利用植入式心电记录器(Implantable loop recorder,ILR)可在长达数年的时间内连续记录心电信号。对于反复发作而原因不明的晕厥患者,安装ILR相对于常规检查手段可获得更高的确诊率。本文介绍了ILR原理及其临床应用的优越性,对ILR在晕厥诊断、心肌梗死后心律失常记录方面的应用进展做了综合评述。 Implantable loop recorders (ILRs) continuously record ECG signals over a period of up to several years. For recurrent and unexplained syncope in patients with ILR installation relative to conventional examination methods to obtain a higher diagnosis rate. This article describes the principle of ILR and its clinical application of the superiority of ILR in syncope diagnosis, myocardial infarction arrhythmia records made a comprehensive review of the progress made.
