救命的心脏起搏器,就像一台生命的发动机,给衰竭的心脏注入新的动力。它曾因昂贵的价格而让普通百姓望尘莫及。如今,它越来越平民化。这个过程,就如选购手机所经历的一样。就让我们像了解手机一样,去了解一下功能、价格相差甚远的心脏起搏器。心脏正常的跳动,有赖于右心房最深处一个叫窦房结的结构。它准时规律地发出信号,并通过固定通路传到心房,促使心房收缩,将血液泵到心室,然后心室收缩,血液泵到身体各处。
A lifesaving heart pacemaker, like a living engine, injects new power into a failing heart. It was due to expensive prices so that ordinary people can not catch up. Today, it is becoming more and more common people. This process, just as the experience of the purchase of mobile phones. Let us know the same as the phone, to find out about the function, the price is far from a pacemaker. The normal heart beat, depends on the deepest part of the right atrium called the structure of the sinus node. It sends signals regularly and on time and through the fixed access to the atria, causing contraction of the atria, pumping blood to the ventricle, and then ventricular contraction, pumping blood throughout the body.
