This is particularly important when the conducting tissues between the sa node and the ventricles fail only from time to time . 尤其在窦房结和心房之间的传导组织有时发生故障时这点尤为重要。
The name tricuspid refers to the three flaps of tissue that guard the opening between the right atrium and the right ventricle . 三尖瓣这个名称与守卫着右心房和右心室开口的三块片状瓣膜有关。
An "atrially triggered" pacemaker can pick up the signals directly from the sa node and strengthen them before passing them to the ventricles . 一种“心房触发式心博器”就能从窦房结直接接收这种信号,并在传送到心房去之前还能将这种信号进行放大。
The ventricles make up the greater part of the heart 两个心室占心脏的大部分。
The ventricles rest almost twice as much as they work 5心室的休息时间几乎是工作时间的2倍。
