To evaluate the efficacy of the implantable loop recorder (ILR) in establishing symptom-rhythm correlation in patients with unexplained syncope.
Implantable loop recorders (ILR, Reveal Plus(9526), Medtronic Inc.) were implanted in 10 patients [aged 14 - 78 (41 +/- 22) years, 6 female] with unexplained syncope from October 2002 to May 2005. Syncopal episodes were (4.5 +/- 1.4) patients.
During the monitoring period [8 - 21 (15.3 +/- 3.6) months], there were 24 times syncopal episodes in 6 patients. A total of 211 arrhythmia events were documented by ILR in 7 patients and symptom-rhythm correlation could be established in these 7 patients. In 2 patients, there were no recurrent syncopes and no arrhythmia events could be recorded. In 1 patient, syncope was caused by reasons other than arrhythmia.
ILR is useful in determining the presence or absence of an arrhythmia during symptoms of syncope when conventional diagnostic testing, such as electrocardiogram, Holter monitoring, and/or external loop recording, is inconclusive.
评估植入式循环记录仪（ILR）在不明原因晕厥患者中建立症状与节律相关性的疗效。
2002年10月至2005年5月，对10例不明原因晕厥患者[年龄14 - 78（41±22）岁，6例女性]植入植入式循环记录仪（ILR，Reveal Plus(9526)，美敦力公司）。晕厥发作患者为（4.5±1.4）例。
在监测期[8 - 21（15.3±3.6）个月]内，6例患者发生24次晕厥发作。ILR记录到7例患者共211次心律失常事件，且在这7例患者中可建立症状与节律相关性。2例患者无复发性晕厥，未记录到心律失常事件。1例患者晕厥由心律失常以外的原因引起。
当传统诊断测试，如心电图、动态心电图监测和/或外部循环记录无法得出结论时，ILR有助于确定晕厥症状期间是否存在心律失常。
