ICDs比心率调整器更先进更复杂，它可以利用小型计算机来感觉电流，对心脏进行监控以决定何时采取治疗性电击。

ICDs are considerably more advanced and complex than pacemakers and use small computers to sense electrical activity, monitor the heart and determine when and how to apply a therapeutic shock.

在电击治疗中，医生给患者使用肌肉松弛剂和麻醉剂，并让电流通过患者大脑的部分区域，电流可引发疾病短时间突然发作，有助于治疗抑郁症。

In ECT treatment, patients get a muscle relaxant and an anesthetic and an electrical current is passed to part of their brains, triggering a brief seizure that can help treat the depression.
