在所有的人体器官中，心脏在某种意义上是最简单的。它所要做的就是在它的主人的一生中通过收缩和扩张大约25亿次来泵血。心脏也是人体内研究最多的器官之一，可能是因为心脏衰竭，无论是机械性的还是电性的，在西方世界仍然是头号死因。心脏是一个四腔泵，由两个串联的泵组成。如第11章所述，一个泵（右心）驱动血液通过肺部（肺循环），然后回到心脏，而另一个泵（左心）驱动含氧血液在身体周围（体循环）。心脏机械活动的协调是由电信号提供的，这是本章研究的主题。
Of all of the human organs, the heart is in some sense the simplest. All it has to do is pump blood by contracting and expanding about 2.5 billion times during the lifetime of its owner. The heart is also one of the most studied organs of the body, probably because heart failure, either mechanical or electrical, remains the number one cause of death in the Western world.The heart is a four-chambered pump, consisting of two pumps arranged in series. As is described in Chapter 11, one pump (the right heart) drives blood through the lungs (the pulmonary circulation) and then back to the heart, while the other pump (the left heart) drives the oxygenated blood around the body (the systemic circulation). Coordination of the mechanical activity of the heart is provided by an electrical signal, which is the topic of study in this chapter.
