Since the original descriptions of the radiologic appearance of implantable cardiac defibrillators by Lurie et al. [1] and Goodman et al. [2] in 1985, rapid growth has occurred in the complexity and variety of models available. Originally, all devices were surgically placed in or on the pericardium. Now, some devices are inserted by intravascular catheters with part of the device buried in the chest wall, avoiding the need for thoracotomy. Initially, these devices were used as defibrillators for treatment of tachyarrythmia and ventricular fibrillation. Now they serve as pacemakers for both tachy- and bradyarrhythmias and can act as cardioverters or defibrillators if required. Radiologists must be familiar with the appearances of these devices as their use becomes more widespread. In this article, the electrophysiology of these devices is briefly reviewed and the typical radiologic appearances are presented along with common radiologically recognizable complications.
自1985年Lurie等人[1]和Goodman等人[2]首次描述植入式心脏除颤器的放射学表现以来，可用模型的复杂性和多样性迅速增加。最初，所有设备都通过手术放置在心包内或心包上。现在，一些设备通过血管内导管插入，部分设备埋入胸壁，避免了开胸手术的需要。最初，这些设备用作治疗快速心律失常和心室颤动的除颤器。现在它们既用作快速和缓慢性心律失常的起搏器，并且在需要时还可以用作心脏复律器或除颤器。随着这些设备的使用越来越广泛，放射科医生必须熟悉它们的表现。在本文中，简要回顾了这些设备的电生理学，并展示了典型的放射学表现以及常见的放射学可识别并发症。
