Abstract

• L-wave is caused by abrupt elevation and gradual decrease of LV diastolic pressure. • Color M-mode echocardiography demonstrates “L” wave of LA slow propagation. • Pulmonary venous reservoir function and LA conduit function caused diastolic LA flow.

摘要

• L波由左心室舒张压的突然升高和逐渐降低引起。

• 彩色M型超声心动图显示左心房缓慢传播的“L”波。

• 肺静脉储血功能和左心房管道功能引起舒张期左心房血流。
