Abstract：
To date, the ventricular myocardial band is the anatomical-functional model that best explains cardiac mechanics during systolic-diastolic phenomena in the cardiac cycle. The implications of the model fundamentally affect the anatomical interpretation of the ventricular myocardium, giving meaning to the direction that muscle fibers take, turning them into an object of study with potential clinical, imaging, and surgical applications. Re-interpreting the anatomy of the ventricular muscle justifies changes in the physiological interpretation, from its functional focus as a fiber unraveling the mechanical phenomena carried out during systole and diastole. We identify the functioning of the heart from the electrical and hemodynamic point of view, but it is necessary to delve into the mechanics that originate the hemodynamic changes observed flowmetrically, and that manifested during the pathology. In this review, the mechanical phenomena that the myocardium performs in each phase of the cardiac cycle are broken down in detail, emphasizing the physical displacements that each of the muscle segments presents, as well as a vision of their alteration and in which pathologies they are mainly identified. Visually, an anatomical correlation to the echocardiogram is provided, pointing out the direction of the segmental myocardial displacement by the strain velocity vector technique.
摘要：
迄今为止,心室心肌带是解释心动周期收缩-舒张现象时心脏力学的解剖学-功能模型.该模型的含义从根本上影响心室心肌的解剖学解释，赋予肌肉纤维的方向以意义，把它们变成具有潜在临床价值的研究对象，成像,和外科应用。重新解释心室肌的解剖结构证明了生理解释的变化，从其作为纤维的功能焦点中解开在收缩期和舒张期进行的机械现象。我们从电学和血液动力学的角度识别心脏的功能，但是有必要深入研究流动观察到的血液动力学变化的机制，在病理学中表现出来。在这次审查中,详细分解了心肌在心动周期的每个阶段中执行的机械现象，强调每个肌肉段呈现的物理位移，以及它们的改变和它们主要被识别的病理的愿景。视觉上,提供了与超声心动图的解剖学相关性，通过应变速度矢量技术指出节段性心肌位移的方向。
