣多普勒检查会产生具有很大变异性的复杂模式。有几种令人困惑的数值测量方法和指标来研究这些模式。然而，经二尖瓣多普勒检查通过模式生成产生现成的数据可视化，可通过模式分析进行解释。通过遵循系统的方法，我们可以创建一种秩序，并使用这个工具来研究心脏功能。

假设的提出

在这种新方法中，我们消除变量，并将模式识别作为主要研究标准。还设计了恰当的术语以避免混淆。通过这种方式，我们可以获得一些有意义的信息。

假设的验证

经二尖瓣多普勒检查应被视为模式而非幅度。该假设可通过逻辑推理、外推法和变量消除来证明。还相对于应用于左心房的斯塔林定律对经二尖瓣血流进行分析。

假设的意义

经二尖瓣多普勒模式不仅有助于评估舒张功能，也有助于评估收缩功能。通过遵循这种模式，我们可以使用简单的模式识别和最少的测量获得有用的诊断信息和治疗方案。这种简化但实用的方法将在日常临床实践中有用，并有助于更好地理解心脏功能。这也将使研究标准化并改善交流。
