患有奥斯·弗林特的患者的多普勒和回声心脏学特征
1Department of Medicine, University of Wisconsin Medical School, Madison.
奥斯·弗林特声是由一个大动脉缺陷喷气击中前额叶叶片引起的,使其振动. 这项研究使用多普勒和心声回声学来识别喷流.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 声学分析 声学分析
背景情况:
- 奥斯·弗林特是已知的临床发现,在患有大动脉衰竭的患者.
- 它的确切起源一直受到争议,随着时间的推移提出了各种理论.
研究的目的:
- 为了调查奥斯·弗林特声的起源.
- 利用多普勒和心声成像来阐明它的病理生理学.
主要方法:
- 评估了51名患有显著的大动脉缺陷和正常心心膜的患者.
- 将患者分为两组:可听到的奥斯·弗林特声 (AFM+) 和没有声 (AFM-).
- 进行全面的心声回声和多普勒检查,以评估心脏结构,功能和流动动力学.
主要成果:
- 在大动脉缺陷喷流的方向上发现了显著的差异,在AFM+组中,更高的频率指向了中枢.
- 在AFM+组中,局部前额叶叶片扭曲和覆盖大动脉缺陷喷气的多普勒条纹在AFM+组中更频繁.
- 两组之间没有观察到传导流速,友膜梯度或友膜预闭的显著差异.
结论:
- 奥斯·弗林特声的主要原因是指向前额叶叶状叶片的大动脉缺陷喷射.
- 这种相互作用会导致传单的扭曲和振动,产生声的特征声音.
- 这项研究驳斥了涉及功能性额头管狭窄或腹性额头管吐的理论.

Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...
Assessment of the Cardiovascular System IV: Auscultation
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
