摘要
目的探讨埋藏式心脏事件记录器(implantable loop recorder,ILR)在不明原因晕厥患者中的诊断价值。方法对8例原因不明的晕厥患者植入ILR,定期随访研究,并进行回顾性分析。结果植入ILR后随访12-36个月,平均(22±4)个月。其中4例患者在随访期内未有晕厥或晕厥先兆发生,4例在随访期内出现晕厥,其中1例系快速心房颤动转复为窦性心律、伴R-R长间歇,1例患者在随访期间出现近似晕厥,程控发现心室率明显增快,复查心脏超声,发现肥厚性心肌病,予以美托洛尔口服治疗后随访未再出现晕厥或晕厥先兆。2例晕厥发作时经程控发现为非心源性。结论ILR对临床鉴别有困难且发作次数较多、又不能排除心律失常性晕厥具有一定的鉴别诊断价值。
Objective To investigate the diagnostic value of implantable loop recorder(ILR)in patients with unexplained syncope.Methods ILR was implanted into 8 patients with syncope of unknown origin,followed up regularly and analyzed retrospectively.Results After ILR implantation,the follow-up period ranged from 12 to 36 months,with an average of(18±4)months.Five patients had no similar syncope or syncope in the follow-up period,two patients had syncope in the follow-up period,non-cardiogenic syncope was found by programmed control,one patient had similar syncope during the follow-up period,and the ventricular rate was slightly faster by programmed control.Therefore,echocardiography was reexamined and hypertrophic cardiomyopathy was found.No syncope or premonitory syncope was found after oral metoprolol treatment.Conclusion ILR has diagnostic value for patients with suspected arrhythmia who have dif ficulty in clinical identi fication and have more attacks,and it has certain differential diagnostic value for recurrent arrhythmic syncope which can not be ruled out.
