无导线心脏植入装置的研究进展

Research progress of leadless cardiac implantable devices

心脏植入装置在临床已得到广泛应用,但传统的经静脉心脏植入装置因导线、囊袋的存在易出现感染等一系列并发症。对感染高危人群而言,无导线心脏植入装置因没有导线和囊袋而独具优势。本文基于目前已有的临床证据及临床应用,主要介绍无导线心脏植入装置的心室起搏功能、房室同步功能、除颤功能及心室同步化治疗的尝试,同时对该装置的优劣势以及目前临床使用的推荐等方面进行综述。

Cardiac implantable devices are widely used in clinical practice.However,traditional transvenous pacemakers are associated with a series of complications such as infection due to the presence of leads and pockets.Leadless cardiac implantable devices,without leads or pockets,obtain unique advantages among the populations at high risk of infection.This article mainly provides an overview of the ventricular pacing function,atrioventricular synchronization function and defibrillation function of leadless pacemakers,and attempts at ventricular resynchronization therapy based on the existing clinical evidences and clinical applications at present.It also reviews the advantages and disadvantages of the devices,and current clinical recommendations.
