| 2. | Bradycardia, if persistent, should be controlled by the insertion of a pacemaker as soon as possible .
如果持续出现心动过缓，应尽快使用起搏器。 |
| 3. | While this is commonly agreed upon, the vagal innervation of idioventricular pacemakers is not .
这点是人所公认的，而心室自身起撑点的迷走神经支配还未得到公认。 |
| 4. | The s-a node is often called the pacemaker of the heart because it establishes the basic rhythm at which the heart beats .
S-A结由于建立了心跳的基本节律，故常称为起搏点。 |
| 5. | As the early pacemakers were not implanted, the patient could reach them easily and control them .

| 6. | To implant a pacemaker anywhere in the body is to ask the tissues to carry an extra and unnatural weight .

| 7. | An increase in extracellular potassium does in fact shift the pacemaker within the sinus node from the cephalic to the caudal portion .

| 8. | At first, in the early 1950s, the patient wore his pacemaker outside his body, and wires passed through his skin to connect it to his heart .
最初，在五十年代初期，患者带一个体外心搏器、电线通过他的皮肤连接到心脏。 |
| 9. | 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。 |
