Implantable loop recorders (ILRs) are effective in achieving symptom-rhythm correlation. Data on the diagnostic yield of ILRs, on nurse-led syncope clinics, and on nurse-led ILR implants are limited.
We evaluated the safety and efficacy of our nurse-led syncope clinic and nurse-led ILR implants.
A retrospective study of all consecutive patients undergoing nurse-led ILR implantations was performed between April 2016 and April 2018. Patients were referred from both nurse-led and physician-led clinics. Data were collected on baseline demographic characteristics, referral source, symptom-rhythm correlation, ILR findings, and subsequent changes to management. All ILRs were enrolled into remote monitoring with automatic arrhythmia detection, and all immediate (≤24 hours) ILR implant complications were recorded. Comparisons were made between nurse-led and physician-led clinics and subsequent outcomes.
A total of 432 patients with an ILR were identified: 164 (38%) from nurse-led and 268 (62%) from physician-led clinics; 200 (46%) were women (mean age 66.5 ± 18.2 years; mean follow-up duration 28.9 ± 9.5 months). Primary ILR indications were syncope (n = 251 [58%]), presyncope (n = 33 [7%]), palpitation (n = 39 [9%]), cryptogenic stroke (n = 78 [18%]), and other reasons (n = 31 [7%]). No immediate ILR implant complications occurred. Overall, 156 patients (36%) had a change in management as a direct result of ILR findings, with no overall differences between nurse-led and physician-led clinics (35% vs 36%; P = .7). More patients had newly diagnosed atrial fibrillation in physician-led clinics (15% vs 7%; P = .01), and more patients had pacemaker implants for bradycardia in nurse-led clinics (23% vs 13%; P < .01).
Nurse-led ILR implantation was safe and effective. Nurse-led syncope clinics achieved good symptom-rhythm correlation with resultant significant changes to management in comparison to physician-led clinics. Larger prospective studies are needed to evaluate their longer-term impact.
植入式环路记录器（ILR）在实现症状与节律相关性方面很有效。关于ILR的诊断率、护士主导的晕厥诊所及护士主导的ILR植入的数据有限。
我们评估了护士主导的晕厥诊所及护士主导的ILR植入的安全性和有效性。
对2016年4月至2018年4月期间所有接受护士主导的ILR植入的连续患者进行了一项回顾性研究。患者来自护士主导和医生主导的诊所。收集了关于基线人口统计学特征、转诊来源、症状与节律相关性、ILR检查结果及后续管理变化的数据。所有ILR均纳入具有自动心律失常检测功能的远程监测，并记录所有即刻（≤24小时）ILR植入并发症。对护士主导和医生主导的诊所及后续结果进行了比较。
共确定了432例植入ILR的患者：164例（38%）来自护士主导的诊所，268例（62%）来自医生主导的诊所；200例（46%）为女性（平均年龄66.5±18.2岁；平均随访时间28.9±9.5个月）。ILR的主要适应证为晕厥（n = 251 [58%]）、先兆晕厥（n = 33 [7%]）、心悸（n = 39 [9%]）、不明原因卒中（n = 78 [18%]）及其他原因（n = 31 [7%]）。未发生即刻ILR植入并发症。总体而言，156例患者（36%）因ILR检查结果导致管理发生改变，护士主导和医生主导的诊所之间无总体差异（35%对36%；P = 0.7）。在医生主导的诊所中，新诊断为房颤的患者更多（15%对7%；P = 0.01），在护士主导的诊所中，因心动过缓植入起搏器的患者更多（23%对13%；P < 0.01）。
护士主导的ILR植入是安全有效的。与医生主导的诊所相比，护士主导的晕厥诊所实现了良好的症状与节律相关性，从而使管理发生了显著变化。需要进行更大规模的前瞻性研究来评估其长期影响。
