g*******n 发帖数: 91 | 1 UW有一道题 是关于左室压力-容积环的, 说A-V shunt 导致前负荷增加 然后让选一个前负荷增加的PV LOOP 但解释的不很详细 请问 如何从PV loop判断前负荷, 除了横径 stroke volume 还要看什么 谢谢 | g*******n 发帖数: 91 | | g*******n 发帖数: 91 | | l*******6 发帖数: 34 | 4 Preload = ventricular EDV
AV shunt bypasses capillary beds and routes bld directly from arterial to
venous system. Increased preload causes a rightward widening of the PV loop,
which is a increased EDV. Please kindly correct me if I am wrong. Thanks |
