BACKGROUND
Pneumatic artificial hearts have played an important role in supporting the circulation in patients before cardiac transplantation. Pneumatic hearts have also been used for permanent cardiac replacement, but most agree they have serious limitations.
METHODS
Several groups are now developing electric artificial hearts in which electrical energy crosses the skin using a wireless technique. The electrical energy powers a small direct-current motor, which actuates the blood pump.
RESULTS
Important progress in these devices has resulted in animal survival with electric hearts of more than 1 year.
CONCLUSIONS
Extensive bench testing and animal testing will be performed before the initial clinical use of these devices will be initiated. One of the early scientific achievements of the 21st century will be the initial use of the electric artificial heart in humans.
背景
气动人工心脏在心脏移植前支持患者循环方面发挥了重要作用。气动心脏也已用于永久性心脏替代，但大多数人认为它们有严重局限性。
方法
目前有几个团队正在研发电动人工心脏，其电能通过无线技术穿过皮肤。电能为一个小型直流电机供电，该电机驱动血泵。
结果
这些设备取得了重要进展，使得动物使用电动心脏存活超过1年。
结论
在这些设备首次临床应用之前，将进行广泛的台架测试和动物测试。21世纪早期的一项科学成就将是电动人工心脏首次应用于人类。
