Conventional pacing systems consist of a pacemaker and one or more leads threaded from the device pocket through veins into the heart conducting the pacing therapy to the desired pacing site. Although these devices are effective, approximately one in eight patients treated with these traditional pacing systems experiences a complication attributed to the pacemaker pocket or leads. With the technological advances in electronics, leadless pacemakers that small enough to implant within the heart were introduced. Leadless pacemakers have been developed to overcome many of the challenges of transvenous pacing including complications related to leads or pacemaker pockets. This review aims to provide an overview of advantages of leadless pacemaker, complications and limitations of leadless pacemaker, leadless pacemaker candidate, and future directions of this promising technology.
传统的起搏系统由起搏器和一根或多根导线组成，这些导线从设备口袋穿过静脉进入心脏，将起搏治疗引导到所需的起搏部位。尽管这些设备很有效，但大约每 8 名接受传统起搏系统治疗的患者中就有 1 名会出现与起搏器口袋或导线相关的并发症。随着电子技术的进步，人们引入了体积足够小可以植入心脏内部的无导线起搏器。无导线起搏器的开发是为了克服许多经静脉起搏的挑战，包括与导线或起搏器口袋相关的并发症。本文旨在概述无导线起搏器的优势、无导线起搏器的并发症和局限性、无导线起搏器的候选者以及这项有前途的技术的未来方向。
