背景：虽然法洛四联症患者的“蹲”很有名，但这种现象的血流动力学机制尚未完全阐明。为了阐明蹲坐的机制，我们研究了蹲坐引起的主动脉搏动特性的变化。方法：12名健康的年轻人参加了这项研究。采用SphygmoCor （PWV Medical, Sydney, Australia）研究深蹲引起的中枢压力波形变化。结果：深蹲时的增强指数高于站立时(平均+/- SEM， 6.3 +/- 1.1 v 25.0 +/- 1.1
Background: Although "squatting" in patients with tetralogy of Fallot is famous, the hemodynamic mechanism of the phenomenon has not been fully elucidated. To clarify the mechanism of squatting, the change in aortic pulsatile property induced by squatting was investigated.Methods: Twelve healthy young adults were enrolled in this study. The change in central pressure waveform induced by squatting was investigated using SphygmoCor (PWV Medical, Sydney, Australia).Results: The augmentation index during squatting was higher than that during standing (mean +/- SEM, 6.3 +/- 1.1 v 25.0 +/- 1.1; P
