植入式心脏事件循环记录器

植入式循环记录仪是一种心脏监测设备,能够持续记录心律长达三年之久。它会通过胸部皮肤下植入的小型装置记录心脏的电信号并进行远程监测。

做手术的理由

可植入式循环记录仪可以帮助解答其他心脏监测设备无法解答的有关心脏的问题。它支持进行长期的心律监测。它可以捕捉标准心电图 (ECG or EKG) 或动态心电图监测仪由于一些心律异常很少发生而遗漏的信息。

例如,如果用标准心电图 (ECG) 检查来帮助查找昏厥的原因,它只能在几分钟监测期内(通常是 5 分钟左右)记录任何相关的心律异常。因为植入式循环记录器可以长时间监测心脏信号,所以它更有可能捕捉到下一次昏厥时的心脏活动。这些信息可以帮医生做出明确的诊断并制定治疗计划。

植入式循环记录器是一种较新的心脏监测设备。研究人员在过去的 10 年里评估了它们的安全性和优势。一项对 579 名昏厥患者的研究表明,与其他监测设备相比,植入式循环记录器对心律问题的诊断率更高。

研究人员还研究了植入式循环记录器在卒中患者中的价值。长期的心脏监测比 24 小时监测更能揭示导致卒中的心律问题。医生们用这些结果来指导血液稀释药物(抗凝治疗)的治疗,以防止再次卒中。

您所能期望的目标

您需要接受一个小手术来放置植入式环路记录器。该手术的风险包括感染或对装置的反应,这会导致切口部位发红。

术前

无需为该手术做特别准备。

术中

心脏监护器插入操作通常是在医生办公室完成的,需要局部麻醉。您的医生会造一个小切口,插入一个比钥匙或拇指驱动器更小的器械,然后封闭切口。该器械可以在体内留置最长 3 年。

结果

Your doctor will interpret the results of your test and call if he or she has any concerns. You'll likely need to see your doctor once or twice a year for routine checkups while the device is in place.

An implantable loop recorder is invisible and doesn't interfere with your daily activities. It has no patches or wires. You don't have to worry about getting the device wet while bathing or swimming.

An implantable loop recorder is considered safe for use during magnetic resonance imaging (MRI), but always let your doctor know about your implant before you schedule such an imaging test.

It's also possible that an implantable loop recorder might set off metal detectors, for example, at an airport. Your doctor can provide you with a device identification card to carry with you for such situations.
