起搏器是医生在心率不正常的人身上安置的一个小装置。如果心脏跳动过慢,起搏器就会通过电子信号帮助心脏重拾正常频率。另外一些设备包含除颤器,它会在心脏跳动过快时进行电击。起搏器既有永久使用型,也有短时安装型,但是有一点可以确定:发展中国家有越来越多人患上心脏病,起搏器的需求量越来越大。然而,费用问题相当棘手。购买和植入一个起搏器需要5000至15000美元。
Pacemakers are small devices that doctors place on people with abnormal heartbeats. If the heart beats too slowly, the pacemaker helps the heart regain its normal frequency with electrical signals. Other devices include a defibrillator, which shocks when the heart beats too fast. Pacemakers both permanent use, but also short-term installation, but one thing is certain: more and more people in developing countries suffer from heart disease, pacemakers demand more and more. However, the cost issue is tricky. It costs $ 5,000 to $ 15,000 to buy and implant a pacemaker.
